Hi,We have data which is few level nested. If we want to read only one column
from some lower level structure, does Parquet read the complete higher level
structure? Or it only reads that column and assemble the structure and return.
For example, my conceptual schema is as follows struct Level1 { struct
Level21{ x : int; struct level3 {
............... } } struct Level22{
..... } }
Now if I need to read only Level.Level21.x, what will parquet do? read
everything under Level1 or Level2 or only Level1.level2.x?
If yes, are there any pointers( like example, test class, JIRA or doc) around?
Thanks,Mohammad
