(iggy) 01/01: fix(server): segments inherit topic's message_expiry instead of server default
This is an automated email from the ASF dual-hosted git repository.
hgruszecki pushed a commit to branch messages-cleaner
in repository https://gitbox.apache.org/repos/asf/iggy.git
commit ca58daba2837ae9c8f7a6242c453b091d4ebefb9
Author: Hubert Gruszecki <h....@gmail.com>
AuthorDate: Thu Jan 29 19:11:28 2026 +0100
fix(server): segments inherit topic's message_expiry instead of server default
Segments created after server startup were using the server's
default message_expiry (NeverExpire) rather than the topic's
configured value, causing messages to never be cleaned up even
when expiry was set.
- Propagate topic's message_expiry to all segment creation sites
- Move message_expiry config from [system.segment] to [system.topic]
- Remove delete_oldest_segments toggle
- Seal segments on rotation so is_expired() can evaluate them
- Add comprehensive tests for time-based, size-based, and combined
Closes #2629.
