v.25.6Experimental Feature

Update on-fly by reading and writing

Official CH changelog text
Previously, packed storage was not supported for the full-text index, because the segment id was updated on-fly by reading and writing (.gin_sid) file on disk. In case of packed storage, reading a value from the uncommited file is not supported and this led to an issue. Now it is alright. #80852 (Elmi Ahmadov).
Support for packed storage in full-text index. Previously, full-text indexes did not support packed storage due to on-the-fly segment ID updates using .gin_sid file reads and writes. This limitation has been resolved.

Why it matters

The feature addresses the issue where reading segment IDs from uncommitted files was unsupported in packed storage, preventing full-text indexes from working correctly with this storage format. By enabling support for packed storage, users can now benefit from efficient full-text indexing alongside optimized storage.

How to use it

Users can now use full-text indexes on tables with packed storage without additional configuration. This support is automatic once the version including this fix is used.
