I use solr and cassandra but not together. I write what I want indexed into solr (and only unstructured data), and related data into either cassandra or oracle. I use the same key across all three db's.
When I need full text search etc, I read the data from solr, grab the keys, and go get the data from the other db's. This avoids conflation of concerns, isolates failures, but is dependent upon multiple writes. I use a message bus and services based approach. In my experience, at scale this approach works better and avoids vendor lock in. -- Colin Clark +1 612 859 6129 Skype colin.p.clark > On Feb 2, 2015, at 7:25 AM, Asit KAUSHIK <asitkaushikno...@gmail.com> wrote: > > I tried elasticsearch but pulling up the data from Cassandra is a big pain. > The river pulls up all the the data everytime and no incremental approach. > Its a great product but i had to change my writing approach which i am just > doing in Cassandra from .net client . > Also you have to create a separate infrastructure for elasticsearch. > Agin this is what i found with limited analysis on elasticsearch > > Regards > Asit > > >> On Mon, Feb 2, 2015 at 11:43 AM, Asit KAUSHIK <asitkaushikno...@gmail.com> >> wrote: >> Also there is a project as Stargate-Core which gives the utility of querying >> with wildcard characters. >> the location is >> https://github.com/tuplejump/stargate-core/releases/tag/0.9.9 >> >> it supports the 2.0.11 version of cassandra.. >> >> >> >> Also elasticsearch is another product but pumping the data from Cassandra is >> a bad option in elasticsearch.
