We are having trouble with flushing our translog now that we are on version 6.x. We are using default settings, other than our index has refresh_interval set to 60s.
Indices often have huge translogs (1GB) at the end of the hour. It seems the default translog settings in 6.3 would cause a flush to occur automatically.
In previous versions, we'd do a _flush after the indexing was complete for an index, to ensure the translog was processed and removed. The _flush API does not appear to work now.
Any help would be appreciated.
