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

Usage:

install_location/tools/bin/sstablelevelreset [--really-reset] keyspace table

The option --really-reset is a warning that the DataStax Distribution of Apache Cassandra™ (DDAC) is stopped before the tool is run.

Procedure

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

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.
