Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Unreleased

Added

  • Adds PartiQLValueTextWriter implementation of date, time, and timestamp values

Changed

  • Behavioral change: The planner now does NOT support the NullType and MissingType variants of StaticType. The logic is that the null and missing values are part of all data types. Therefore, one must assume that the types returned by the planner allow for NULL and MISSING values. Similarly, the testFixtures Ion-encoded test resources representing the catalog do not use "null" or "missing".
  • Behavioral change: The INTEGER/INT type is now an alias to the INT4 type. Previously the INTEGER type was unconstrained which is not SQL-conformant and is causing issues in integrating with other systems. This release makes INTEGER an alias for INT4 which is the internal type name. In a later release, we will make INTEGER the default 32-bit integer with INT/INT4/INTEGER4 being aliases per other systems. This change only applies to org.partiql.parser.PartiQLParser, not the org.partiql.lang.syntax.PartiQLParser.
  • The deprecated SqlLayout and SqlDialect (which had stack overflow issues) has been replaced by the optimized version. The API is slightly different (append vs prepend) and generic method names have been replaced with more descriptive names (transform and print).

Deprecated

  • We have deprecated org.partiql.type.NullType and org.partiql.type.MissingType. Please see the corresponding information in the "Changed" section. In relation to the deprecation of the above, the following APIs have also been deprecated:
    • org.partiql.type.StaticType.MISSING
    • org.partiql.type.StaticType.NULL
    • org.partiql.type.StaticType.NULL_OR_MISSING
    • org.partiql.type.StaticType.asNullable()
    • org.partiql.type.StaticType.isNullable()
    • org.partiql.type.StaticType.isMissable()
    • org.partiql.type.StaticType.asOptional()
    • org.partiql.type.AnyOfType()
    • org.partiql.value.PartiQLValueType.NULL
    • org.partiql.value.PartiQLValueType.MISSING

[0.14.5]

Added

  • partiql-ast: adds warning not to implement AstVisitor interface directly. Please extend AstBaseVisitor instead.
  • partiql-plan: adds warning not to implement PlanVisitor interface directly. Please extend PlanBaseVisitor instead.

Changed

  • Change StaticType.AnyOfType's .toString to not perform .flatten()
  • Change modeling of COALESCE and NULLIF to dedicated nodes in logical plan
  • Function resolution logic: Now the function resolver would match all possible candidate (based on if the argument can be coerced to the Signature parameter type). If there are multiple match it will first attempt to pick the one requires the least cast, then pick the function with the highest precedence.
  • Behavioral change: The COUNT aggregate function now returns INT64.

Deprecated

  • The current SqlBlock, SqlDialect, and SqlLayout are marked as deprecated and will be slightly changed in the next release.
  • Deprecates constructor and properties variableName and caseSensitive of org.partiql.planner.PlanningProblemDetails.UndefinedVariable in favor of newly added constructor and properties name and inScopeVariables.

Fixed

  • StaticType.flatten() on an AnyOfType with AnyType will return AnyType
  • Updates the default .sql() method to use a more efficient (internal) printer implementation.
  • Fixes aggregations of attribute references to values of union types. This fix also allows for proper error handling by passing the UnknownAggregateFunction problem to the ProblemCallback. Please note that, with this change, the planner will no longer immediately throw an IllegalStateException for this exact scenario.

  • Added async version of physical plan evaluator PartiQLCompilerAsync.
    • The following related async APIs have been added:
      • org.partiql.lang.compiler -- PartiQLCompilerAsync, PartiQLCompilerAsyncBuilder, PartiQLCompilerAsyncDefault, PartiQLCompilerPipelineAsync
      • org.partiql.lang.eval -- PartiQLStatementAsync
      • org.partiql.lang.eval.physical -- VariableBindingAsync

      • JMH benchmarks added to partiql-lang: PartiQLCompilerPipelineBenchmark and PartiQLCompilerPipelineAsyncBenchmark

Changed

  • Function resolution logic: Now the function resolver would match all possible candidate(based on if the argument can be coerced to the Signature parameter type).

0.14.0-alpha - 2023-12-15

Added

  • Adds top-level IR node creation functions.
  • Adds componentN functions (destructuring) to IR nodes via Kotlin data classes
  • Adds public tag field to IR nodes for associating metadata
  • Adds AST Normalization Pass.
  • Adds PartiQLPlanner Interface, which is responsible for translate an AST to a Plan.
  • EXPERIMENTAL Evaluation of EXCLUDE in the EvaluatingCompiler
    • This is currently marked as experimental until the RFC is approved partiql/partiql-lang#27
    • This will be added to the PhysicalPlanCompiler in an upcoming release
  • EXPERIMENTAL: Adds support for EXCLUDE in the default SqlDialect.

