MongoDB and Apache Cassandra are both popular NoSQL distributed database systems. In this article, I will review how the CAP and PACELC theorems classify these systems. I will then show how both systems can be configured to deviate from their classifications in production environments. The CAP Theorem The CAP theorem states that a distributed system […]

Using PrivateLink, it is impossible by design to contact specific IPs within a VPC in the same way you can with VPC peering. VPC peering allows a connection between two VPCs, while PrivateLink publishes an endpoint that others can connect to from their own VPC.

There comes a time when your Apache Cassandra implementation will require scaling down or general maintenance (significant drop in disk usage or a number of reads and writes per second, etc.). Removing a node, whether it is working or not, falls under this scaling and maintenance. When scaling down, it is necessary to have the […]

Having explored one fork in the path (Elasticsearch and Kibana) in the previous pipeline blog series, in this blog we backtrack to the junction to explore the alternative path (PostgreSQL and Apache Superset). But we’ve lost our map (aka the JSON Schema)—so let’s hope we don’t get lost or attacked by mutant radioactive monsters.

In my previous PostgreSQL blog, we discovered what data types are available in PostgreSQL (a lot) and hopefully determined the definitive mapping from PostgreSQL to SQL/JDBC to Java data types. However, even armed with this information you have to be careful about type conversion/casting, and watch out for run-time errors, truncation, or loss of information.

How do you use PostgreSQL from Java? With JDBC! (Java Database Connectivity). There’s a PostgreSQL JDBC Driver (PgJDBC for short) which allows Java programs to connect using standard, database independent, Java code. It’s an open source Pure Java (Type 4, which talks native PostgreSQL protocol) driver and is well documented.
