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