Enabling Partition Option in Source tab

[v-cyu]

We are utilizing Copy Activity to copy from Cosmos Structured Stream (Not CosmosDB) to a lakehouse table. 
However, in the process of copying, we are seeing this tuning tips

However, in the source tab, we do not see any "Partition Option" available.

Please let me know how we can tune this to allow parallelism and improve performance?

Hi @v-cyu 

If you are still being prompted, it is recommended that you consider checking the partition configuration of the source data to ensure that it supports and configures partitions correctly.

Hi @v-cyu

I noticed that your screenshot shows Advanced under the Source tab. Loading data into Lakehouse using partition columns is set up in Advanced under the Destination tab.
