Note: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-4392

We only have low-level parquet writer at the moment, which requires user to specify values, definition levels, repetition levels, etc. This is inconvenient. Instead, we should offer high-level Parquet writer that hide these details.

[~andygrove] Yes it looks interesting to me. I'll take this if [~csun] is not available.

I think the arrow writer (that writes parquet files from arrow arrays) is a pretty good high level parquet writer
