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:
