> We can only load 100k blocks from a file. If 256Gs of SSD and blocks are 4k in size to align with SSD block read, and you want it all in cache, the 100k  limit gets in the way (The 100k may be absolute limit... checking. In UI I see 100k only). There is a configuration which lets you up the number per file, hbase.ui.blockcache.by.file.max. This helps.
