Last week in scylla.git master (issue #122; 2022-03-27)

[Avi Kivity]

This short report brings to light some interesting commits to scylla.git master from the last weeks. Commits in the cd5fec8a2..1feec08c2d range are covered.

There were 30 non-merge commits from 13 authors in that period. Some notable commits:

Cleanup compactions, used after bootstrapping a new node to reclaim space in the original nodes, now have reduced write amplification.

Sstable index file reads now use read-ahead. This improves performance in workload that frequently skip over small parts of the partition (e.g. full scans with clustering key restrictions).

When Scylla generates a name for a secondary index, it will avoid using special characters (if they were present in the table name).

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