Asynchronous RDBMS access with Spring Data R2DBC

Not too long ago, a reactive variant of the JDBC driver was released. Known as R2DBC. It allows data to be streamed asynchronously to any endpoints that have subscribed to it. Using a reactive driver like R2DBC together with Spring WebFlux allows you to write a full application that handles receiving and sending of data ...

Cached Prepared Statements with Spring Data Cassandra

Today I have a short post on using Prepared Statements in Spring Data Cassandra. Spring provides you with some utilities to make using Prepared Statements easier rather than relying on registering queries manually yourself with the Datastax Java Driver. The Spring code provides a cache to store prepared statements that are frequently used. Allowing you ...

Containerising a Spring Data Cassandra application

I'm continuing my journey of learning Docker. I am still keeping it simple at this point. This time around, I am going to tackle converting a Spring and Cassandra application to use containers instead of running locally on the host machine. More precisely, using Spring Data Cassandra to sort out the application. I wish I ...

I'm back with more Cassandra and Java integration today this time focusing on using the Datastax Java driver rather than Spring Data Cassandra which I have already written about quite a lot. The Datastax driver is actually used by Spring Data to interact with Cassandra but comes with some extra goodies built on top of ...

This was due to me not making use of Spring Boot's auto-configuration which would of allowed me to remove a whole class from my code! Therefore, in an attempt to redeem myself for not ...

Today we are going to look at reactive Spring Data Cassandra. This post is actually very similar to one that I did on Reactive Spring Data MongoDB with the only real difference being that they are obviously using different databases. For background information that will not be included in this post have a look at ...

Startup and shutdown scripts in Spring Data Cassandra

Shorter post this time round, it feels nice to get something finished faster than 2 weeks for once. Today we will look at startup and shutdown scripts in Spring Data Cassandra. This is something I probably should of done myself ages ago as it would of made testing my earlier posts much easier. I spent ...
