Introduction to v2.9.5

We have completed 9 issues in the new version, which contains 3 features.

Version 2.9.5 focuses on horizontal scalability.

So far, LiteFlow natively supports all relational databases, 3 popular registration centers, and 1 configuration center on the storage plug-in. There are 5 plugins in total, which should cover the choices of most people.

In version 2.9.5, LiteFlow added 2 new languages, python and lua, in terms of script support. So far, up to 5 scripting languages ​​have been supported.

Why use Java when writing java projects?

LiteFlow allows you to create a Java project, and all business codes can be scripts. Everything is hot refreshable.

Support Apollo

We would like to thank the contributors of the community Hello team for providing Apollo support plug-ins for LiteFlow.

LiteFlow will support more and more other third-party middleware in the future.

For details on how to use the Apollo plug-in, see the Apollo configuration source chapter on the official website.

Provides support for Python and Lua scripting languages

I thought it providedGroovy,Javascript,QLExpressThree scripting languages ​​are enough. I didn’t expect that some people in the community really hope to support python.

Fortunately, LiteFlow already has a very easy-to-extend mechanism in the scripting base layer. This time, we not only provide python support, but also provide lua support. I don’t know if you like lua, a scripting language. Students who have written redis scripts must be familiar with it.

Enhancement of front and rear nodes

The previous pre- and post-nodes can only be executed at the first level of the expression, which undoubtedly has certain restrictions for users.

I originally thought this would be difficult to change. Because if you want to change, you must move some underlying code. So this feature has not been optimized.

When I looked through the code this time, I found that what I originally thought might be a bit complicated, but this problem is actually not that complicated. So this time it was finally fixed.

Select the component’sDEFAULTkeywords

In the new version, we added an additional keyword to the selection componentDEFAULT, enabling an option to be executed by default if neither option matches. This is very useful in some scenarios.

For details, please refer to the Selection and Arrangement section of the official website.
