Solandra vs. ElasticSearch

Question

We are working with a Cassandra database that will store data in the petabyte range. We are thinking of using either ElasticSearch or Solandra, but we are having a fun time deciding between which to use. I'm wondering if the our database might get too large. I know ElasticSearch is scalable, but to what extent - especially with a Cassandra database.

Solandra on the other hand is made for Cassandra and is highly scalable, but again, to what extent?

Both are scalable, but how scalable using Cassandra?

Answer 1

Solandra is being used in the 10s of Terabytes range.

Are you saying you want to index a PB of data in solandra or a subset? I think if you want 1 big index with a PB of data you are stretching the limits. but If you want a PB of indexes, then this will scale the same as Cassandra.

How many nodes are you planning to run? how much disk per node?

Answer 2

Have a look into this nice discussion:
