[jira] [Created] (ARROW-1329) [C++] Define "virtual table"
interface
Wes McKinney created ARROW-1329:
-----------------------------------
Summary: [C++] Define "virtual table" interface
Key: ARROW-1329
URL: https://issues.apache.org/jira/browse/ARROW-1329
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
The idea is that a virtual table may reference Arrow data that is not yet available in memory. The implementation will define the semantics of how columns are loaded into memory.
A virtual column interface will need to accompany this. For example:
{code:language=c++}
std::shared_ptr<VirtualTable> vtable = ...;
std::shared_ptr<VirtualColumn> vcolumn = vtable->column(i);
std::shared_ptr<Column> = vcolumn->Materialize();
std::shared_ptr<Table> = vtable->Materialize();
{code}
