  • PERSIST

    redis and generic | Mar 9, 2016

    Remove the existing timeout on key, turning the key from volatile (a key with an expire set) to persistent (a key that will never expire as no timeout is associated).

  • OBJECT

    redis and generic | Mar 9, 2016

    The OBJECT command allows to inspect the internals of Redis Objects associated with keys. It is useful for debugging or to understand if your keys are using the specially encoded data types to save space. Your application may also use the information reported by the OBJECT command to implement application level key eviction policies when using Redis as a Cache.

  • MOVE

    redis and generic | Mar 9, 2016

    Move key from the currently selected database (see SELECT) to the specified destination database. When key already exists in the destination database, or it does not exist in the source database, it does nothing. It is possible to use MOVE as a locking primitive because of this.

    redis and generic | Mar 9, 2016

    Atomically transfer a key from a source Redis instance to a destination Redis instance. On success the key is deleted from the original instance and is guaranteed to exist in the target instance.
