Hello, We bulk load our table and during that process, pre-split regions to optimize load across servers. The number of regions build up and we manually are merging them back. Any merge of two regions is causing a compaction which slows down our merge process.
We are merging two regions at a time and this it ends up being pretty slow. In order to make it merge more regions in a shorter window of time, should we be merging more than one? Can we do that? The reason we are doing this is that our key is sequential. In the short term, changing it is not an option. The merging helps keep the # of total regions down so that when we create 20 new regions for a load, the balancer will spread out the new regions across multiple region servers. We are currently on HBase 0.98.6 (CDH 5.3.0) Thanks, Abe
