-----------------------------------
Summary: [C#] MemoryAllocator.Allocate(length: 0) should not
return null
Key: ARROW-5277
URL: https://issues.apache.org/jira/browse/ARROW-5277
Project: Apache Arrow
Issue Type: Improvement
Components: C#
Reporter: Eric Erhardt
See the conversation
[here|https://github.com/apache/arrow/pull/3925#discussion_r281187184].
We should change MemoryAllocator to not return `null` when the requested memory
length is `0`. Instead, we should create a cached "NullObject" IMemoryOwner
that has a no-op `Dispose` method, and always returns `Memory<T>.Empty`.
This way consuming code doesn't need to check for `null` being returned from
MemoryAllocator.Allocate.
