Nodetool restore¶

restore - Load SSTables from a designated bucket in object store into a specified keyspace or table

Note that status of restore can be checked for user_task_ttl seconds after the operation is done. You can set the ttl using nodetool tasks user-ttl. If --nowait flag is not set, the command relies on user_task_ttl internally.

Syntax¶

nodetool [(-h <host> | --host <host>)] [(-p <port> | --port <port>)]
            --endpoint <endpoint> --bucket <bucket>
            --prefix <prefix>
            --keyspace <keyspace>
            --table <table>
            [--nowait]
            [--scope <scope>]
            <sstables>...

Example¶

nodetool restore --endpoint s3.us-east-2.amazonaws.com  --bucket bucket-foo --prefix ks/cf/24601 --keyspace ks --table cf \

  scylla/ks/cf/42/me-3gdq_0bki_2s3e829t3gyq994yjl-big-TOC.txt

Options¶

  • -h <host> or --host <host> - Node hostname or IP address.

  • --endpoint - Name of the configured object storage endpoint to load SSTables from. This should be configured as per the object storage configuration instructions.

  • --bucket - Name of the bucket to load SSTables from

  • --prefix - The share prefix for object keys of backed up SSTables

  • --keyspace - Name of the keyspace to load SSTables into

  • --table - Name of the table to load SSTables into

  • --nowait - Don’t wait on the restore process

  • --scope <scope> - Use specified load-and-stream scope

  • <sstables> - Remainder of keys of the TOC (Table of Contents) components of SSTables to restore, relative to the specified prefix

The scope parameter describes the subset of cluster nodes where you want to load data:

  • node - On the local node.

  • rack - On the local rack.

  • dc - In the datacenter (DC) where the local node lives.

  • all (default) - Everywhere across the cluster.

To fully restore a cluster, you should combine the scope parameter with the correct list of SStables to restore to each node. On one extreme, one node is given all SStables with the scope all; on the other extreme, all nodes are restoring only their own SStables with the scope node. In between, you can choose a subset of nodes to restore only SStables that belong to the rack or DC.
