GetWorkerBuildIdCompatibilityAsync(string, int, RpcOptions?)

Use to retrieve the sets of compatible Build IDs for the targeted Task Queue. For more on this feature, see https://docs.temporal.io/workers#worker-versioning .

Task<WorkerBuildIdVersionSets?> GetWorkerBuildIdCompatibilityAsync(string taskQueue, int maxSets = 0, RpcOptions? rpcOptions = null)

Parameters

taskQueue string

The Task Queue to target.

maxSets int

The maximum number of sets to return. If not specified, all sets will be returned.

rpcOptions RpcOptions

RPC options.

Returns

Task<WorkerBuildIdVersionSets>

The sets, if the Task Queue is versioned, otherwise null.

GetWorkerTaskReachabilityAsync(IReadOnlyCollection<string>, IReadOnlyCollection<string>, TaskReachability?, RpcOptions?)

Determine if some Build IDs for certain Task Queues could have tasks dispatched to them. For more on this feature, see https://docs.temporal.io/workers#worker-versioning .

Task<WorkerTaskReachability> GetWorkerTaskReachabilityAsync(IReadOnlyCollection<string> buildIds, IReadOnlyCollection<string> taskQueues, TaskReachability? reachability = null, RpcOptions? rpcOptions = null)

Parameters

buildIds IReadOnlyCollection<string>

The Build IDs to query the reachability of. At least one must be specified.

taskQueues IReadOnlyCollection<string>

Task Queues to restrict the query to. If not specified, all Task Queues will be searched. When requesting a large number of task queues or all task queues associated with the given Build IDs in a namespace, all Task Queues will be listed in the response but some of them may not contain reachability information due to a server enforced limit. When reaching the limit, task queues that reachability information could not be retrieved for will be marked with a NotFetched entry in TaskQueueReachability. The caller may issue another call to get the reachability for those task queues.

reachability TaskReachability?

The kind of reachability this request is concerned with.

rpcOptions RpcOptions

RPC options.

Returns

Task<WorkerTaskReachability>

The reachability information.
