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:

C:\> net stop DataStax_Cassandra_Community_Server

C:\> net stop DataStax_DDC_Server

Usage:

C:\> cd "Program Files\DataStax Community\apache-cassandra\tools\bin"
C:\> sstablesplit [options] <filename> [<filename>]*

C:\>
                    Program Files\DataStax Community\apache-cassandra\tools\bin\sstablesplit
                    [options] <filename> [<filename>]*

Example:

C:\> sstablesplit -s 40 "Program Files\DataStax Community \data\data\Keyspace1\Standard1\*"

Options
