Related with #3298.

  • Add an extension which provides two aggregator timeMax and timeMin.
  • Internally, it stores timestamp value as Long so that we can have DateTime with group by query by finalizeComputing() but only get Long value with select query.
  • To support parsing of string represented timestamp, TimestampSpec is slightly modified.
  • Incremental index is also modified to accept many different type of timestamp at ingestion time.

@sirpkt does this conflict with #3168?

Can we get some docs on what timeMax and timeMin do? I'm not entirely clear from reading the description

@fjy This is different from #3168.
Its resolution is the same as query granularity because __time is, while this patch returns exact min/max value.
#3168 returns one min/max time for the entire group of (maybe filtered) data while this patch returns separate min/max time for each row of aggregated data.

I think this still needs docs, looks good to me aside from that
