Vectorized iceberg reader
anjalinorwood opened a new pull request #375: Vectorized iceberg reader
URL: https://github.com/apache/incubator-iceberg/pull/375
This commit:
+ implements batched version of iterators (BatchedPageReader,
ColumnarBatchReader etc) as the value-based iterator abstractions
were taking up too much CPU.
+ moves the reads close to page level by consulting the definition
levels and directly reading from values vector.
