    Description

      We currently don't bound or manage the data array size used by column vectors in the vectorized reader (they're just bound by INT.MAX) which may lead to OOMs while reading data. In the short term, we can probably intercept this exception and suggest the user to disable the vectorized parquet reader.
      Longer term, we should probably do explicit memory management for this.
