> In tests, we create lots of tables and hence lots of regions. For every such region, the indexer co-processor is installed. For every such co-processor instance, we have a writer pool whose default size is 10. Although we have a keep alive policy on the thread pool, still we can have more than a 100 index writer threads active at a time doing nothing. We should just dial that number down to 1 for our tests.
