Please could you squash the commits.
Please could you do the Chinese version as well.

[donPain]

@davidradl I made the changes, could you review it again?

[davidradl]

looks good - I notice that there is. reference in parquet.md as well to the spec for 1.10. should we align that link here as well?

[donPain]

Good point, I changed all values ​​from version "1.10.0" to "++version++".

This link seems broken

[rmetzger]

Flink is using Avro 1.11.4. Wouldn't it make more sense to link to the docs of that version, then add a note to the pom file where the avro version is defined to make sure folks update the docs when updating the avro version in the pom file?
Ref: https://github.com/apache/flink/blob/release-1.20/pom.xml#L149

Also, I believe our docs system supports variables -- it would be much easier to have one variable defining the avro version, instead of having this spread all over the place.

Apparently most of the avro documentation has broken links above 1.13.0.

Could you give me a reference on how to use variables to set the url in the documentation?

@rmetzger @donPain I had a quick look at the docs, it seems that Hugo does allow templating which supports variables. I can see the Flink code referencing the predefined variables with {{ }}. I see {{< all_versions >}} which looks like a custom variable; but I am not sure how it is populated. I see code bringing in the different connectors. I have not yet found how we would want to add global variables like this.

[davidradl]

@rmetzger as discussed at the Chi meeting are you ok to merge this? @donPain can you raise a separate issue to track the variable replacement improvement idea please.

[rmetzger]

Thanks for working on this.
Let's intro the variable in a separate JIRA / PR.

[rmetzger]

@donPain could you raise a PR forward-porting the commit to the master branch as well? Thx
