fix(icms-fnds): Sending event ledger events in async mode - #1581
Conversation
📝 WalkthroughWalkthroughThe service now submits deployment-stage events asynchronously and logs asynchronous failures. The repository also ignores the ChangesDeployment event dispatch
Editor artifact ignore rule
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to Deployment-stage events no longer block instance updates, but failures may be less observable, slow Event Ledger calls can consume shared asynchronous capacity, and event consumers may receive related events out of order. These behaviors should be addressed or explicitly accepted before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)

InstanceUpdateServiceinvokessendFunctionDeploymentStage(...)before state-change and audit events, butCompletableFuture.runAsync(...)returns before the deployment-stage request completes. These later events can therefore reach consumers first. If ordering is required, serialize dispatches per instance or add an ordering key and integration coverage.🤖 Prompt for AI Agents

- Around line 88-96: Update the exceptionally handler in
FunctionDeploymentStagesService to emit the same failure telemetry as
FunctionDeploymentStagesClient.sendFunctionDeploymentStage for client or
transport exceptions not already reported. Preserve the existing error log and
return behavior while invoking sendStageTelemetryEvent with the appropriate
failure context.
- Around line 85-87: Update the asynchronous Event Ledger dispatch in
FunctionDeploymentStagesService, around the CompletableFuture.runAsync call
invoking FndsStubService.sendFunctionDeploymentStage, to use the
application-managed bounded executor instead of the CompletableFuture common
pool. Reuse the existing lifecycle-managed executor dependency and preserve the
current asynchronous dispatch behavior.

This is unrelated to the change. Now that we have V3 enabled, why are we still doing this:
if (icmsConfigurationProperties.isFndsMessagesV1Enabled()) {
responseHttpCode = postMessageV1(message);
}
if (icmsConfigurationProperties.isFndsMessagesV2Enabled()) {
responseHttpCode = postMessageV2(message);
}

TL;DR
Any higher latencies or crashes or any other issues on the Event Ledger side should not affect main flow of ICMS. To avoid any kind of EL issues we are sending messages in async mode unblocking main flow immediately.
