IGNITE-27814 Introduce JobTarget.Partition to allow job execution on specific partitions

[rezataroosheh]

JobTarget.The Partition(QualifiedName tableName, int partitionId) method has been added, allowing users to route compute jobs directly to the primary replica of a specific partition.

Direct Partition Access: Allows advanced users to perform operations on a specific partition (e.g., maintenance, custom aggregations, or data cleanup) when the partition ID is already known.

API Completeness: Complements the existing BroadcastJobTarget.Table(), which targets all partitions by allowing a single targeted-partition execution.

Hi @ptupitsyn,

Unfortunately, I’ve submitted two requests through the self-service sign-in page to get an ASF account for contributing to Apache Ignite, but I haven’t received any response so far.

Similarly, I currently don’t have access to TeamCity. Could you please help me in this regard?

Pull request overview

Adds partition-targeted compute execution and table-partition broadcast targeting, enabling compute requests to be routed to a table partition’s primary replica for improved partition awareness and API completeness.

Changes:

• Introduces JobTarget.Partition(...) and client-side handling for partition-targeted compute execution (ClientOp.ComputeExecutePartitioned).
• Adds BroadcastJobTarget.Table(...) support to execute a job across all partitions of a table.
• Extends tests and fake server infrastructure to validate routing, error handling, and broadcast behaviors.

Hi @ptupitsyn, just wanted to check in — all the feedback has been addressed, and the broadcast-related code has been removed. Could you take another look when you get a chance? Also, I noticed that IGNITE-23987 (.NET: Support broadcast partitioned) is the natural follow-up to this work, and since I'm already deep in this area of the codebase, I'd love to take it on if you're open to reassigning it to me once this PR lands.
