Wes McKinney updated ARROW-1860: -------------------------------- Fix Version/s: (was: 0.10.0) 0.11.0 > [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 > Assignee: Wes McKinney > Priority: Major > Labels: pull-request-available > Fix For: 0.11.0 > > Attachments: text.html > > Time Spent: 10m > Remaining Estimate: 0h > > 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 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
