Making Query to Remote MongoDB Faster

[Rifat Mahmud]

I am running embedded drill on a single 8 core, 16 GB RAM machine. I am
performing a join query(select * from t1, t2 where t1.a = t2.b) on a remote
MongoDB database. The tables(collections) contain 2 and 4 rows(documents)
only. The query is taking 27 seconds.
Can the query be made faster by using drill with Zookeeper cluster? And if
the answer is yes, by how many factors? Please, elaborate about the
real-timeliness of Apache Drill.
