-------------------------------------------------------
[~pvillard] [~bende], to be honest I did not look at ConvertRecord as a
possible place for ParquetWriter. I found ConvertAvroToParquet like operator
would make sense, which is highly inspired from ConvertAvroToOrc.
Its true that PositionOutputStream (way to write to OutputStream) is a fairly
recent feature added by parquet. I found a similar implementation in [Apache
Beam|https://github.com/apache/beam/blob/master/sdks/java/io/parquet/src/main/java/org/apache/beam/sdk/io/parquet/ParquetIO.java]
project as well.
I have been using ConvertAvroToParquet in my deployment for over a month. I
found this to be quite handy and straightforward, so thought of contributing.
Let me know if you think this processor should best be part of ConvertRecord. I
will start exploring it.

> Processor ConvertAvroToParquet
> -------------------------------
>
> Key: NIFI-5706
> URL: https://issues.apache.org/jira/browse/NIFI-5706
> Project: Apache NiFi
> Issue Type: New Feature
> Components: Extensions
> Affects Versions: 1.7.1
> Reporter: Mohit
> Priority: Major
> Labels: pull-request-available
>
> *Why*?
> PutParquet support is limited to HDFS.
> PutParquet bypasses the _flowfile_ implementation and writes the file
> directly to sink.
> We need a processor for parquet that works like _ConvertAvroToOrc_.
> *What*?
> _ConvertAvroToParquet_ will convert the incoming avro flowfile to a parquet
> flowfile. Unlike PutParquet, which writes to the hdfs file system, processor
> ConvertAvroToParquet would write into the flowfile, which can be pipelined to
> put into other sinks, like _local_, _S3, Azure data lake_ etc.
