Please, review it and merge. This is very important feature. For example, adding date= as a prefix will allow us to declare all folders of rudderstack outputs as a Hive partitioned table

@gitcommitshow, done

@gitcommitshow how we move forward with this? We should wait for review from RS or something else? If we wait for review could you provide approximate deadlines for that?

@maratbakiev2 internal disucssion has been started already. Can't say about the deadline to merge but I'll try to close the discussion before next weekend.

One thing the team pointed out was that the partitioning is already supported for datalake destinations. I don't have complete knowledge about that, let me gather some more info to move the discussion ahead.

@gitcommitshow

partitioning in terms of writing to separate folders for each day is indeed supported. But! One of the most popular technologies to process that data is Hive and Hive (Hive Metastore) needs partitions in the format of column=value, for example date=2023-06-08. While currently rudderstack uses just values (2023-06-08) as folder names
