sstableofflinerelevel

Relevels SSTables offline.

This tool runs offline. When using the LevelledCompactionStrategy, the number of SSTables in level L0 can become excessively large, degrading the read latency. This often occurs during an atypical write load, such as bulk import of data and node bootstrapping. This tool optimally relevels the SSTables. Use the --dry run flag to run in test mode and examine the tools results.

Usage:

sstableofflinerelevel [--dry-run] keyspace table

Tarball and Installer No-Services path:

installation_location/resources/cassandra/tools/bin

Procedure

Choose a keyspace and table to relevel.
