Anoop Sam John commented on HBASE-23279:
----------------------------------------
The offsets index data will be written at the end of the block during
#finishBlock(). So we can not guarentee the size of the data block. All other
kind of encoding we can. Because there we track correctly what amount of
unecoded table data we are writing to block and encoded data size actually
written to disk. When any of this size reaches the block size we finish that
block. Here also we track both but this offsets accounting not coming into pic
unless the finishblock is called.
> Switch default block encoding to ROW_INDEX_V1

> Currently we set both block encoding and compression to NONE.
> ROW_INDEX_V1 has many advantages and (almost) no disadvantages (the hfiles
> are slightly larger about 3% or so). I think that would a better default than
> NONE.
