Synopsis

nodetool <options> getsstables [(-hf | --hex-format)] -- <keyspace> <table> <key>

Table 1. Options
Short	Long	Description
`-h`	`--host`	Hostname or IP address.
`-p`	`--port`	Port number.
`-pwf`	`--password-file`	Password file path.
`-pw`	`--password`	Password.
`-u`	`--username`	Remote JMX agent username.
`keyspace`	Name of keyspace.
`table`	One or more table names, separated by a space.
`key`	Partition key of the SSTables.
`--`	Separates an option from an argument that could be mistaken for a option.

Description

This command can be used to retrieve an SSTable.

Examples

An example of this command retrieves the SSTable for cycling.cyclist_name with the key argument fb372533-eb95-4bb4-8685-6ef61e994caa for one of the cyclists listed:

nodetool getsstables cycling cyclist_name 'fb372533-eb95-4bb4-8685-6ef61e994caa'

The output is:

/homedir/datastax-ddc-3.6.0/data/data/cycling/cyclist_name-612a64002ec211e6a92457e568fce26f/ma-1-big-Data.db

Sometimes it's useful to retrieve an SSTable from the hex string representation of its key, for instance, when you get this exception and you want to find out which SSTable owns the faulty key:

java.lang.AssertionError: row DecoratedKey(2769066505137675224, 00040000002e00000800000153441a3ef000) received out of order wrt DecoratedKey(2774747040849866654, 00040000019b0000080000015348847eb200)

The nodetool getsstables command will only work if the primary key of the given table is a blob.

nodetool getsstables keyspace table 00040000002e00000800000153441a3ef000

For such cases in Cassandra 3.6 and later, the option --hex-key can be used to retrieve the DecoratedKey from the hexstr representation of the key:

nodetool getsstables ks cf --hex-key 00040000002e00000800000153441a3ef000
