sstablelevelreset

Resets the level to zero on a set of SSTables.

Reset level to zero on a set of SSTables using LeveledCompactionStrategy.

Usage:

sstablelevelreset [--really-reset] keyspace table

The option --really-reset is a warning that DataStax Enterprise (DSE) is stopped before the tool is run.

Tarball and Installer No-Services path:

installation_location/resources/cassandra/tools/bin

Procedure

Stop DSE on the node. Choose a keyspace and table to reset to level 0.

sstablelevelreset --really-reset cycling cyclist_name

If the designated table is already at level 0, then no change occurs. If the SSTable is releveled, the metadata is rewritten to designate the level to 0.
