Our platform has been running fine.
Today we added a node to the cluster to have a dedicated AJS. (May be correlated, may be unrelevent).
However, the Data\PlatformSearchData\workplace\DeltaIndexes directory is abnormally filling with several large files.
The index has been built and has been updating on schedule correctly.
We did not initiate a rebuild of the index.
Why today is the delta index filling so much with temporary data?
