OPEN DATA DAY 2024 Release! 🎉🎉🎉

In celebration of Open Data Day, we're releasing qsv 0.123.0 - the biggest release ever with 330+ commits! qsv 0.123.0 continues to focus on performance, stability and reliability as we continue setting the stage for qsv's big brother - qsv pro.

We've been baking qsv pro for a while now, and it's almost ready for release. qsv pro is a cross-platform Desktop Data Wrangling tool marrying an Excel-like UI with the power of qsv, backed by cloud-based data cleaning, enrichment and enhancement service that's easy to use for casual Excel users and Data Publishers, yet powerful enough for data scientists and data engineers.

Stay tuned!

Highlights:

# with fast path optimization turned off

# with fast path optimization, fully exploiting Polars' multithreaded, mem-mapped CSV reader!
 /usr/bin/time qsv sqlp taxi.csv "select VendorID,sum(total_amount) from taxi group by VendorID order by VendorID"

/usr/bin/time csvq "select VendorID,sum(total_amount) from taxi group by VendorID order by VendorID"

"Traditional" SQL engines

qsv and csvq both operate on "bare" CSVs. For comparison, let's contrast qsv's performance against "traditional" SQL engines
that require setup and import (aka ETL). Not counting setup and import time (which alone, takes several minutes), we get:

sqlite3.43.2 takes 2.910 seconds - 20.79x slower

sqlite> .timer on
sqlite> select VendorID,sum(total_amount) from taxi group by VendorID order by VendorID;
1,52377417.53
2,89959869.13
4,600584.61
Run Time: real 2.910 user 2.569494 sys 0.272972

PostgreSQL 15.6 using PgAdmin 4 v6.12 takes 18.527 seconds - 132.34x slower

even with an index, qsv sqlp is still 5.96x faster

  • sqlp now supports JSONL output format and adds compression support for Avro and Arrow output formats.
  • fetch now has a --disk-cache option, so you can cache web service responses to disk, complete with cache control and expiry handling!
  • jsonl is now multithreaded with additional --batch and --job options.
  • split now has three modes: split by record count, split by number of chunks and split by file size.
  • datefmt is a new top-level command for date formatting. We extracted it from apply to make it easier to use, and to set the stage for expanded date and timezone handling.
  • enum now has a --start option.
  • excel now has a --keep-zero-time option and now has improved datetime/duration parsing/handling with upgrade of calamine from 0.23 to 0.24.
  • tojsonl now has --trim and --no-boolean options and eliminated false positive boolean inferences.
