I'm trying to figure out which database to use for storing and querying on ~1 billion JSON documents about the size of 2KB each. About 2 TB of data.

Nature of JSON documents:

  • 3 types of documents (structure is loosely defined)
  • Nested, multi level, sparse

Things that I'm looking for are:

  • High throughput
  • Secondary indexes support
  • Queries over JSON

Nice to haves:

  • SQL like query interface

Things I'm looking at:

  • Cassandra
  • Storing JSON in Postgres
  • Riak
  • HBase

If more details I missed regarding usage or the data I missed that would help make the decision, please let me know
