Agreed that there is not much to go on here in the original question. I will say that we very recently found a good fit with Solr and Cassandra in how we deal with a very heavy write volume of news article data. Cassandra is excellent with write throughput and high availability, but our search use cases are with time-dependent news content, so we need lots of term proximity, faceting and ordering functionality.
We probably could store everything in Solr, but the above approach will allow us to make articles immediately available in a fault-tolerant manner while being able to efficiently send batches at regular intervals to Solr and therefore scale out our ingestion of news articles a little smoother. Full disclosure: I am still getting my head around the innards of Solr replication and clustering, but so far I feel like we made a good choice. Hopefully the above will be helpful to folks during their evaluations. Cheers, -Nate On Thu, Jan 7, 2010 at 10:02 AM, Joseph Bowman <bowman.jos...@gmail.com> wrote: > I have to agree with Tatu.
