Subject Question about how queries are distributed
Date Sun, 03 Aug 2008 23:22:10 GMT

I'm looking for some information on hbase's architecture (out of pure
interest), which i wasn't able to find anything about it on the Hbase site
(including the architecture description).

Specifically, I am curious how writes/mutations are distributed amongst the
servers, and whether this is different when using an interface like Thrift.
Is a server located for each mutateRow () operations "asked for" at the
master server, or is that cached at some level ? If not, how is that problem
solved that a client only connects to the master server but actually needs
to talk to one of the slave servers ? Or is the master server a single weak
spot that could introduce scalability problems on large (huge) scale ?

Thanks in advance for any responses!
