OrientDB分片分布式配置文件技术咨询：同类配置下Select查询可行性

Absolutely—many developers have used cluster setups similar to yours to run standard SELECT FROM ... queries, and your configuration has several practical patterns that are common in production environments. Let’s break this down:

First, here’s your configuration formatted for clarity:

{ 
  "autoDeploy": true, /* I've also tried setting this to false */
  "readQuorum": 1, 
  "writeQuorum": "majority", 
  "executionMode": "undefined", 
  "readYourWrites": true, 
  "newNodeStrategy": "static", 
  "servers": { "*": "master" }, 
  "clusters": { 
    "internal": { }, 
    "class_01": { "servers": ["n01"] }, 
    "class_02": { "servers": ["n01","n02"] }, 
    "class_03": { "servers": ["n03"] }, 
    "*": { "servers": ["<NEW_NODE>"] } 
  } 
}

Key Patterns That Support SELECT Queries #

• Low-Latency Read Setup: Your readQuorum: 1 setting means a SELECT query will return results as soon as one node responds—this is a popular choice for optimizing read performance in latency-sensitive applications. Pairing it with readYourWrites: true ensures that any writes you’ve just made are immediately available in subsequent reads, which is critical for use cases like user dashboards or real-time analytics.
• Cluster Segmentation: Grouping nodes into class_01, class_02, and class_03 is a common strategy for workload isolation. For example, you might route read-heavy reporting queries to class_03 (running on n03) to avoid impacting transactional traffic on class_01/class_02. Many teams use this approach to scale read operations without overloading core nodes.
• Static Node Management: The newNodeStrategy: "static" setting means new nodes won’t auto-join your clusters—this is typical in environments where you need strict control over node membership (e.g., for compliance or security reasons). Developers regularly run SELECT queries in these static setups, as long as cluster routing is properly configured to target the right nodes.

Things to Verify for Reliable SELECT Execution #

• Double-check the executionMode: "undefined" value: Most cluster tools fall back to a default execution mode when this is unset, but you’ll want to confirm that the default supports read operations. Some tools might require explicitly setting this to something like "read-only" or "read-write" for clarity.
• When autoDeploy is false, ensure all node configurations are manually synced: If you update cluster settings, you’ll need to push those changes to every node to avoid routing issues where queries can’t reach the intended servers.
• Test wildcard cluster routing: The * cluster pointing to <NEW_NODE> should be validated to ensure that when new nodes are added, they’re properly initialized with data—otherwise, SELECT queries routed here might return incomplete or inconsistent results.

In short, this type of configuration is absolutely viable for running SELECT queries, and many teams use similar setups to balance performance, control, and workload isolation.
