Pavel Pereslegin resolved IGNITE-16233.
---------------------------------------
Resolution: Won't Fix
> Improve public API for setting caller context to service proxy.
> ---------------------------------------------------------------
>
> Key: IGNITE-16233
> URL: https://issues.apache.org/jira/browse/IGNITE-16233
> Project: Ignite
> Issue Type: Sub-task
> Components: managed services
> Reporter: Pavel Pereslegin
> Priority: Major
> Fix For: 2.13
>
>
> *Motivation.*
> When retrieving a proxy service, the user can specify optional parameters:
> {{timeout}} and {{sticky}}.
> When adding a new optional parameter (in discussed case - "context"), for the
> convenience of the user, several methods are added at once (with a different
> set of optional parameters).
> Thus, the number of methods can grow geometrically with the addition of each
> new parameter.
> *Suggested options:*
> # Add a new {{ServiceProxyConfiguration}} class which will combine all proxy
> settings.
> {code:java}
> ignite.services().serviceProxy(new ServiceProxyConfiguration(name,
> cls).setContext(callCtx));
> {code}
> {color:#DE350B}Adds yet another "config" object, complicates the use of
> the API.{color}
> # Add a new method "withContext(callCtx)" ({{returns IgniteServices}}) to the
> {{IgniteServices}} interface.
> {code:java}
> Ignite.services().withContext(callCtx).serviceProxy(name,...)
> {code}
> {color:#DE350B}Most of the {{IgniteServices}} methods are not related to the
> service call context (deploy, cancel of the service, etc. which may be
> confusing for the user). It's not clear what to do with the "timeout" and
> "sticky" parameters.{color}
> # Add a new "withContext(callCtx)" method which returns a new interface
> {{IgniteServiceProxies}} (name can be changed).
> {code:java}
> Ignite.services().withContext(callCtx).serviceProxy(name,...)
> {code}
> {color:#DE350B}The new interface has a not very clear purpose and naming
> (looks like "service proxy builder"). May be confusing for the user. It's not
> clear what to do with the "timeout" and "sticky" parameters.{color}
