Hi Ramasamy,
Let's define some terms. By "parallel requests" do you mean multiple people
submitting queries at the same time? If so, then Drill handles this just fine:
Drill is designed to run multiple queries from multiple users concurrently.
There is a caveat. Many people run Drill in embedded mode when they get
started. Embedded mode is a single user, single-machine setup that is great for
testing Drill, exploring small data sets and so on. However, to support
multiple concurrent queries, the proper way to run Drill is as a service,
preferably across multiple machines. Further, if you are running a cluster of
two or more machines, you need some kind of distributed file system: S3,
Hadoop, etc.
Once you start running concurrent queries, memory becomes an important
consideration, especially if your JSON files are large and you are doing
memory-intensive operations such as sorting and joins. The Drill documentation
explains the correct configuration steps.
Thanks,
- Paul

Hi, I did an analytics web application on drill, data set in json file. We
are facing issues while getting multiple parallel requests. Does Apache
Drill support concurrent requests?. Please let me know
