Ed Coleman commented on ACCUMULO-4806: -------------------------------------- I am not aware of any issues. From the client's perspective, it would actually simplify operations. Adding the splits at table creation would make the operations to prepare a table for bulk import into a new / pre-split table simpler because it could be done in one client operation rather than the current four: create table, add splits, off-line table, online table. Being able to add splits to an off-line table would require still require the same number of client operations: create table, off-line table, add splits, on-line table, just the order is different. The currently complexity is manageable, so I would defer to any approach that is easier to implement and provides equivalent performance and processing requirements. For performance I'm measuring wall total wall clock time from when the table is created to when it is ready for the bulk import to begin. For processing, I'm assuming that the processing required for adding splits at table creation or to an off-line table would be equivalent and one would not require significantly more processing power than the other - especially if the operations are performed by the master when it could impact other master operations. So, I think from a client perspective adding the spilts at creation time would be preferred. > Allow offline bulk imports > -------------------------- > > Key: ACCUMULO-4806 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4806 > Project: Accumulo > Issue Type: Sub-task > Components: master, tserver > Reporter: Mark Owens > Assignee: Michael Miller > Priority: Major > Fix For: 2.0.0 > > > Allowing offline bulk imports would be useful for some customers.
