Release for ZIO 2.0.0
Virgil now supports ZIO 2.0
- Underlying Cassandra metrics have been exposed (Thanks to @narma)
Expose metrics [zio1]
Thanks to @narma for exposing metrics
Add stripMargin to CqlInterpolatedString
We've added stripMargin
which only works on the string portions of the cql query
val query =
cql"""SELECT id, name, persons
|FROM persons
|WHERE id = ${1} AND name = ${"cal"}""".stripMargin
// SELECT id, name, persons
// FROM persons
// WHERE id = :param0 AND name = :param1

Bugfix for ZIO 2
Fixes the counter syntax and a CQL rendering bug pertaining to counter columns.
Here's some example usage
UpdateBuilder(tableName).set(Likes += in.likes).where(Id === in.id).build

ZIO 2.0.0-RC6 support
select

s to reduce allocations and improve performance- users of the API get better error information thanks to making use of

Scala 3
Virgil now has support for Scala 3. Codecs only have semi-automatic derivation but we'll get there 😸
final case class CursorExampleRow(
id: Long,
name: String,
age: Short,
@CqlColumn("may_be_empty") mayBeEmpty: Option[String],
@CqlColumn("addresses") pastAddresses: Chunk[CursorUdtAddress]
)
object CursorExampleRow {
given cqlRowDecoderForCursorExampleRow: CqlRowDecoder.Object[CursorExampleRow] =
CqlRowDecoder.derive[CursorExampleRow]
val tableName = "cursorspec_cursorexampletable"
def truncate: CQL[MutationResult] = CQL.truncate(tableName)
def insert(row: CursorExampleRow): CQL[MutationResult] =
InsertBuilder(tableName)
.values(
"id" -> row.id,
"name" -> row.name,
"age" -> row.age,
"addresses" -> row.pastAddresses,
"may_be_empty" -> row.mayBeEmpty
)
.build
def select(id: Long): CQL[Row] = {
val cql = cql"SELECT * FROM " ++ tableName.asCql ++ cql" WHERE id = $id"
cql.query
}
}
final case class CursorUdtAddress(street: String, city: String, state: String, zip: String, note: CursorUdtNote)
object CursorUdtAddress {
given cqlUdtValueDecoderForCursorUdtAddress: CqlUdtValueDecoder.Object[CursorUdtAddress] =
CqlUdtValueDecoder.derive[CursorUdtAddress]
given cqlUdtValueEncoderForCursorUdtAddress: CqlUdtValueEncoder.Object[CursorUdtAddress] =
CqlUdtValueEncoder.derive[CursorUdtAddress]

CqlUdtValueEncoder.derive[CursorUdtNote]
}
ZIO 2.0 RC5 support
This release supports the latesrt version of ZIO 2.0 which is RC5 at the time. ZManaged and Has are deleted and we exclusively rely on Scopes to manage resources (like CqlSession and CQLExecutor).
Critical codec bugfix for Cassandra collections
Fixed a critical bug in codecs which treated empty Cassandra collections as an error since there is aggressive null checking. However, Cassandra does not actually have the concept of nullable collections like they do with their other datatypes. They store empty collections using null which is a bit confusing. So we changed the behavior of the codecs to account for this fact. So now you can do this:
Given a Cassandra table
CREATE TABLE example (
id INT PRIMARY KEY,
data set<ascii>
);
final case class Example(
@CqlColumn("id") id: Int,
@CqlColumn("data") data: Set[String]
)
val insert =
InsertBuilder("example")
.values(
"id" -> 2,
"data" -> Set.empty[String]
)
.build
.executeMutation
val select =
SelectBuilder
.from("example")
.allColumns
.build[Example]
.execute
.runCollect
This will correctly return empty Set values. The same is true when using the Cursor API.
🔴 Please keep in mind if you wrap Cassandra collections in Option
, you'll get the equivalent of having Option[NonEmptyCollection]
behavior in that you will either have a None
if you persist an empty collection or a populated collection would appear as Some(List(1))
as an example.
