Gang Wu updated PARQUET-2299:
-----------------------------
Fix Version/s: format-2.10.0
> Use `true` instead of `1` as default value for `is_compressed bool` field
> -------------------------------------------------------------------------
>
> Key: PARQUET-2299
> URL: https://issues.apache.org/jira/browse/PARQUET-2299
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-format
> Reporter: Matthijs Brobbel
> Priority: Minor
> Fix For: format-2.10.0

>
> I noticed that the default value for the optional boolean `is_compressed`
> field of the `DataPageHeaderV2` struct has a default value of `1`. According
> to the Thrift docs a boolean value is either `true` or `false`.
> This currently works because the Apache Thrift compiler internally handles
> bools as ints:

> It may however not work with other Thrift compilers that are more strict
> about this.
> Based on the docs and a test
> (https://github.com/apache/thrift/blob/3880a09565a9a1dad028b3679746eafac268c819/test/ThriftTest.thrift#L406)
> in the Thrift repository it seems that using `true` here is the correct way
> of defining a default for an optional bool field.
