If key + is also specified, check for the key with the prefix instead. + +:command:`get [out ]` + Get the value of the KV pair stored with the URL encoded prefix and key. + If file is also specified, write the value to the file. + +:command:`crc ` + Get the CRC of the KV pair stored with the URL encoded prefix and key. + +:command:`get-size [ ]` + Get estimated store size or size of value specified by prefix and key. + +:command:`set [ver |in ]` + Set the value of the KV pair stored with the URL encoded prefix and key. + The value could be *version_t* or text. + +:command:`rm ` + Remove the KV pair stored with the URL encoded prefix and key. + +:command:`rm-prefix ` + Remove all KV pairs stored with the URL encoded prefix. + +:command:`store-copy [num-keys-per-tx]` + Copy all KV pairs to another directory specified by ``path``. + [num-keys-per-tx] is the number of KV pairs copied for a transaction. + +:command:`store-crc ` + Store CRC of all KV pairs to a file specified by ``path``. + +:command:`compact` + Subcommand ``compact`` is used to compact all data of kvstore. It will open + the database, and trigger a database's compaction. After compaction, some + disk space may be released. + +:command:`compact-prefix ` + Compact all entries specified by the URL encoded prefix. + +:command:`compact-range ` + Compact some entries specified by the URL encoded prefix and range. + +Availability +============ + +**ceph-kvstore-tool** is part of Ceph, a massively scalable, open-source, distributed storage system.
