TSREVRANGEBYTIME

Synopsis

TSREVRANGEBYTIME key low_ts high_ts [LIMIT limit]This command fetches the values for the given low_ts, high_ts range in the time series that isspecified by the given key ordered from newest to oldest. If LIMIT is specified, then at mostlimit pairs will be fetched.

  • If the given key is associated with non-timeseries data, an error is raised.
  • If the given low_ts or high_ts are not a valid signed 64 bit integers, an error is raised.
  • If limit is not a valid positive 32 bit integer, an error is raised.
  • low_ts and high_ts are inclusive unless they are prefixed with (, in that case they areexclusive.
  • Special bounds -inf and +inf are also supported to retrieve an entire range

Return value

Returns a list of timestamp, value pairs found in the range specified by low_ts, high_ts. IfLIMIT is specified, at most limit pairs will be fetched.
