LuciaCache - What is this?

[BobbyTables]

What is LuciaCache in the context of PowerBI Desktop? And can I delete the contents in that folder? It is not the normal cache which can be cleared from within PowerBI Desktop.

@BobbyTables,

Based on my test, it has no impact on existing PBIX file or Power BI Desktop when I delete the LuciaCache folder from my computer. Regarding to that what is the LuciaCache used for, I will consult internally and post back once I get any information.

@Anonymous: Thanks for the test! My LuciaCache folder tends to be quite big, hence the question. Looking forward to hear what the LuciaCache is (mainly pure curiosity 🙂 ).

@BobbyTables,

I got response from PG:

"This is for caching the index for fast look up of terms that is used for Q&A experience. If the customer is not interested in Q&A. They can opt out and we don’t create the index on the disk. "

Hi, is it safe to say that we can delete BOTH LuciaIndex and LuciaCache? Thanks.
