  • Method Details

    • setIfAbsent

      boolean setIfAbsent(byte[] key, byte[] value, long ttlMillis)
      Atomically sets a key to a value with a time-to-live only if the key does not already exist. Equivalent to Redis command: SET key value NX PX ttlMillis
      Parameters:
      key - The key to set.
      value - The value to store.
      ttlMillis - Time-to-live in milliseconds.
      Returns:
      true if the key was set, false if it already existed.

    • set

      void set(byte[] key, byte[] value, long ttlMillis)
      Updates an existing key with a new value and extends its time-to-live. Equivalent to Redis command: SET key value XX PX ttlMillis
      Parameters:
      key - The key to update.
      value - The new value to store.
      ttlMillis - Time-to-live in milliseconds.

    • get

      byte[] get(byte[] key)
      Retrieves the value associated with a key. Equivalent to Redis command: GET key
      Parameters:
      key - The key to retrieve.
      Returns:
      The value, or null if the key does not exist.

    • delete

      void delete(byte[] key)
      Deletes the specified key. Equivalent to Redis command: DEL key
      Parameters:
      key - The key to delete.
