I've been trying to use the C++ Arrow Flight Client in an application and been hitting a crash when querying a non-trivial dataset (about 360K rows). The dataset is a mix of data types (strings, integers, doubles, lists, and structs).
The application is a combination of native code and .NET code. The application spawns multiple processes and uses multiple threads, though I don't think the FlightClient gets shared across threads. I see crashes when querying this dataset. Occasionally the number of elements in one of the StringArrays returns does not match the number of rows reported in a FlightStreamChunkIterator. This doesn't appear to happen consistently in the same place but always happens when querying this data set. Are there any concurrency issues to be aware of when working with FlightClient in C++? -- *James Duong* Lead Software Developer Bit Quill Technologies Inc.