Changed

  • StaticTypeInferencer and PlanTyper will not raise an error when an expression is inferred to NULL or unionOf(NULL, MISSING). In these cases the StaticTypeInferencer and PlanTyper will still raise the Problem Code ExpressionAlwaysReturnsNullOrMissing but the severity of the problem has been changed to warning. In the case an expression always returns MISSING, problem code ExpressionAlwaysReturnsMissing will be raised, which will have problem severity of error.
  • Breaking The default integer literal type is now 32-bit; if the literal can not fit in a 32-bit integer, it overflows to 64-bit.
  • BREAKING PartiQLValueType now distinguishes between Arbitrary Precision Decimal and Fixed Precision Decimal.
  • BREAKING Function Signature Changes. Now Function signature has two subclasses, Scalar and Aggregation.
  • BREAKING Plugin Changes. Only return one Connector.Factory, use Kotlin fields. JVM signature remains the same.
  • BREAKING In the produced plan:
    • The new plan is fully resolved and typed.
    • Operators will be converted to function call.
  • Changes the return type of filter_distinct to a list if input collection is list
  • Changes the PartiQLValue collections to implement Iterable rather than Sequence, allowing for multiple consumption.
  • BREAKING Moves PartiQLParserBuilder.standard().build() to be PartiQLParser.default().
  • BREAKING Changed modeling of EXCLUDE in partiql-ast

Deprecated

Fixed

  • Fixes the CLI hanging on invalid queries. See issue #1230.
  • Fixes Timestamp Type parsing issue. Previously Timestamp Type would get parsed to a Time type.
  • Fixes PIVOT parsing to assign the key and value as defined by spec section 14.
  • Fixes the physical plan compiler to return list when DISTINCT used with ORDER BY

Removed

  • Breaking Removed IR factory in favor of static top-level functions. Change Ast.foo() to foo()
  • Breaking Removed org.partiql.lang.planner.transforms.AstToPlan. Use org.partiql.planner.PartiQLPlanner.
  • Breaking Removed org.partiql.lang.planner.transforms.PartiQLSchemaInferencer. In order to achieve the same functionality, one would need to use the org.partiql.planner.PartiQLPlanner.
    • To get the inferred type of the query result, one can do: (plan.statement as Statement.Query).root.type

    • The Bitwise And Operator only works for integer operands.
    • The operator precedence may change based on the pending operator precedence RFC.
  • EXPERIMENTAL Adds EXCLUDE to parser, ast, plan, and plan schema inferencer

Fixed

  • Fixes typing of scalar subqueries in the PartiQLSchemaInferencer. Note that usage of SELECT * in subqueries is not fully supported. Please make sure to handle InferenceExceptions.

  • Adds support for CLI users to use CTRL-C to cancel long-running compilation/execution of queries

Fixed

  • Fix a bug in FilterScanToKeyLookup pass wherein it was rewriting primary key equality expressions with references to the candidate row on both sides. Now it will correctly ignore such expressions.
  • Fixes build failure for version 0.13.0 by publishing partiql-plan as an independent artifact. Please note that partiql-plan is experimental.

  • Adds org.partiql.value (experimental) package for reading/writing PartiQL values
  • Adds function overloading to the CompilerPipeline and experimental PartiQLCompilerPipeline.
  • Adds new method getFunctions() to org.partiql.spi.Plugin.
  • Adds PartiQLFunction interface.
  • Adds FunctionSignature and FunctionParameter class to org/partiql/types/function.
  • Adds a new flag --plugins to PartiQL CLI to allow users to specify the root of their plugins directory. The default is ~/.partiql/plugins . Each implementer of a plugin should place a directory under the plugins root containing the JAR corresponding with their plugin implementation. Example: ~/.partiql/plugins/customPlugin/customPlugin.jar
  • Adds serialization and deserialization between IonValue and org.partiql.value.
  • Adds org.partiql.ast package and usage documentation
  • Adds org.partiql.parser package and usage documentation
  • Adds PartiQL's Timestamp Data Model.
  • Adds support for Timestamp constructor call in Parser.
  • Parsing of label patterns within node and edge graph patterns now supports disjunction |, conjunction &, negation !, and grouping.
  • Adds default equals and hashCode methods for each generated abstract class of Sprout. This affects the generated classes in :partiql-ast and :partiql-plan.
  • Adds README to partiql-types package.
  • Initializes PartiQL's Code Coverage library
    • Adds support for BRANCH and BRANCH-CONDITION Coverage
    • Adds integration with JUnit5 for ease-of-use
    • For more information, see the "Writing PartiQL Unit Tests" article in our GitHub Wiki.
  • Adds new constructor parameters to all variants of PartiQLResult.
  • Adds two new methods to PartiQLResult: getCoverageData and getCoverageStructure.

