>>Any update on your production indexing parameters? Did you end up sticking with ramBufferSizeMB=320, mergeFactor=28, termIndexInterval=1024?
We are now using a similar scheme where we vary the settings for each shard, but we are using the new TieredMergePolicy with settings for maxMergeAtOnce from 29-40 and segmentsPerTier from 39-40, and a maxMergedSegmentMB of 20,000 (20GB). We also vary the ramBufferSizeMB from 320-1526.
