Introduce support for liveness check for MSSQL CDC listener

[ayeshLK]

Purpose

$subject

Part of: ballerina-platform/ballerina-library#8589

Checklist

• Linked to an issue
• Updated the specification
• Updated the changelog
• Added tests
• Checked native-image compatibility

Summary

Adds liveness check support to the MSSQL CDC listener by extending internal listener configuration to include a configurable livenessInterval and refactoring how configurations are assembled and stored.

Changes

• Liveness support and configuration refactor:

  • Internal config map type changed from map to map to allow non-string values.
  • Introduced debeziumConfigs to collect Debezium, database, and MSSQL-specific settings; replaced prior configMap usage.
  • Built listenerConfigs as a shallow copy of debeziumConfigs and added a new livenessInterval field sourced from the config.
  • CdcListener.config is now a read-only clone of listenerConfigs.

• Dependency and packaging updates:

  • gradle.properties: multiple dependency version bumps (notably stdlibCdcVersion to 1.2.0-20260213-180200-2268a4d and several standard library bumps).
  • ballerina/Ballerina.toml and CompilerPlugin.toml: package version bumped to 1.16.3 and native/compiler-plugin artifact paths updated to SNAPSHOT versions.
  • ballerina/Dependencies.toml: multiple package version bumps and new package declarations (including avro, confluent.cavroserdes, confluent.cregistry, kafka, and mssql), which expand the project’s public dependency graph.

Impact

• No intended public API changes; the modifications are internal configuration and typing changes but may affect downstream code that relied on the previous internal config shape or typing.
• Checklist items not completed in this PR: updated specification, changelog, tests, and native-image compatibility verification.

📝 Walkthrough

Walkthrough

Refactors internal listener configuration to use map<anydata>, route population through a new debeziumConfigs map, create a shallow-copied listenerConfigs augmented with livenessInterval, and store it as a read-only config. Also bumps multiple dependency and manifest versions.

Changes

Cohort / File(s)	Summary
Configuration refactor ballerina/cdc_listener.bal	Changed internal config type from map<string> to map<anydata>. Introduced debeziumConfigs as the target for configuration population, replaced uses of the previous configMap, created listenerConfigs as a shallow copy with a new livenessInterval field, and set self.config to a read-only clone. Updated CdcListener field declaration to map<anydata> & readonly.
Gradle version updates gradle.properties	Bumped multiple dependency version properties (e.g., stdlibTime, stdlibLog, stdlibCdc, observe, crypto, task, http, etc.).
Package manifest bumps ballerina/Ballerina.toml, ballerina/CompilerPlugin.toml	Incremented package version (1.16.2 → 1.16.3) and updated referenced native/compiler plugin artifact paths to -1.16.3-SNAPSHOT.
Dependencies rework ballerina/Dependencies.toml	Added new packages (avro, confluent.cavroserdes, confluent.cregistry, kafka, mssql), bumped many package versions, removed several scope entries, and reorganized dependency graphs (notably cdc, confluent.*, and kafka integrations).

Poem

🐰 I hopped through maps both new and old,
Debezium buckets I neatly hold,
A listener wakes with liveness bright,
Read-only cloak for cosy night,
Version bumps—I'm bounding out of sight! 🎵

✅ Passed checks (4 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title 'Introduce support for liveness check for MSSQL CDC listener' directly corresponds to the main code change in cdc_listener.bal where livenessInterval is added to configuration.
Description check	✅ Passed	The description follows the template structure with Purpose and Checklist sections, includes a linked issue reference, and covers the core intent; however, Examples section is missing and most checklist items remain unchecked.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.

Please add/extend tests to assert that livenessInterval is included in the final listener config (including default/disabled scenarios).

🌐 Web query:

ballerinax CDC 1.2.0-20260213-180200-2268a4d published artifact

💡 Result:

I couldn’t find any publicly published artifact (Ballerina Central or otherwise indexed by web search) for ballerinax/cdc with the exact version 1.2.0-20260213-180200-2268a4d.

What is publicly visible on Ballerina Central right now is:

• ballerinax/cdc latest = 1.0.3 (and the “Other versions” list shown there does not include any 1.2.0-* build) [1].
• Related CDC components (e.g., ballerinax/mysql.cdc.driver) show latest versions like 1.0.1, not 1.2.0-* [2].

So that 1.2.0-20260213-180200-2268a4d identifier looks like an internal/nightly/CI build tag rather than a version that has been published to a public package repository.

Sources: [1], [2]

Replace the unstaged CDC version with a published release.

The version 1.2.0-20260213-180200-2268a4d is not published in any public repository. Ballerina Central shows ballerinax/cdc latest as 1.0.3. This timestamped identifier appears to be an internal/nightly build tag that will cause dependency resolution failures. Use a published version like 1.0.3 or configure a custom repository if this internal version is intentional.
