--------------------------------
Summary: Implement Avro File statistic collector
Key: FLINK-27655
URL: https://issues.apache.org/jira/browse/FLINK-27655
Project: Flink
Issue Type: Sub-task
Reporter: Zheng Hu
Currently, the flink table store's avro file writer don't provide its File
statistic collector. So we have to use the generic FieldStatsCollector.
In fact, the correct direction is: Making all format writer has their own
FileStatsCollector, so that we can just parse the columnar statistic from the
file tailer, instead of comparing each column max-min when writing the records
into the columnar file.
In this way, I think we can just remove the FileFormatImpl class and
FieldStatsCollector class.
