sstablesplit

Use this tool to split SSTables files into multiple SSTables of a maximum designated size.

Use this tool to split SSTables files into multiple SSTables of a maximum designated size. For example, if SizeTieredCompactionStrategy was used for a major compaction and results in a excessively large SSTable, it's a good idea to split the table because won't get compacted again until the next huge compaction.

Cassandra must be stopped to use this tool:

Cassandra package installations:
```
sudo service cassandra stop
```
Cassandra tarball installations:
```
ps auwx | grep cassandra
```

Usage:

Cassandra package installations:

sstablesplit [options] <filename> [<filename>]*

Cassandra tarball installations:

cd install_location
$ bin/sstablesplit [options] <filename> [<filename>]*

Example:

sstablesplit -s 40 /var/lib/cassandra/data/data/Keyspace1/Standard1/*
