[@shubhamwaingade4144]

Doubts:
1. Does the read take place on the machine where spark is installed or the machine where the data base is hosted?
2. What will be upper and lower bounds in terms of partition column is of timestamp data type?
3. If 5 executors are running in parallel will there be 5 connections fired to the database?

[@vedantshirodkar]

Sir, I have one question.
If spark has to write a data to sql database and as our data is broken on to multiple worker nodes, so is it driver who establishes single connection with sql db or it is worker nodes who establishes multiple parallel connections ?

[@koppisettysatish]
