The sstableofflinerelevel utility will relevel SSTables.
This tool is intended to run in an offline fashion. When using the
LevelledCompactionStrategy, it is possible for the number of
SSTables in level L0 to become excessively large, resulting in read latency
degrading. This is often the case when atypical write load is experienced (eg. bulk
import of data, node bootstrapping). This tool will relevel the SSTables in an
optimal fashion. The
--dry run flag can be used to run in test mode
and examine the tools results.
