-------------------------------------

             Summary: Serve persisted region immediately after nodes restart even if indexed.
                 Key: GEODE-6361
                 URL: https://issues.apache.org/jira/browse/GEODE-6361
             Project: Geode
          Issue Type: Improvement
          Components: persistence, regions
            Reporter: Philippe CEROU
             Fix For: 1.8.0


Hi,

If we create a region with indexes and we insert million rows inside a full restart of the
product is very long, the cluster come back quickly but the region is back after minutes (Ex
: 16 minutes for a 30 nodes with 200 000 000 rows with 3 indexes) because indexes are rebuild
at restart before servicing the region.

If we create and serve a non indexed region we can stop/start quickly, if we create indexes
after creating/servicing a region with a lot of rows there is no service freeze.

Could it be possible to have a parameter that say to nodes we do not want anymore indexes
on a specific region at restart, just keep their definition, and then index back again after
region is serviced like when we create indexes ?

On our need it is not a big problem if indexes are not there at restart, it won't help but
it could be acceptable, because in our solution we need to be UP 24/24 to serve DATA acquisition/writing,
reads/selects are for few on demand consumption which can be long in case of DRP (The time
indexes are back).
