Title:

Beyond Bigtable: Challenges in Cassandra 2.0

System:

Cassandra

---

Talk Info:

Cassandra has fulfilled its original design as a Bigtable/Dynamo hybrid and is moving beyond it with the release of 2.0 last month. (I have annotated the original Cassandra LADIS paper with comparisons to modern Apache Cassandra at [1].)

I will talk about integrating Paxos with an eventually consistent system, using cardinality estimation to improve compaction efficiency, and improving request isolation while preserving operation commutativity. I will also discuss some challenges on Cassandra’s roadmap such as tombstone collection and support for petabyte-scale clusters.
