Subject Largest 'sensible' value
Date Mon, 02 Apr 2012 09:23:16 GMT
Hi,

We are in the early stages of thinking about a project that needs to store
data that will be accessed by Hadoop. One of the concerns we have is around
the Latency of HDFS as our use case is is not for reading all the data and
hence we will need custom RecordReaders etc.

I've seen a couple of comments that you shouldn't put large chunks in to a
value - however 'large' is not well defined for the range of people using
these solutions ;-)

Doe anyone have a rough rule of thumb for how big a single value can be
before we are outside sanity?

thanks
