David Li created ARROW-4213: ------------------------------- Summary: [Flight] C++ and Java implementations are incompatible Key: ARROW-4213 URL: https://issues.apache.org/jira/browse/ARROW-4213 Project: Apache Arrow Issue Type: Bug Components: FlightRPC Reporter: David Li
A C++ client cannot request streams from a Java service, nor can it decode the schema from GetFlightInfo. Schema: in Java, GetFlightInfo encodes the schema directly via flatbuffers. C++ expects it to be encoded as an IPC message. This isn't a problem in Java as a method exists to decode such schemas, but in C++ the API for reading such a schema isn't really exposed. I'm willing to submit a patch for this, but it's not clear to me which scheme is preferred. Streams: in Java, DoGet starts with an ArrowMessage containing a schema. C++ does not expect this and segfaults when it tries to decode the message as a record batch. Based on the presentations I've seen, I think C++ is in the wrong here; I have a patch to fix this that I could clean up and submit. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
