Python: Add CLIENT SETNAME to Valkey/Redis connector for connection identification

[kuriangeorgebinu]

…dentification

Fixes #14038
Summary:

• Added client_name parameter to Redis.from_url() calls in RedisCollection class
• Added client_name parameter to Redis.from_url() calls in RedisStore class
• Client name set to 'semantic_kernel_vector_store_client' following the suggested naming pattern Why This Matters:
  When monitoring a Valkey server with multiple connected applications, CLIENT LIST shows each connection's name. Without a client name, operators cannot distinguish Semantic Kernel connections from other anonymous clients. This is especially important in production environments with ElastiCache where multiple services share the same Valkey cluster. Setting client_name sends a CLIENT SETNAME command on connection, making the connection identifiable in:
• CLIENT LIST output
• Monitoring dashboards (e.g., Valkey Admin)
• CloudWatch metrics (ElastiCache)

Automated Code Review

Reviewers: 4 | Confidence: 92%

✓ Correctness

This is a straightforward, correct change that adds client_name to the two Redis.from_url() calls where the library creates its own connection. The redis.asyncio.client.Redis.from_url() accepts **kwargs passed to the connection pool/constructor, and client_name is a standard redis-py parameter that issues CLIENT SETNAME on connect. When users provide their own redis_database instance, it is passed through unchanged (correct behavior). No correctness issues found.

✓ Security Reliability

This PR adds a static client_name parameter ('semantic_kernel_vector_store_client') to two Redis.from_url() calls for connection identification purposes. The change is minimal, uses a hardcoded constant string (no injection risk), and doesn't alter any connection logic or error handling. No security or reliability issues identified.

✓ Test Coverage

The PR adds client_name="semantic_kernel_vector_store_client" to two Redis.from_url() calls (in RedisCollection.__init__ and RedisStore.__init__), but includes no tests verifying the parameter is passed correctly. Existing unit tests in test_redis_store.py test initialization of both classes (e.g., test_vector_store_defaults, test_collection_init) and verify connection properties like host, but never assert client_name. Since the change is simple and unlikely to regress, this is a suggestion rather than a blocking issue.

✗ Design Approach

The change adds connection identification, but the current design hardcodes a single client name with no caller override. That is weaker than the existing configuration pattern used elsewhere in this repo for client/application identification, and it leaves all Semantic Kernel deployments reporting the same name instead of letting each service identify itself distinctly.

Flagged Issues

• The new client_name is hardcoded with no way for callers to override it (RedisCollection.__init__ and RedisStore.__init__ expose no parameter). The Cosmos connector in the same repo already follows a better pattern: accepting application_name from the caller and threading it into the client constructor. Consider making client_name configurable with the current literal as the default.
