questdb/questdb最新发布版本:7.4.2(2024-04-22 23:13:35)

Overview

Thanks for all who contributed to our most recent release.

This release provides a set of stability fixes and usability improvements.

We are excited to highlight the following areas:

Improved operations: A trio of features including improved snapshots to replace existing backup functionality, connection count gauge metrics and a new mkdir.mode for detached partitions make QuestDB easier to operate.
InfluxDB Line Protocol improvements: The InfluxDB Line Protocol is commonly used for rapid ingest. We’ve made it better, by introducing more flexible and less error prone timestamps. In addition, it also authenticates faster and disconnects on error when using WAL tables.
New aggregate functions: Thanks to community member @charlespnh QuestDB now offers variance(), var_samp() and var_pop(), stddev(), stddev_pop() functions.
