Pavel Tupitsyn commented on IGNITE-7530:
----------------------------------------
We should consider throwing an exception from
{{PlatformMemoryStream.GetArray()}}. This API is misleading.
> .NET: Poor performance & excessive memory usage in GetAll and query cursors
> in binary mode

> {{GetAll}} and query cursors do not use {{BinaryReader.DetachNext}}. So in
> binary mode for each binary object in a stream we copy entire stream content,
> see {{BinaryReader.ReadAsBinary}}, which calls {{Stream.GetArray()}}, which
> causes copying in {{PlatformMemoryStream}}.
