Hi All,
We have new interface methods for the ColumnReader. This methods have signature FillXXX(...).
For example:
public int fillIntValues(int[] dataBuffer, byte[] repetitionBuffer, boolean[] isNullBuffer);
These methods allow to fill the buffers with column and level data in one call, thereof saving method call per value. I think that we should migrate to these methods, since it is not possible to get our target performance making method call per column value.
