Jacques Nadeau commented on DRILL-19:
-------------------------------------
Timothy is working at
https://github.com/tnachen/incubator-drill/tree/executor-java
Few thoughts/questions as I go through this.
-You should update intellij to use a template that doesn't have any header
information other than the Apache license. Then you won't have to go back
through and fix things.
-Do you have an easy way to output the found schema so we can see it?
-Talk to me a little about your concept of RecordBatch. It seems like
individual operators should be unaware of batches.
My thoughts were along the lines of
class PhysicalOperatorIterator{
enum NextOutcome {NONE_LEFT, INCREMENTED_SCHEMA_UNCHANGED,
INCREMENTED_SCHEMA_CHANGED}
public Record getRecordPointer(); // called once
public RESPONSE_TYPE getNext(); // changes the meaning of the pointer
}
class Record{
public Value getValue(int fieldIndex);
> Build a JSON scanner that does schema discovery
