Transactions Example

In this example a Pivotal GemFire / Apache Geode client will be configured to perform the basic CRUD operations within a transaction. First, it will do a successful transaction where entries are saved to the server, and then a failed transaction where all changes are reverted.

To run the example simply run the tests located under transactions/src/test in your IDE.

The client is configured to connect to the server on localhost port 40404. There is no need to start the server separately, as that is taken care of by the test.

Running the example

The example is broken up into multiple steps:

1. Print number of entries on server
2. Insert (Put) five Customer entries into the Customers region using the repositories save method.
3. Printing out the size of the region on the server
4. Update the Customer for id=2 in a transaction. Recording the before and after Customer detail.
5. Fail a transaction to update the Customer with id=2. Recording the before and after Customer detail.
6. Update the Customer for id=2 with a delay of 1000 ms.
7. Update the Customer for id=2 with a delay of 10 ms.
8. Print customer for id=2

NOTE: Inorder to see output, you must change the loglevel from "error" to "info" in the logback.xml file located under src/test/resources.
