Wes McKinney created ARROW-57:
---------------------------------
Summary: Format: Draft data headers IDL for data interchange
Key: ARROW-57
URL: https://issues.apache.org/jira/browse/ARROW-57
Project: Apache Arrow
Issue Type: New Feature
Components: Format
Reporter: Wes McKinney
>From the mailing list discussion, we need to define the structure of data
>headers to describe a "page" of Arrow data. In Apache Parquet these are
>referred to as the data page headers and are separate from the schema metadata.
As part of this JIRA:
* Choose a technology (it need not be the only one, but it would be good to
have a reference tool) for representing the data page header in "serialized"
form (as can be stored in shared memory and interpreted by any system with
access to that memory). Google's Flatbuffers libraries has been discussed for
this use case.
* Draft IDL specification for the data headers
