Bumps org.questdb:questdb from 7.3.9 to 8.1.2.

Release notes

Sourced from org.questdb:questdb's releases.

8.1.2

October has arrived, and with it the fall. According to an interesting character, it's also Libra ♎ season, a phase of balance. It works for us, as this release restores the balance within QuestDB's production reliability. Chasing maximum performance and cutting-edge features is our favourite game. But every now and then, it's essential to double-back and smooth out the edges so that the overall experience presents consistent excellence. And, well, we'll keep improving performance too.

Download, upgrade, and prepare for the seasonal feasts. 🎃

Breaking Changes 💥

• Logging level adjustments: Some log messages previously logged at the INFO level have been changed to DEBUG. This reduction in log verbosity may impact monitoring systems relying on these messages. Adjust logging configurations as necessary.

New features 🐣

• Web Console UI tabs: The QuestDB Web Console features tabs for better query management. Tabs are archived upon closing and can be brought back from the history section as needed.

• ILP client row cancellation: The ILP client now supports cancelling the current row during data ingestion. This allows for greater control when writing data and helps prevent incomplete or erroneous data from being committed.

• New financial function spread_bps: Computes the spread in basis points between two numerical values.

• greatest and least functions: Determine the maximum or minimum value from a list of expressions. These functions simplify comparisons across multiple columns or expressions.

• Interval functions for date filters: Implemented new interval functions today(), tomorrow(), and yesterday() that return intervals representing the entire day. These functions make it easier to filter queries based on whole-day periods without manually specifying time ranges.

• New aggregate function string_distinct_agg: Aggregates unique string values into a single, concatenated string with a specified delimiter. This is useful for creating summaries of distinct values in a dataset.

• ILP traffic to Prometheus: Introduced metrics to monitor ILP (Influx Line Protocol) traffic volumes over both TCP and HTTP. These metrics help in tracking data ingestion rates and diagnosing network-related issues.

• RedHat OpenShift Compatible Docker Image: Beginning with this release, QuestDB Docker images with a -rhel suffix are now compatible with RedHat's OpenShift container orchestration platform.

New integrations

• Bento by Warpstream Labs: In the words of Bento they provide: Fancy stream processing made operationally mundane. Indeed, and now even fancier with a fresh QuestDB component.

• Redpanda Connect: Formerly Benthos. Comes with a QuestDB output component that can be used as a sink for your stream processing data. Read our docs for more information.

Performance improvements 🚀

• Static metadata cache: Implemented a static metadata cache to improve performance by reducing the overhead associated with frequent metadata access. This enhancement speeds up query compilation and execution.

• Optimized partition reloads: Reduced unnecessary reloads of TableReader partitions, which enhances query performance, especially in environments with high data ingestion rates and frequent queries.

• Improved parallel GROUP BY execution: Optimized parallel GROUP BY operations by eliminating redundant bytecode generation. This results in faster execution times for complex aggregation queries.

• Faster Web Console queries: You'll notice improved performance during the highligh and execution of queries with SQL comments in the editor.

Improvements 🛠️

• Enhanced log compatibility: Added a configuration option to control verbose log levels, improving compatibility with log readers and monitoring tools that require specific log formats or verbosity levels.

• Detailed ILP error messages: Enhanced the server logs to include specific error messages indicating the exact line that caused a receive buffer overflow during ILP ingestion. This aids in troubleshooting and correcting data formatting issues.
