v0.5.0

New feature: tombsweeper

The main new feature in the release is the 'tombsweeper'. When a record is deleted in a Lightning Stream installation, we do not actually remove the record, but instead write a deletion marker. Up until now these deletion markers were never deleted, leading to unbounded database growth in installations that see delete-heavy workloads. The new tombsweeper can clean these deletion markers after a configured interval.

WARNING: This is DISABLED by default, because enabling this functionality requires careful consideration. When enabled, you MUST make sure that no instance that has been offline for longer than the sweeper retention_days will ever reconnect. If this does happen, old entries that have been deleted may be resurrected causing anything from undesired results to database state corruption. Be especially careful about development or testing systems that only come online occasionally.

For small personal installations with infrequent changes, it is probably better NOT to enable this functionality, and accept that deleted entries accumulate over time. Only consider this you have frequent updates and deletion markers would actually become a problem over time. And in that case, be very conservative with the retention_days setting, the longer the better.

Full Changelog: v0.4.1...v0.4.2

v0.4.1

This fixes a resource leak that can cause growing memory and CPU usage over time (#57) for all S3 backend users.

It also fixes the update marker not working when a global S3 prefix is used, which causes the backend to use more expensive LIST API calls, leading to increased S3 usage costs. (#55)
This only affects you if you are using the opt-in upgrade marker.

What's Changed

• Upgrade Simpleblob to v0.2.4 by @franklouwers in #58

New Contributors

• @franklouwers made their first contribution in #58, thank you!
