Hi, Consider a situation, when doGet a ticket on arrow flight rpc server, the server retrieves several IPC upstreams (read parquet files through dataset api) and push into the same downstream, how to implement with less copies? Normally with one single IPC upstream, I'll direct start ServerStreamListener with the getVectorSchemaRoot of the reader of the upstream IPC. It seems that I have to deal with VectorSchemaRoot rather than ArrowRecordBatch directly. What is the proper impelmentation on popluating root to root? Is that correct use VectorLoad/Unloader? Does this introduce extra steps making immediate ArrowRecordBatch unnecessarily? (ArrowBuf -> VectorSchemaRoot@UpstreamReader -> ArrowBuf@Loader ->VectorSchemaRoot@DownstreamWriter -> ArrowBuf)
Maybe it relates to the allocator, is it any better implementations on same allocator? -- --------------------- Best Regards, Wenbo Hu,
