      "message": "feat(replica): support querying replica status via RESTful API (#2377)\n\nSometimes we need to know the current status of a replica. For example,\nduring **offline partition split**, after new partitions are generated locally,\nwe need to start the replica server to load the new partitions. Only after\nconfirming that all partition data has been successfully loaded can we\nrebuild the metadata and recover the Pegasus cluster. However, there is\ncurrently no reliable way to verify that *all partition data has finished loading*.\n\nThere are two possible approaches:\n\n1. **Check the replica server logs.**\n   For example, if we find `\"load replica successfully\"`, we assume the partition\nhas been loaded successfully; if we find `\"load replica failed\"`, we assume the\nloading failed.\n   However, the problem is that log files are automatically cleaned up once their\nsize or count exceeds certain thresholds. When there are a large number of\npartitions, the relevant logs might already be removed before we even start\nchecking whether the partitions were loaded successfully.\n\n2. **Wait for a fixed period of time.**\n   This approach is also impractical because we do not know when a partition\nstarts loading or how long it will take to load. At the same time, we cannot wait\nindefinitely.\n\nIf we could directly know the current status of a replica — such as whether it is\nstill loading or already serving — this problem would be much easier to solve.\nTherefore, this PR introduces a **RESTful API** to query the current status of a\nreplica.\n\nSince the HTTP service is started **before partition data loading begins**, it is\npossible to query the replica status from the replica server while partitions are\nbeing loaded.\n\nAn example usage of the RESTful API:\n\n```\nGET http://1.2.3.4:34801/replica/status?app_id\u003d1\u0026partition_index\u003d2\n```\n\nIf the partition is currently loading, the replica server will return the following\nresponse in JSON format:\n\n```\n{\"status\": \"LOADING\"}\n```\n\nThe currently supported statuses include:\n\n* `LOADING`: the replica is being loaded;\n* `NOT_FOUND`: the replica does not exist;\n* `CREATING`:  the replica is being created;\n* `SERVING`: the replica is serving;\n* `CLOSING`: the replica is being closed;\n* `CLOSED`: the replica has been closed;\n* `UNKNOWN`: the replica is in an unknown status."

If the sender socket does not call `connect()`,\nthen calling `remote_endpoint()` on the receiver socket will always fail.\n\nThe fix is to remove the logic that calls `remote_endpoint()` on the receiving side. This logic\nwas introduced in https://github.com/apache/incubator-pegasus/pull/1658 to handle cross-network\nscenarios (when the address in the message header differs from the actual socket connection\naddress, the non-forwarding path corrects it to a recognizable address). Since UDP is primarily used\nfor the heartbeat scenario, and `beacon_msg` already contains `from_node` and `hp_from_node`,\nthis logic can be removed."

In each stage,\nimages are built for multiple OS versions. If the src image build fails for **any** OS version,\nall bin image builds are canceled.\n\nIn practice, this is not ideal. The likelihood of build failures differs across OS versions —\nfor example, older OS versions are more prone to issues.

      "message": "perf(network): support client RPC connection pool to each server address (#2272)\n\n# 1. Motivation\n\nCurrently, for each remote server (\\\u003cip\\\u003e\\:\\\u003cport\\\u003e), at most one client connection\nis established, and all RPCs share this single connection. This approach is still\nacceptable when network latency is low, but it becomes problematic when the\nlatency is high (e.g., cross-country or intercontinental communication where latency\ncan exceed 100 ms). Since all RPCs share one connection, high network latency can\ncause one RPC to time out and fail, which in turn may lead to subsequent RPC failures.\nThis is especially critical for cases like duplication, where copying a checkpoint may\ninvolve transferring large amounts of data — high latency can make duplication almost\nimpossible.\n\nTo address this, we introduce a client connection pool for each remote server (\\\u003cip\\\u003e\\:\\\u003cport\\\u003e).\nThis allows better utilization of network bandwidth when there are many RPCs (each\npotentially involving large data transfers), reduces the risk of frequent RPC timeouts,\nand provides significant improvements in scenarios with high network latency.\n\n# 2. API\n\n## 2.1 Get Session\n\nThe most important interface of the connection pool is `get_rpc_session()`. External\ncallers only need to use this interface to obtain a session (i.e., a connection) from the\npool, without worrying about how the connection is created, connected, or reused.\n\n## 2.2 Callbacks\n\nWhen a session is successfully established (connection creation is generally asynchronous\nand will notify via a callback upon completion) or disconnected (I/O is generally asynchronous,\nand if an error is detected in a completion callback, the connection should be closed),\nthe pool’s `on_connected()` and `on_disconnected()` interfaces must be called to notify\nthe pool of these events.\n\n## 2.3 Close\n\nThe pool supports closing all sessions by `close()`. If a closed connection is still involved in\nI/O, it will trigger the disconnect callback, which in turn triggers the on_disconnected call.\n\n# 3. Implementation\n\nThe pool size—i.e., the maximum number of sessions it can hold—is configurable via\n`conn_pool_max_size`.\n\nWhen an external caller requests a connection from the pool, if the pool has not yet reached\nits limit, a new connection will be created and returned. Otherwise, an existing connection\nwill be selected and returned.\n\nEach connection may have multiple ongoing RPCs (or none at all). The selection strategy\nfor existing connections is to pick the one with the fewest in-flight RPCs.\n\n# 4. Changes\n\nCompared to before, the main change is moving from a single client connection to a client\nconnection pool. This change is almost seamless—code that previously fetched a single\nconnection now simply fetches one from the pool. Similarly, where the previous single\nconnection had its own callbacks (for connection established and disconnected) and close\nlogic, the corresponding pool interfaces should now be used.\n\nAdditionally, this PR includes optimizations and refactoring for much of the connection-oriented\nnetworking and RPC session (connection) code—without changing their behavior. Two new\nconfigurations, `socket_send_buffer_bytes` and `socket_recv_buffer_bytes`, have been\nadded to control the send/receive buffer size for each socket.\n\nFollowing configurations are newly added:\n```diff\n[network]\n+ conn_pool_max_size \u003d 4\n+ socket_send_buffer_bytes \u003d 16777216\n+ socket_recv_buffer_bytes \u003d 16777216\n```"

