-------------------------------
Summary: Allow different strategies to combine key values when
merging parquet files
Key: PARQUET-1951
URL: https://issues.apache.org/jira/browse/PARQUET-1951
Project: Parquet
Issue Type: Improvement
Components: parquet-cli
Reporter: satish
I work on Apache Hudi project. We store some additional metadata in parquet
files (key range in the file, for example). So the metadata is different in
different parquet files that we want to merge these files.
Here is what I'm thinking:
1) Merge command takes additional command line option: --strategy
<StrategyClassName>.
2) We introduce new strategy class in parquet-hadoop to keep the same behavior
as today.
We can extend that class and provide our custom implementation.
