Nodetool upgradesstables¶

upgradesstables - Upgrades each table that is not running the latest Scylla version, by rewriting the SSTables.

Note that this is not required when enabling mc format, or upgrading to a newer Scylla version. In these cases, Scylla writes a new SSTable, either in MemTable flush or compaction, while keeping the old tables in the old format.

You can specify to run this action on a specific table or keyspace or on all SSTables. Use this command when changing compression options, or encrypting / decrypting a table for encryption at rest and you want to rewrite SSTable to the new format, instead of waiting for compaction to do it for you at a later time.

Syntax: nodetool <options> upgradesstables [upgrade target]

Where:

<options> are the Nodetool Generic Options

[upgrade target] indicates what you are upgrading and can be any of the following:

• --include-all-sstables | -a - Upgrades all SSTables by force, including those already in the new SSTable format.

• --jobs <jobs> | -j <jobs> - Indicates the number of SSTables you want to upgrade simultaneously. Setting this parameter to 0 uses all available compaction threads.

• keyspace-name - Updates all SSTables for all tables in the indicated keyspace

• table-name - Updates all SSTables for the indicated table or tables, with each table separated by a space. To specify a table, you must include the keyspace-name and the table-name separated by a space.

• -- Separator which can be used to seperate an option from an argument. For example, if you are using the -a flag, use the separator between the flag and the keyspace-name