Changed

  • Breaking: all product types defined by the internal Sprout tool no longer generate interfaces. They are now abstract classes due to the generation of equals and hashCode methods. This change impacts many generated interfaces exposed in :partiql-ast and :partiql-plan.
  • Standardizes org/partiql/cli/functions/QueryDDB and other built-in functions in org/partiql/lang/eval/builtins by the new ExprFunction format.
  • Breaking: Redefines org/partiql/lang/eval/ExprFunctionkt.call() method by only invoking callWithRequired function.
  • Breaking: Redefines org/partiql/lang/eval/builtins/DynamicLookupExprFunction by merging variadicParameter into requiredParameters as a StaticType.LIST. callWithVariadic is now replaced by callWithRequired.
  • Upgrades ion-java to 1.10.2.
  • Breaking (within experimental graph features): As part of extending the language of graph label patterns:
    • Changed the type of the field label in AST nodes org.partiql.lang.domains.PartiqlAst.GraphMatchPatternPart.{Node,Edge}, from SymbolPrimitive to new GraphLabelSpec.
    • Changed the names of subclasses of org.partiql.lang.graph.LabelSpec, from OneOf to Name, and from Whatever to Wildcard.
  • Breaking the package org.partiql.lang.errors has been moved to org.partiql.errors, moved classes include
    • org.partiql.lang.errors.ErrorCategory -> org.partiql.errors.ErrorCategory
    • org.partiql.lang.errors.Property -> org.partiql.errors.Property
    • org.partiql.lang.errors.PropertyValue -> org.partiql.errors.PropertyValue
    • org.partiql.lang.errors.PropertyType -> org.partiql.errors.PropertyType
    • org.partiql.lang.errors.PropertyValueMap -> org.partiql.errors.PropertyValueMap
    • org.partiql.lang.errors.ErrorCode -> org.partiql.errors.ErrorCode
    • org.partiql.lang.errors.Problem -> org.partiql.errors.Problem
    • org.partiql.lang.errors.ProblemDetails -> org.partiql.errors.ProblemDetails
    • org.partiql.lang.errors.ProblemSeverity -> org.partiql.errors.ProblemSeverity
    • org.partiql.lang.errors.ProblemHandler -> org.partiql.errors.ProblemHandler
  • Breaking the sourceLocation field of org.partiql.errors.Problem was changed from org.partiql.lang.ast.SoureceLocationMeta to org.partiql.errors.ProblemLocation.
  • Removed Nullable<Value implementations of PartiQLValue and made the standard implementations nullable.
  • Using PartiQLValueType requires optin; this was a miss from an earlier commit.
  • Breaking removed redundant ValueParameter from FunctionParameter as all parameters are values.
  • Introduces isNullCall and isNullable properties to FunctionSignature.
  • Removed Nullable...Value implementations of PartiQLValue and made the standard implementations nullable.
  • Using PartiQLValueType requires optin; this was a miss from an earlier commit.
  • Modified timestamp static type to model precision and time zone.

Deprecated

  • Breaking: Deprecates the Arguments, RequiredArgs, RequiredWithOptional, and RequiredWithVariadic classes, along with the callWithOptional(), callWithVariadic(), and the overloaded call() methods in the ExprFunction class, marking them with a Deprecation Level of ERROR. Now, it's recommended to use call(session: EvaluationSession, args: List<ExprValue>) and callWithRequired() instead.
  • Breaking: Deprecates optionalParameter and variadicParameter in the FunctionSignature with a Deprecation Level of ERROR. Please use multiple implementations of ExprFunction and use the LIST ExprValue to represent variadic parameters instead.

