hi folks, After a long road, we're getting very close to having tests proving that the Java and C++ Arrow implementations are binary compatible -- this will be an exciting major milestone for the project. If you haven't been following along recent JIRAs, the way these tests work is as follows:
1) Testing dataset is specified in JSON format 2) Producer library (e.g. Java) reads JSON into Arrow in-memory, then writes out to an Arrow file IPC binary format 3) Consumer library (e.g. C++) attempts to read both the JSON and the binary file yielded by the producer library. The consumer compares the in-memory schemas and columnar data structures and indicates whether they are binary-identical I found a couple initial incompatibilities in the file format implementations, cited here: https://github.com/apache/arrow/pull/211#issuecomment-262080545. Thanks Wes
