v2.3.18

Release date: June 18, 2024

Milvus v2.3.18 includes several bug fixes and improvements to enhance query result quality and maintainability. This release also backports improvements and fixes from the 2.4 branch, which enhance control over delete data amounts (according to rate limit configuration) and increase Bloom filter processing speed. As with previous releases, this update reinforces Milvus's commitment to functionality and robustness.

Improvements

• Added RESTful APIs to trigger component stop (#33798).
• Improved delete by expression to respect delete rate limit rules according to the matched data size instead of delete request size (#33794).
• Accelerated Bloom filter processing by submitting in batch and working in parallel (#33870).
• Enabled parallel processing for applydelete at the segment level (#33841).
• Printed UseDefaultConsistency parameter in read requests (#33645).

Bug fixes

• Fixed a bug where closure capture iteration variable caused delete data to fail to apply to the correct data (#33912).
• Fixed a bug where filtered results could be less than topk by upgrading Knowhere to 2.2.10 (#33930).
• Fixed a bug where insert rate was not limited when collection.insertrate.max.mb config was set to 0 (#33725).
• Fixed a bug where old collections created before v2.2.8 could reappear and become zombies after being dropped and restarted (#33695).
• Fixed a bug where upsert latency used the wrong unit, causing abnormal metrics (#33580).
• Fixed a bug where Milvus exception info could not be passed outside of segcore (#33395).
