Wes McKinney created ARROW-1860:
-----------------------------------
Summary: [C++] Add data structure to "stage" a sequence of IPC
messages from in-memory data
Key: ARROW-1860
URL: https://issues.apache.org/jira/browse/ARROW-1860
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
Currently, when you need to pre-allocate space for a record batch or a stream
(schema + dictionaries + record batches), you must make multiple passes over
the data structures of interest (and use e.g. {{MockOutputStream}} to compute
the size of the output buffer). It would be useful to make a single pass to
"prepare" the IPC payload for both sizing and writing to prevent having to make
multiple passes
