Last week in scylladb.git master (issue #141; 2022-08-07)

[Avi Kivity]

This short report brings to light some interesting commits to scylladb.git master from the last weeks. Commits in the cf47db2bdb..7f80602b01 range are covered.

There were 146 non-merge commits from 18 authors in that period. Some notable commits:

The master branch is now marked as belonging to the 5.2 release stream, indicating that 5.1 has been branched.

An automatically parallelized aggregation query now limits the number of token ranges it sends to a remote node in a single request, in order to reduce large allocations.

A compiled WebAssembly function will now be reused across multiple invocations. Creating a WebAssembly function instance is very expensive, so we amortize the creation across many invocations.

The sstable tools gained a write operation that can convert a json dump of an sstable back into an sstable.

Accidentally quadratic behavior when a large number of range tombstones is present in a partition has been fixed.

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