Subject Re: Is Cassandra suitable for this use case?
Date Thu, 25 Aug 2011 16:32:45 GMT
hi Evgeny

I appreciate the input.  The concern with HDFS is that it has own
share of problems - its name node, which essentially a metadata
server, load all files information into memory (roughly 300 MB per
million files) and its failure handling is far less attractive ... on
top of configuring and maintaining two separate components and two API
for handling data. I am still holding out hopes that there might be
some better way of go about it?

Best Regards,
