This short report brings to light some interesting commits to [scylladb.git master](https://github.com/scylladb/scylladb/) from the last week. Commits in the 5eadea301e…61dfc9c10f range are covered.

There were 64 non-merge commits from 16 authors in that period. Some notable commits:

  

Raft topology now [verifies](https://github.com/scylladb/scylladb/commit/fa9cf81af28af58ecf23d6a2d42d7b1c4ce727c7) that the gossip view of the token ring matches the raft view.

Yet another locking race in the materialized view update path was [fixed](https://github.com/scylladb/scylladb/commit/5d914adcef1f206b684cf4cdfdcbfb0ebd227665).

A size-on-disk accounting bug in commitlog was [fixed](https://github.com/scylladb/scylladb/commit/fa7e904cd6e55f67c360c49fc4910fc517757bbb). This could lead to segment recycling being stopped indefinitely, with a large reduction in write performance.

A bug which could cause crashes while reporting errors in invalid CQL statements involving field selection from a user-defined type was [fixed](https://github.com/scylladb/scylladb/commit/186ceea009fe36b401cff7cbbc2ed16512d72318).

The compaction backlog tracker computes the amount of work remaining for compaction. It is updated when inserting sstables into the table. The efficiency of this process, for leveled compaction strategy tables, was [improved](https://github.com/scylladb/scylladb/commit/1b2140e416fbb7b1f2a09268825909d07653017c).

io\_uring support was [disabled](https://github.com/scylladb/scylladb/commit/53366db6c66798808143b1e3170f2bb6dbcae5f6), since it appears to cause regressions.

ScyllaDB is now more [careful](https://github.com/scylladb/scylladb/commit/86c61828e65eb2b300b51103e83751c92b1021fd) which dropping user-defined types that are used by a user-defined function.

Out-of-memory management can halt allocations from all but one query, in order to get that query to complete and release memory. However, if that query was paused, it could deadlock the system. This is now [fixed](https://github.com/scylladb/scylladb/commit/34cdcaffaee27e07963a6026c7799e03c50cac8f).

  

See you in the next issue of last week in scylladb.git master!
