---------------------------------------
Summary: .Net: Improve Task-based async API efficiency with
promise-style tasks
Key: IGNITE-1791
URL: https://issues.apache.org/jira/browse/IGNITE-1791
Project: Ignite
Issue Type: Improvement
Components: interop
Affects Versions: 1.5
Reporter: Pavel Tupitsyn
Assignee: Pavel Tupitsyn
Fix For: 1.5
Currently we use TaskFactory.FromAsync to create tasks and return them from
API. This requires implementing IAsyncResult, which has a heavyweight
WaitHandle inside. TaskFactory then uses ThreadPool.RegisterWaitForSingleObject
to wait on that handle and set task completion.
Creating WaitHandle and waiting on it are redundant extra steps.
System.Threading.Task has internal API to create "promise-style" task and then
set it to completed state when needed.
