@NotThreadSafe
public class HoodieAvroParquetWriter<R extends org.apache.avro.generic.IndexedRecord>
extends HoodieBaseParquetWriter<org.apache.avro.generic.IndexedRecord>
implements HoodieFileWriter<R>

HoodieParquetWriter extends the ParquetWriter to help limit the size of underlying file. Provides a way to check if the current file can take more records with the canWrite() ATTENTION: HoodieParquetWriter is not thread safe and developer should take care of the order of write and close