Fixed

Removed

  • Breaking: Removes optionalParameter and variadicParameter from org.partiql.lang.types.FunctionSignature. To continue support for evaluation of optionalParameters, please create another same-named function. To continue support for evaluation of variadicParameter, please use a StaticType.LIST to hold all previously variadic parameters. As this changes coincides with the addition of function overloading, only callWithRequired will be invoked upon execution of an ExprFunction. Note: Function overloading is now allowed, which is the reason for the removal of optionalParameter and variadicParameter.
  • Breaking: Removes unused class Arguments from org.partiql.lang.eval.
  • Breaking: Removes unused parameter args: Arguments from org.partiql.lang.eval.ExprFunctionkt.call() method.

0.12.0-alpha - 2023-06-14

Added

  • Adds support for using EXCLUDED within DML ON-CONFLICT-ACTION conditions. Closes #1111.

Changed

  • Updates Kotlin target from 1.4 (DEPRECATED) to 1.6
  • Moves PartiqlAst, PartiqlLogical, PartiqlLogicalResolved, and PartiqlPhysical (along with the transforms) to a new project, partiql-ast. These are still imported into partiql-lang with the api annotation. Therefore, no action is required to consume the migrated classes. However, this now gives consumers of the AST, Experimental Plans, Visitors, and VisitorTransforms the option of importing them directly using: org.partiql:partiql-ast:${VERSION}. The file partiql.ion is still published in the partiql-lang-kotlin JAR.
  • Moves internal class org.partiql.lang.syntax.PartiQLParser to org.partiql.lang.syntax.impl.PartiQLPigParser as we refactor for explicit API.
  • Moves ANTLR grammar to partiql-parser package. The files PartiQL.g4 and PartiQLTokens.g4 are still published in the partiql-lang-kotlin JAR.
  • Breaking: Adds new property, rowAlias, to experimental PartiqlLogical.DmlOperation.DmlUpdate, PartiqlLogical.DmlOperation.DmlReplace, PartiqlLogicalResolved.DmlOperation.DmlUpdate, PartiqlLogicalResolved.DmlOperation.DmlReplace, PartiqlPhysical.DmlOperation.DmlUpdate, and PartiqlPhysical.DmlOperation.DmlReplace.

0.11.0-alpha - 2023-05-22

Added

  • Adds an initial implementation of GPML (Graph Pattern Matching Language), following PartiQL RFC-0025 and RFC-0033. This initial implementation includes:
    • A file format for external graphs, defined as a schema in ISL (Ion Schema Language), as well as an in-memory graph data model and a reader for loading external graphs into it.
    • CLI shell commands !add_graph and !add_graph_from_file for bringing externally-defined graphs into the evaluation environment.
    • Evaluation of straight-path patterns with simple label matching and all directed/undirected edge patterns.
  • Adds new TupleConstraint variant, Ordered, to represent ordering in StructType. See the KDoc for more information.

Changed

  • Breaking: The fields attribute of org.partiql.types.StructType is no longer a Map<String, StaticType>. It is now a List<org.partiql.types.StructType.Field>, where Field contains a key (String) and value (StaticType). This is to allow duplicates within the StructType.

Deprecated

Fixed

  • Fixes the ability for JOIN predicates to access the FROM source aliases and corresponding attributes.

0.10.0-alpha - 2023-05-05

Added

  • Added numeric builtins ABS, SQRT, EXP, LN, POW, MOD.
  • Added standard SQL built-in functions POSITION, OVERLAY, LENGTH, BIT_LENGTH, OCTET_LENGTH, CARDINALITY, an additional builtin TEXT_REPLACE, and standard SQL aggregations on booleans EVERY, ANY, SOME.
  • Breaking Added coercion of SQL-style subquery to a single value, as defined in SQL for subqueries occurring in a single-value context and outlined in Chapter 9 of the PartiQL specification. This is backward incompatible with the prior behavior (which left the computed collection as is), but brings it in conformance with the specification.
  • Added partiql-plan package which contains experimental PartiQL Plan data structures.
  • Initializes SPI Framework under partiql-spi.
  • Models experimental Schema with constraints. With this change, we're introducing Tuple and Collection constraints to be able to model the shape of data as constraints.
  • Introduces the PartiQLSchemaInferencer and PlannerSession
    • The PlannerSession describes the current session and is used by the PartiQLSchemaInferencer.
    • The PartiQLSchemaInferencer provides a function, infer, to aid in inferring the output StaticType of a PartiQL Query. See the KDoc for more information and examples.
  • Adds back ability to convert an IonDatagram to an ExprValue using of(value: IonValue): ExprValue and newFromIonValue(value: IonValue): ExprValue
  • Adds support for SQL's CURRENT_USER in the AST, EvaluatingCompiler, experimental planner implementation, and Schema Inferencer.
    • Adds the AST node session_attribute.
    • Adds the function EvaluationSession.Builder::user() to add the CURRENT_USER to the EvaluationSession
  • Adds support for parsing and planning of INSERT INTO .. AS <alias> ... ON CONFLICT DO [UPDATE|REPLACE] EXCLUDED WHERE <expr>
  • Adds the statement.dml and dml_operation node to the experimental PartiQL Physical Plan.

