[Integration] Update turbodbc integration test to install a pinned version in the Dockerfile

integration/turbodbc/runtest.sh currently installs and tests the integration with a fork's branch. We should test against the official turbodbc release once Uwe's PR gets merged. The turbodbc install step should be...

[C++] Share more of the IPC testing utils with the rest of Arrow

3

Some APIs in `arrow/ipc/test-common.h` aren't really IPC-specific. Furthermore, `arrow/ipc/test-common.h` is already included in non-IPC tests. Those APIs should be moved to the Arrow-wide testing utilities. **Reporter**: [Antoine Pitrou](https://issues.apache.org/jira/browse/ARROW-5141) / @pitrou...

[C++] Test and benchmark libraries library search path subtly affected by installation

4

Test and benchmark binaries should always favor the local non-installed libarrow and libarrow_testing. ```bash $ cmake -GNinja -DARROW_BUILD_TESTS=ON .. && ninja $ ldd release/arrow-array-test libarrow_testing.so.14 => /home/fsaintjacques/src/db/arrow/cpp/build/release/libarrow_testing.so.14 (0x00007f8f2b79e000) libarrow.so.14 =>...

[C++] allow construction of ArrayBuilders from existing arrays

After calling Finish it may become necessary to append further elements to an array, which we don't currently support. One way to support this would be consuming the array to...

[C++] FlightDataStream should be higher-level

5

Currently, `FlightDataStream` is expected to provide `FlightPayload` objects. This requires the user to handle IPC serialization themselves. Instead, it could provide higher-level `FlightData` objects (perhaps a simple struct containing a...

[C++] See if possible to deduplicate dictionaries in IPC streams in some way

1

As follow-on work to ARROW-3144, there are cases where a dictionary may be shared by multiple fields in a RecordBatch. The presumption of `arrow::ipc::DictionaryMemo` is that there is a 1-to-1...

[C++] DictionaryBuilder provides information to determine array builder type at run-time

1

This is needed for Arrow GLib. In Arrow GLib, we need to determine how to wrap Arrow C++ `ArrayBuilder` at run-time. `ArrayBuilder` may be passed as a generic `ArrayBuilder` instead...

[Documentation] Migrate FAQ page to Sphinx / rst around release time
