Pavel Tupitsyn created IGNITE-6372: -------------------------------------- Summary: .NET: Direct offheap access Key: IGNITE-6372 URL: https://issues.apache.org/jira/browse/IGNITE-6372 Project: Ignite Issue Type: Improvement Components: platforms Reporter: Pavel Tupitsyn Priority: Minor
{{cache.get}} from .NET (thick client with in-process JVM) works currently like this: * Java {{cache.withKeepBinary().get()}}: copy a piece of unmanaged memory from off-heap to {{byte[]}} * Java {{BinaryWriter.write}}: copy {{byte[]}} to unmanaged memory * .NET {{BinaryReader.Read}}: deserialize object from unmanaged memory So there are two unnecessary memory copy operations. Ideally we should be able to pass off-heap pointer to .NET and read from there directly (this may be complicated due to page memory architecture where object can span across pages). At least we can try to eliminate first copy to {{byte[]}} and copy from page memory to a stream directly via some additional {{BinaryObject}} implementation. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
