Difficult time has come to my free time that I can spend to write blog posts. It’s high time to update how OLR project is doing. Well, the project is doing fine and had major improvements. This briefly explains new features of the project.
Every version apart from bug fixes and stability improvements include new major features:
Version 1.8.0
This is a performance and stability release. Most focus has been spent on performance. The speed of redo log processing might increase up to 20 % in some cases.
The major feature of this release is ability to add key parameters to Kafka messages allowing better further processing within Kafka.
This ver sion can also process DDL commands with any size. Previously it had 4k limitation inf SQL size.
Version 1.7.0
This version introduces the ability to of process transaction in any size. This is possible thanks to ability to swap to disk when the amount of available memory is too low.
Another major improvement is better control over timezone what allows precisely operating when database server and server hosting OLR operate in different timezone.
Version 1.6.0
This release introduces many technical features which increase ease of use of OLR.
