Subject Writes and Loggers
Date Wed, 10 Oct 2012 19:47:30 GMT
Hi all,
I want to verify some of the details with Accumulo Writes and Loggers. 

How does the client find the correct tablet server to write to?  Does the client query the
master once and receive the ranges associated with each tablet server? Is this list in zookeeper?

With write-ahead loggers, when a client makes a write request, to a tablet server:
	The tablet server writes the data to a write-ahead logger which is stored on a different
	Then acknowledges the client 
	Then writes adds data to its in memory table.

Do I have this order correct?

Is the number of loggers always fixed, can this be changed with server properties?

Thanks in advance,
