Subject [jira] [Commented] (ACCUMULO-4806) Allow offline bulk imports
Date Fri, 09 Feb 2018 15:48:00 GMT

Ed Coleman commented on ACCUMULO-4806:
--------------------------------------

It would go al long way if the splits could be added at table creation or when table is offline. 
When the other API changes were made by Mark, I wondered if this task could also could be
done at that time - but I believe that it was more complicated.

The delay is that when a table is created and then the splits added and then taken offline
there is a period proportional to the number of splits as they are off-loaded from the tserver
where they originally got assigned.  (The re-online with splits distributed across the cluster
is quite fast)

If the splits could be added at table creation, or while the table is offline so that the
delay for shedding the tablets could be avoided, then the need to perform the actual import
offline would not be as necessary.

> Allowing offline bulk imports would be useful for some customers. Currently these customers
already take tables offline to set split points but then have to bring them back online before
starting the import.
