This change results in unintuitive behaviour for parquet compression codec:
This is flink-write-conf:
`FlinkWriteConf`
```
public String parquetCompressionCodec() {
return confParser
.stringConf()
.option(FlinkWriteOptions.COMPRESSION_CODEC.key())
.flinkConfig(FlinkWriteOptions.COMPRESSION_CODEC)
.tableProperty(TableProperties.PARQUET_COMPRESSION)
.defaultValue(TableProperties.PARQUET_COMPRESSION_DEFAULT)
.parse();
}
```
It defaults to `TableProperties.PARQUET_COMPRESSION_DEFAULT` if (which is
gzip)
Now, in my **table** properties, I have set
`write.parquet-compression-codec` to `zstd` _explicitly_.
In this change, my explicit setting of `write.parquet-compression-codec` is
overriden by a default in flink, which seems like bad behaviour. Is this
intended?
