We want to reverse the dependency between arrow-cpp and parquet-cpp. Thus parquet-cpp should depend on arrow-cpp and read/write to/from arrow memory.
There are two options the implementation could go ahead:
- Optionally depend on arrow-cpp and have some methods that read to arrow memory
- Strictly depend on arrow-cpp: This would avoid some code duplication between the two projects, i.e. we could use Arrow's allocator, I/O layer, utility classes instead of having our own ones in parquet-cpp which do exactly the same, just live in another namespace.
(I'll create some more JIRAs so we can proceed a bit more step-by-step but this one should be the one for coordination and discussions)