Changed

  • Deprecates the project level opt-in annotation PartiQLExperimental and split it into feature level. ExperimentalPartiQLCompilerPipeline and ExperimentalWindowFunctions.
  • Breaking: Moves StaticType to partiql-types.
    • All references to static types need to modify their imports accordingly. For example, org.partiql.lang.types.IntType is now org.partiql.types.IntType.
    • Please modify existing dependencies accordingly. You may need to add dependency org.partiql:partiql-types:0.10.0.
    • Also, several methods within StaticType have been moved to a utility class within partiql-lang-kotln. See the below list:

  • README.md badges for GitHub Actions status, codecov, and license
  • An experimental (pending #15) embedding of a subset of the GPML (Graph Pattern Matching Language) graph query, as a new expression form <expr> MATCH <gpml_pattern>, which can be used as a bag-of-structs data source in the FROM clause.
    The use within the grammar is based on the assumption of a new graph data type being added to the specification of data types within PartiQL, and should be considered experimental until the semantics of the graph data type are specified.

Experimental Planner Additions

  • Renamed PassResult to PlannerPassResult for clarity. (This is part of the experimental query planner API.)
  • The PlannerPipeline API now has experimental and partial support for INSERT and DELETE DML statements— tracking PartiQL specification issues are partiql-docs/#4 (only a subset has been implemented--see examples below) and partiql-docs/#19.
    • Examples of supported statements include:
      • INSERT INTO foo << { 'id': 1, 'name': 'bob' }, { 'id': 2, 'name' : 'sue' } >> (multi record insert)
      • INSERT INTO foo SELECT c.id, c.name FROM customer AS c (insert the results of a query into another table)
      • DELETE FROM foo (delete all records in a table)
      • DELETE FROM foo AS f WHERE f.zipCode = '90210' (delete all records matching a predicate)
  • Introduced planner event callbacks as a means to provide a facility that allows the query to be visualized at every stage in the PlannerPipeline and to generate performance metrics for the individual phases of query planning. See PlannerPipe.Builder.plannerEventCallback for details.
  • Adds the following optimization passes, none of which are enabled by default:
    • FilterScanToKeyLookupPass which performs a simple optimization common to most databases: it converts a filter predicate covering a table's complete primary key into a single get-by-key operation, thereby avoiding a full table scan. This may pass leave behind some useless and expressions if more and operands exist in the filter predicate other than primary key field equality expressions.
    • RemoveUselessAndsPass, which removes any useless and expressions introduced by the previous pass or by the query author, e.g. true and x.id = 42 -> x.id = 42), true and true -> true, etc.
    • RemoveUselessFiltersPass, which removes useless filters introduced by the previous pass or by the query author (e.g. (filter (lit true) <bexpr>)) -> <bexpr>.
  • Add support for UNPIVOT, the behavior is expected to be compatible with the evaluating compiler.
  • Adds support for GROUP BY (aggregations, group keys, etc)
  • Adds support for ORDER BY in Planner

Changed

  • The default parser for all components of PartiQL is now the PartiQLParser -- see the deprecation of SqlParser
  • Parsing of ORDER BY clauses will no longer populate the AST with defaults for the 'sort specification' (i.e., ASC or DESC) or 'nulls specification' (i.e., NULLS FIRST or NULLS LAST) when the are not provided in the query text. Defaulting of sort order is moved to the evaluator.

Deprecated

  • Deprecates SqlLexer and SqlParser to be replaced with the PartiQLParserBuilder.
  • Deprecates helper method, blacklist, within org.partiql.lang.eval and introduced a functionally equivalent org.partiql.lang.eval.denyList method.
  • Deprecates TypedOpParameter.LEGACY to be replaced with TypedOpParameter.HONOR_PARAMETERS

Fixed

  • Codecov report uploads in GitHub Actions workflow
  • GitHub Actions capability to run on forks
  • Negation overflow caused by minimum INT8
  • Type mismatch error caused by evaluator's integer overflow check
  • Cast function's behavior on positive_infinity, negative_infinity, and NaN explicitly defined and handled.
