digitalis.io is a UK based Apache Cassandra and DataStax Enterprise specialists. The founders have been heavily involved with Apache Cassandra since 2010, soon after it was open sourced by Facebook. We have been helping to design and implement highly successful Cassandra projects as well as rescue large number of Cassandra and DataStax Enterprise clusters from small to VERY large.
We also have the battle scars from dealing with production cluster failures through bugs, bad configs, terrible data modelling, bad architecture, wrong hardware, you name it, we have seen them all!
digitalis.io provides consulting as well as managed services for both Apache Cassandra and DataStax Enterprise.
