Release date: January 04, 2025
This version fixes the following critical issues:
- Automatic alteration of the table may lead to inconsistent metadata.
- Compaction doesn't use files in the local cache.
Notes
This version modifies the default object storage cache paths:
- The path for write cache has changed from the default
{data_home}/object_cache/write to {data_home}/cache/object/write.
- The path for read cache has changed from the default
{data_home}/object_cache/read to {data_home}/cache/object/read.
- When configuring write cache and read cache, only the root directory of the cache needs to be specified, which defaults to
{data_home}.
We recommend that users no longer manually configure the cache paths after version 0.11, as the database can automatically set appropriate paths.
