How does BlockCache find relevant Blocks?
Hi, All,
Given a large-sized BlockCache, I am wondering how HBase performs to search
a block of a requested rowkey. Is there any index structure (in-memory)
inside BlockCache? or it search in a brute force way, (which seems unlikely
though :-...)

I am aware of reference guide online, but have not yet find the answer...
http://hbase.apache.org/book.html#block.cache

Thx,
Yun
