Julien Le Dem commented on PARQUET-216:
---------------------------------------
We should do some measurement on our existing datasets. (CC [~alexlevenson])
Converting one file of each should be enough.
Things to look at:
- file size
- read speed
- write speed
> Decrease the default page size to 64k

> Impala uses 64k for a page size and recommends smaller page sizes over the
> current 1MB default. We're considering an absolute minimum row group size of
> 1MB, so it makes sense to dial the page size down a bit.
