Overview
What we did
- Tested the feasibility of replacing Oracle for a specific time-series use case: aggregating billing events to generate invoices at a given cadence (30 to 60 days); to perform the test, Pythian delivered a time-series Cassandra PoC hosted on Google Cloud virtual machine instances
- Selected Terraform to provision the virtual machines, and Puppet automated the installation of Apache Cassandra
- Exported client’s billing events from their Oracle database as a CSV file, which was ingested via Apache Spark
Technologies used
Key Outcomes
The volume and complexity of today’s data calls for open-source, non-relational databases that operate in the cloud. Thanks to Pythian and their expertise in data and cloud, we now have a clear strategy for using that technology.
