Pavel Tupitsyn updated IGNITE-5904:
-----------------------------------
Description:
Currently the only way to access array fields in {{IBinaryReader}} and
{{IBinaryRawReader}} is copying them entirely into a new instance:
{code}
byte[] ReadByteArray();
{code}
This does not allow reusing existing array (array pooling) or reading only a
part of the data (random access), which may hurt performance in certain use
cases.
Many .NET APIs provide an approach where existing array is used with index and
offset ({{Array.Copy}}, {{Socket.Receive}}, etc).
We can do a similar thing for *arrays of fixed-size elements* (byte, int, etc):
{code}
int ReadByteArray(byte[] dest, int destOffset, int srcOffset, int count);
{code}
