It is a map under the spec key with a single key: The index type of begin_search indicates that input keys appear at a constant index.

unknown: an unknown type of specification - see the incomplete flag section for more details.

keyword: key names start after a specific keyword (token).

index: key name arguments begin at a constant index.

The begin_search value of a specification informs the client of the extraction's beginning.

flags: indicate the type of data access.

notes: notes about this key spec, if there are any.

find_keys: the rule for identifying the keys relative to the BS.

begin_search:: the starting index for keys' extraction.

Key specifications are maps with the following keys: That said, most cluster-aware clients only require a single key name to perform correct command routing, so it is possible that although a command features one unfamiliar specification, its other specification may still be usable by the client. However, a Redis client that implements key specifications support can consolidate most of its keys' extraction logic.Įven if the client encounters an unfamiliar type of key specification, it can always revert to the COMMAND GETKEYS command.

It can continue using the legacy first key, last key and step scheme along with the movablekeys flag that remain unchanged. Key specifications provide a robust and flexible mechanism, compared to the first key, last key and step scheme employed until Redis 7.0.īefore introducing these specifications, Redis clients had no trivial programmatic means to extract key names for all commands.Ĭluster-aware Redis clients had to have the keys' extraction logic hard-coded in the cases of commands such as EVAL and ZUNIONSTORE that rely on a numkeys argument or SORT and its many clauses.Īlternatively, the COMMAND GETKEYS can be used to achieve a similar extraction effect but at a higher latency.Ī Redis client isn't obligated to support key specifications. The 9th element in the reply of COMMAND (and COMMAND INFO) is an array that consists of the command's key specifications.Ī key specification describes a rule for extracting the names of one or more keys from the arguments of a given command. Many of the commands in Redis accept key names as input arguments.
