Review Comment:
I also tried
```
try (FileAppender<GenericData.Record> writer =
Parquet.write(Files.localOutput(parquetFile))
.schema(schema)
.createWriterFunc(ParquetAvroWriter::buildWriter)
.set(PARQUET_DICT_SIZE_BYTES, "2048")
.set(PARQUET_PAGE_ROW_LIMIT, "100")
.build()) {
writer.addAll(records);
}
```
and debugged what happens in `writer`.
The following chain is called to get the `ValuesWriter` for the decimal
column:
https://github.com/apache/parquet-java/blob/apache-parquet-1.13.1/parquet-column/src/main/java/org/apache/parquet/column/impl/ColumnWriterBase.java#L84
https://github.com/apache/parquet-java/blob/apache-parquet-1.13.1/parquet-column/src/main/java/org/apache/parquet/column/ParquetProperties.java#L167
https://github.com/apache/parquet-java/blob/apache-parquet-1.13.1/parquet-column/src/main/java/org/apache/parquet/column/values/factory/DefaultValuesWriterFactory.java#L52
https://github.com/apache/parquet-java/blob/apache-parquet-1.13.1/parquet-column/src/main/java/org/apache/parquet/column/values/factory/DefaultV1ValuesWriterFactory.java#L55
https://github.com/apache/parquet-java/blob/apache-parquet-1.13.1/parquet-column/src/main/java/org/apache/parquet/column/values/factory/DefaultV1ValuesWriterFactory.java#L80
which is the code I cited previously:
```
private ValuesWriter getFixedLenByteArrayValuesWriter(ColumnDescriptor
path) {
// dictionary encoding was not enabled in PARQUET 1.0
return new FixedLenByteArrayPlainValuesWriter(path.getTypeLength(),
parquetProperties.getInitialSlabSize(),
parquetProperties.getPageSizeThreshold(), parquetProperties.getAllocator());
}
```
I am using the `iceberg-parquet` APIs to create a writer, but eventually it
calls `parquet-java` code.
