Subject Does HBase need caching layer if it served webpage
Date Fri, 15 Oct 2010 00:32:03 GMT
Google mentioned that it uses Bigtable to serve map-tiles, which basically
means it uses Bigtable to serve huge amount of data online, but it does not
mention any caching layer. But we all know HBase's random read performance
sucks (this is true for Bigtable as well, see their paper: even you increase
the number of servers for 500 times, the random read throughput just
increases 3-4 times).

I am wonder how are people handle it, any experience to share?

Also, can someone talk about what kind of caching layer can be added if
anyone practieces that?
