During these two years, our early adopters migrated from a variety of database solutions, and while most of the migrations we successfully completed were Apache Cassandra (enterprise and open-source versions), we have seen users migrate from MongoDB, HBase, relational systems such as MySQL and Postgres, and key/value stores like Memcache and Redis. Migration strategies differ between users and systems. In general, we can divide Apache Cassandra-to-Scylla migrations into two main strategies, cold migration and hot migration. Cold Migration […]

Faster and better: What to expect running Scylla on AWS i3 instances

AWS i3 monitoring

Amazon recently unveiled a new class of machines—the AWS i3 family.
