How to Maintain Your Cache/Database Consistency with XA Transactions

60 minutes
Recorded October 19, 2016

In this webinar

If you have a cache and a database, then failures may cause inconsistencies between the database and the cache. XA Transaction technology provides a hard line on consistency of your cache by ensuring that cache updates are rolled back along with the database transaction. The cache effectively becomes like a replicated database – albeit in-memory.

While some applications may not care too much about such consistency (and favor availability first), there is a certain niche of applications that do care about seeing consistent cache data. In our experience, these applications are mostly in the financial services and/or insurance industries.

We’ll cover these topics

  • An overview of XA transactions and consistency
  • The benefits of using Hazelcast with XA
  • Avoiding common pitfalls when configuring Hazelcast with XA
  • Live Q&A
