---------------------------------------
Summary: Implementations of BufferAllocator should handle Netty's
OutOfDirectMemoryError
Key: ARROW-1084
URL: https://issues.apache.org/jira/browse/ARROW-1084
Project: Apache Arrow
Issue Type: Task
Components: Java - Memory
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
Priority: Minor
Implementations of BufferAllocator.buffer(...) are expected to throw an
OutOfMemoryException if the buffer cannot be allocated. There are multiple
reasons for that:
- allocator exceeded it's memory limit
- Netty exceeded it's direct memory limit
- the System is enable to fulfill Netty's request for more direct memory
For now only the first case throws an OutOfMemoryException. The second throws
an OutOfDirectMemoryError, and the third an OutOfMemoryError with the "Direct
buffer memory" error message.
