30min talk at the #CassandraSummit London 2014 with @BriceDutheil and @DoanDuyHai
At Libon, we process a lot of data. A lot means billions of messages/calls and billions of backed up contacts data. All the messaging backup is done in Cassandra with read & write latency below 10ms. Since we are happy with the level of performance achieved with Cassandra, we decided to migrate the contacts backup as well into Cassandra. During this session, we'll see how to tackle a migration project, from the SQL and Hibernate couple to Cassandra and Achilles. We'll highlight some mistakes to avoid and some tricks to make the migration smoother and more resilient.
