How to wait for a new index to be ready

[tzarger]

We are creating an index then later adding some more fields, and when patching the data right after programmatically updating the index, the side-by-side index is created and then eventually when the side-by-side index is done, then replaces the original index.

Since we need to immediately run a patch, the field we are patching does not exists yet since the side-by-side index is not done.

How can we know then the side-by-side index is done and the new fields added are there? Or how can we wait for that?

Hope this makes sense.

Thanks!

You can get the indexing status. The easiest way is to check the if a side by side index exists and poll it every few minutes.
There is the GetIndexesStatisticsOperation you can use for that.
Check if there is a result for side by side and if the main one IsStale is.
