> Basically I'm trying to create largish 2-4GB shards using
> LogByteSizeMergePolicy, however I've found in the attached unit
> test segments that exceed maxMergeMB.
> The goal is for segments to be merged up to 2GB, then all
> merging to that segment stops, and then another 2GB segment is
> created. This helps when replicating in Solr where if a single
> optimized 60GB segment is created, the machine stops working due
> to IO and CPU starvation.
