Hi Dulitha,

The doc you are referring to is for DAS 3.0.0 NOT DAS 3.0.1.
Refer to [1] for DAS 3.0.1 docs.

In DAS 3.0.0, ANALYTICS_FS_DB is used to store the index data.

But from 3.0.1 onwards, we are storing those data in the local filesystem,
not in a database.
That's why we have removed the FS_DB from the latest release.
So you don't have to configure the ANALYTICS_FS_DB in DAS 3.0.1.

Regards,
Sachith
