Description
This command can be used to retrieve an SSTable.
Examples
The following example of this command retrieves the SSTable for cycling.cyclist_name
with the key argument fb372533-eb95-4bb4-8685-6ef61e994caa
, which is the id
for one of the cyclists listed in the cyclist_name
table:
nodetool getsstables cycling cyclist_name 'fb372533-eb95-4bb4-8685-6ef61e994caa'
The output is:
/var/lib/cassandra/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_name 00040000002e00000800000153441a3ef000
Use the --hex-key
option to retrieve the DecoratedKey
from the hexstr representation of the key:
nodetool getsstables ks cf --hex-key 00040000002e00000800000153441a3ef000