Upon receiving the\nrequest, the meta server attempts to look up the table name based on `app_id`\nand then performs ACL checks to verify whether the user has permission to\naccess the table. However, since `app_id \u003d -1` represents **all** tables rather\nthan a specific one, there is no corresponding table name to look up. As a result,\nthe lookup fails and the meta server returns an `ERR_INVALID_PARAMETERS`\nerror to the client.\n\nTo fix this issue, the meta server must first check whether `app_id \u003d\u003d -1` when it\nreceives a DDD diagnose request:\n- If `app_id \u003d\u003d -1`, the ACL check is deferred: the server first retrieves all DDD\npartitions and then performs ACL checks on each one individually, returning only\nthose partitions that the client user is authorized to access.\n- If `app_id !\u003d -1`, the `app_id` must correspond to a real table, so the existing logic\nremains unchanged: the server resolves the table name by `app_id` and performs a\nsingle and standard ACL check.\n\nIn addition to this root cause, several related issues were discovered and fixed as part\nof this change:\n- Changed the access type for `RPC_CM_DDD_DIAGNOSE` from `access_type::kControl`\nto `access_type::kList`, since the request only retrieves partition information and does\nnot modify any data or metadata.\n- The meta server previously handled only Ranger ACLs for the `RPC_CM_LIST_APPS`\nrequest, ignoring the legacy ACLs; this has now been fixed, where legacy ACLs are also\nrespected.\n- Refactored some ACL-related code for clarity and maintainability."

      "message": "perf(make_idempotent): introduce row lock to improve 2PC for idempotent atomic writes (#2214)\n\nhttps://github.com/apache/incubator-pegasus/issues/2197\n\nPreviously in https://github.com/apache/incubator-pegasus/pull/2198, we implemented\nidempotence for each atomic write by blocking the entire mutation queue until the 2PC\npipeline was drained. However, this significantly affects performance since the pipeline\nis stalled and all write requests get stuck in the mutation queue.\n\nTo address this performance issue, we introduce a row-lock mechanism: each hash key\nand the highest decree currently in the 2PC phase are recorded in a hash table. For each\natomic write request, if the maximum decree associated with its hash key has not yet been\napplied to the storage engine, the request is blocked in the mutation queue. Otherwise,\nthe hash key is considered unlocked and the request can proceed into the 2PC phase at\nany time.\n\nTo avoid the performance overhead of deserialization, we directly use the `partition_hash`\n(an unsigned 64-bit integer) from the client instead of the hash key. This also makes memory\nusage more predictable, as the `partition_hash` has a fixed size.\n\nAdditionally, to mitigate the performance impact caused by frequent insertions and deletions\nin the row-lock hash table, we introduce an LRU strategy: keys are only evicted when the hash\ntable exceeds a certain size threshold, and only the least recently used keys with no active\nusage are removed.\n\nGive a concrete example to illustrate how atomic write requests are handled after introducing\nrow locks. Suppose a client issues an `incr` request to a primary replica. If the primary replica\nhas been configured to make all atomic write requests idempotent, then:\n1. A mutation will be created as a blocking candidate to hold this atomic write request and then\nappended to the mutation queue.\n2. This mutation will be blocked and cannot get popped once the hash key contained in it is\nlocked(i.e. the maximum decree associated with the hash key has not been applied to the\nstorage engine).\n3. This mutation can get popped only after its hash key becomes unlocked.\n4. Popped from the mutation queue, the current base value 100 is read from the storage\nengine, and create a single put request to store the final value 101.\n5. Another mutation is then created to hold this idempotent single put request.\n6. Subsequently the new mutation enters 2PC phase, appended to `plog` and broadcast to\nsecondary replicas."
