Bumps org.questdb:questdb from 7.3.9 to 7.4.2.

Release notes

Sourced from org.questdb:questdb's releases.

7.4.2

Choice is essential. But isn't it nice when a clear, happy path emerges?

To that tune, we're pleased to announce QuestDB 7.4.2, with the usual mix of features, fixes and improvements.

In focus this week is the refinement of our updated ingestion clients. Built atop the InfluxDB Line Protocol (ILP) and leveraging HTTP instead of TCP, our clients and core database now offer a primary ingestion path that is robust, responsive and fast. They're available in popular languages, including Rust, Python, Java, Go, C & C++, and more.

It is quicker, cleaner and clearer to both get started and refine.

New Features 🐣

Fresh goods.

• Added bind variable support for long256 and IPv4 operators, milliseconds and microseconds support to datediff and dateadd.

• Enabled FILL(LINEAR) to support ALIGN TO CALENDAR.

Performance 🚀

Always a category unto its own.

• ILP: Optimized data ingestion for tables with a large number of columns.

• Core: Improved hash table lookup for small string keys and optimized memory usage to reduce OS kills.

• SQL: Faster SQL COPY and REST API CSV import, optimized binary search corner cases, and fixed the stuck parallel GROUP BY queries via better query timeout handling.

Bug Fixes 🥾

Squished, squashed & kiboshed.

• ILP: Addressed 'maximum buffer size exceeded' in ILP client and made config adjustments to disable individual flush types and support auto_flush_bytes. also corrected client processing of data received before TLS close_notification.

• SQL: Fixed incorrect results from lower, upper, substring functions when executed in parallel, erroneous SAMPLE BY behavior mixing asterisks, errors in CASE statements when ELSE branch is missing, incorrect results in GROUP BY queries, and SAMPLE BY queries with functions in the SELECT clause.

  Also fixed a bug for negative upper bound in BETWEEN operator, issues with null string insertions as designated timestamps, and inaccurate double comparisons. Finally, resolved stuck parallel group by queries due to incorrect timeout handling.

• Core: Addressed a rare segmentation fault during o3 commit of a non-WAL table, potential error rebuilding nascent data index, and incorrect partition size after an update.

New Contributors 🎉

@​hoangsvit and @​sivukhin made their first contributions. Thanks, both of you. 🙏
