This document summarizes a presentation comparing Couchbase, MongoDB, and Cassandra. It outlines some pros and cons of each: Couchbase handles objects better in memory and is safer during power failures, MongoDB is easy to use but hard to move data, and Cassandra is optimized for write speed but more complex for developers. It also notes that Couchbase and MongoDB are more suited for user applications while Cassandra is better for big data analysis.

- 3. Cassandra • Pros - Optimized to write very rapidly (+ cache) - Real-time vs Analytics: More suitable for analytics - Can add many nodes but re-write in-memory and database file • Cons - Complex design for app developers - Read vs Write – Cassandra’s Read: Always complex - Column collection - Schemable Copyright © 2012 DOCOMO Innovations, Inc. All Rights Reserved. 3
- 4. MongoDB • Pros - Really competing (rather than Cassandra, for Couch) - Easy to use - Ad-hoc Query approach for beginner developers • Cons - Hard to do data moving (to another database) by sharding - Couch thinks Ad-hoc Query capability is more important - Couch is trying to fill the gap in MongoDB Copyright © 2012 DOCOMO Innovations, Inc.

- 5. Couchbase vs. MongoDB • Object Handling in Memory - Mongo: Mongo has OS memory-mapped tech but In-memory only → page fault - Couch: In-memory + database file Re-cache - scheduled • Power Failure - Mongo: While flushing memory to disk - Couch: Transaction completing → Commit, crash-only architecture – safer Copyright © 2012 DOCOMO Innovations, Inc.

- 6. Couchbase, Mongo and Cassandra • Performance - Mongo: Object write data into memory, MRU mechanism - Couch: Caching gracefully: Memory mapping object / Memory managed object tech - Cassandra: Write throughput is faster • Big Data Analysis vs Big User Data - 1) How do we analyze big data? (Cassandra) - 2) How do we build application? (Couch) • Geo - Mongo: Mongo w/ API is better than Geocouch Copyright © 2012 DOCOMO Innovations, Inc. All Rights Reserved. 6
