new ORC notes - animeshtrivedi/notes GitHub Wiki

In the file OrcColumnarBatchReader has in initialize function, this line

recordReader = reader.rows(options);

which I also have in my file format benchmark (so this is cool, I wasn't off).

In initBatch function, the ORC schema (i also had this (IAHT)), it does batch = orcSchema.createRowBatch(CAPACITY);

What is this copyToSpark is about // Just wrap the ORC column vector instead of copying it to Spark column vector. - this we can do as well. Why would you do otherwise?
