Hi All, I would like to read the data from RDBMS to spark (2.0) using sparksession. How can i decide upper boundary, lower boundary and partitions. is there any specific approach available.
How Sqoop2 decides number of partitions, upper and lower boundary if we are not specifying anything. -- Selvam Raman "லஞ்சம் தவிர்த்து நெஞ்சம் நிமிர்த்து"
