### Describe the enhancement requested We need to discuss the choice of dependency for working with Parquet and other file formats in the java-info library. In my opinion, out-of-core computation is currently only implemented in the `C++` library, while other language bindings (like `Spark`) primarily need to support ETL operations. Under this assumption, we should prefer **lightweight**, focused libraries that can handle Parquet efficiently without pulling in large dependencies. For example, using the [parquet-java library](https://github.com/apache/parquet-java) could be sufficient for our current needs. However, if we plan to support **Gremlin** querying directly in the Java library in the future, we may need to implement out-of-core query capabilities , such as filtering and projection at read time. In that case, [Apache Arrow](https://arrow.apache.org/docs/java/index.html) becomes a more compelling choice. Looking forward to your thoughts. ### Component(s) Java -- This is an automated message from the Apache Git Service.
