     1  # The following collectors are available:
     2  # - value-first - uses the first character of the value to construct an interval
     3  # - value-last - uses the last character of the value to construct an interval
     4  # - suffix - constructs an interval from the '@timestamp' suffix of each key
     5  # - suffix-point-keys-only - same as "suffix", but only applies to point keys
     6  # - suffix-range-keys-only - same as "suffix", but only applies to range keys
     7  # - nil-points-and-ranges - a trivial collector with neither a point nor range collector
     8  
     9  # Single collector.
