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 e7d6ab576b…39b55bd3a0 range are covered.

There were 118 non-merge commits from 20 authors in that period. Some notable commits:

  

`nodetool compactionhistory` will now report statistics about [rows merged](https://github.com/scylladb/scylladb/commit/3124711fc450ee7301c345a968661011a319fcc4) during compaction.

The bundled node\_exporter Prometheus integration now [disables temperature monitoring](https://github.com/scylladb/scylladb/commit/850d9cfb59364e5d705752799455cce2b9219b51), as it causes bad performance on Azure.

`nodetool status` now shows [nodes with no tokens](https://github.com/scylladb/scylladb/commit/101c1d50f0d046134d0fbf9678b86a6055bec163).

The efficiency of sstable reads rows within medium or large partitions, when column\_index\_size\_in\_kb has been reduced, is now [improved](https://github.com/scylladb/scylladb/commit/94c21e5c05109014673ef3c7d6eaf3df556b48ff). Such reads will generate less I/O.

ScyllaDB tracks whether read requests are waiting for CPU or I/O. In one case, a disk read from the primary index was considered to be waiting on CPU, which reduced concurrency. This is now [fixed](https://github.com/scylladb/scylladb/commit/020ccbd76a134ed9642480a36fa15b4e902f30b6).

The CREATE ROLE USING SALTED HASH statement was [renamed](https://github.com/scylladb/scylladb/commit/b9844885527a2e7341444f2401e18a948022d53e) to CREATE ROLE USING HASHED PASSWORD for improved compatibility with Cassandra.

Materialized view building (initiated by CREATE MATERIALIZED VIEW or CREATE INDEX) is now [performance-isolated](https://github.com/scylladb/scylladb/commit/88ab8db94428e8289159dd6e7a526630c77075ca) from normal reads and writes.

The REST API now reports [progress of backup tasks](https://github.com/scylladb/scylladb/commit/0ee0dd3ef45781a13001fb271acf82688196ea27).

Repair flushes hints and batchlog in order to reduce the amount of work it has to do, but such flushes also generate work, so these flushes are now [batched](https://github.com/scylladb/scylladb/commit/19a43b58599c72acd98947a335999b84bbd0e4eb).

  

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