📝 WalkthroughWalkthroughAdded the Azure Files connector to the catalog. Added overview, setup, action reference, trigger reference, examples, and a change-tracker guide. Added sidebar navigation. ChangesAzure Files documentation
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🟡 Moderate · up to The Azure Files change-tracker example currently contains compilation errors, can miss or duplicate file-change notifications under failure or concurrent scans, and includes a broken reference link.

Move all imports to the module import block.
The combined Ballerina example uses time:Utc and log:* without imports. It also places import ballerina/task; after module declarations. Add ballerina/log, ballerina/task, and ballerina/time to the initial import block, then remove the later task import.

Correct the event delivery semantics or defer state commitment.
Snapshot.observe stores the new state before onFileCreated and onFileModified run. reconcile removes state before onFileDeleted runs. If a downstream hook or the process fails after either mutation, the next delivery is suppressed. The implementation therefore does not provide the at-least-once semantics claimed at Line 233.
Document the derived events as at-most-once per in-memory snapshot, or add a pending-event and acknowledgement flow that commits state only after successful event processing.

Prevent stale sweep results from deleting newly observed files.
The sweep builds present from the remote listing before calling snapshot.reconcile. If the listener observes a new file after the listing starts, that path is absent from the stale present set. reconcile then removes the path and emits onFileDeleted. The next poll reports the file as created again.
Use a scan generation or timestamp boundary. Delete only entries observed before the scan began, or coordinate observation and reconciliation at a higher level.

| **Interval tuning.** The listener's poll and the sweep run on independent schedules; 5 seconds each makes a responsive demo. For large shares, lengthen both, and remember each tick lists the share, so the cost scales with the share's file count, not with how much changed. | ||
|
|
||
| **The scheduled alternative.** If you do not need events within seconds, you do not need a resident listener at all: the same snapshot-diff idea works as a bounded program that runs on a schedule, compares the share against a snapshot file saved by its previous run, logs the differences, and exits. The connector repository's [change tracker example](https://github.com/ballerina-platform/module-ballerinax-azure.storage.files/tree/main/examples/change-tracker) is exactly that shape, and as a bonus its persisted snapshot catches deletions across downtime, the one blind spot of the in-memory tracker above. Pick by latency: live events warrant the listener, periodic reconciliation warrants the scheduled run. |
