> When testing the branch-2's write performance in our internal cluster, we
> found that the region will be inexplicably split.
> We use the default ConstantSizeRegionSplitPolicy and
> hbase.hregion.max.filesize=40G，but the region will be split even if its
> bytes size is less than 40G(only ~6G).
> Checked the code, I found that the following path will accumulate the
> store's storeSize to a very big value, because the path has no reset..
> {code}
> RsRpcServices#getRegionInfo
> -> HRegion#isMergeable
> -> HRegion#hasReferences
> -> HStore#hasReferences
> -> HStore#openStoreFiles
> {code}
> BTW, we seems forget to maintain the read replica's storeSize when refresh
> the store files.
