    • Method Detail

      • setRetention

        public AlterArgs setRetention​(Duration retention)
        Set the maximum age for samples compared to the highest reported timestamp, in milliseconds. Samples are expired based solely on the difference between their timestamp and the timestamps passed to subsequent TS.ADD, TS.MADD, TS.INCRBY, and TS.DECRBY calls.

        When set to 0, samples never expire. When not specified, the option is set to the global RETENTION_POLICY configuration of the database, which by default is 0.

        Parameters:
        retention - the retention, must not be null
        Returns:
        the current AlterArgs
      • forever

        public AlterArgs forever()
        Set the retention duration so the samples never expire.
        Returns:
        the current AlterArgs

      • chunkSize

        public AlterArgs chunkSize​(int size)
        Sets the initial allocation size, in bytes, for the data part of each new chunk. Actual chunks may consume more memory. Changing chunkSize (using TS.ALTER) does not affect existing chunks.

        Must be a multiple of 8 in the range [48 .. 1048576]. When not specified, it is set to 4096 bytes (a single memory page).

        Parameters:
        size - the chunk size, between 48 and 1048576
        Returns:
        the current AlterArgs
      • duplicatePolicy

        public AlterArgs duplicatePolicy​(DuplicatePolicy policy)
        Set the policy for handling insertion (TS.ADD and TS.MADD) of multiple samples with identical timestamps.

        When not specified: set to the global DUPLICATE_POLICY configuration of the database (which, by default, is BLOCK).

        Parameters:
        policy - the policy, must not be null
        Returns:
        the current AlterArgs
      • label

        public AlterArgs label​(String label,
                               Object value)
        Set a label-value pairs that represent metadata labels of the key and serve as a secondary index.

        The TS.MGET, TS.MRANGE, and TS.MREVRANGE commands operate on multiple time series based on their labels. The TS.QUERYINDEX command returns all time series keys matching a given filter based on their labels.

        Parameters:
        label - the label, must not be null
        value - the value, must not be null
        Returns:
        the current AlterArgs
