Error:

I have a workflow using a generic reader and it give me below warning:

2022-03-10 22:07:41| 135.3| 0.3|WARN |Detected 2600000 unique Attribute Names strings in the translation. Several unique names may result from operations like list attribute creation or feature type fanout. Reducing the number of unique names may improve translation performance and reduce memory usage

any idea what the reason is?

Never had this one. It looks like workbench is detecting a very high number of individual attributes which can negatively influence performance.

What data type are you reading?

@davekazemi​ is your reader creating many FME list{} attributes? That is often a cause for this WARN message.

Would be great to have a bit more detail with the message. For example what field and what transformer to look at. I'm also getting it and have no idea what to do. The only way to narrow it down is to deactivate parts of the workspace and see when it disappears and when it comes back.
