org.teiid.dqp.message.RequestID

This class represents an identifier for a request. However, there are some differences in what constitutes "uniqueness" for a given RequestID that is based on context (where the id is used). The RequestID has 2 parts: connectionID, and executionIDFor the purposes of the RequestID, the combined representation is "connectionID.executionID" - this implies a scoping for the name parts. The connectionID specifies a particular connection that is making requests. Each connection generates a unique executionID for each request execution, so the executionID is only unique in the context of a connectionID.

When this class is used between client and server, the connectionID is implied and thus only the executionID part will be used. The server will qualify the executionID with a connectionID when it reaches the server.

RequestIDs are immutable so no setters exist. This allows hashcodes to be pre-computed for faster comparison in equals.

      // Create command context, used in rewriting, planning, and processing
        // Identifies a "group" of requests on a per-connection basis to allow later
        // cleanup of all resources in the group on connection shutdown
        String groupName = workContext.getSessionId();


        RequestID reqID = workContext.getRequestID(this.requestMsg.getExecutionId());
        
        Properties props = new Properties();
        props.setProperty(ContextProperties.SESSION_ID, workContext.getSessionId());
