 The TaosCursor class uses native connections for write and query operations. In a client-side multi-threaded scenario, this cursor instance must remain thread exclusive and cannot be shared across threads for use, otherwise, it will result in errors in the returned results.
 
+The best practice for TaosCursor is to create a cursor at the beginning of a query and close it immediately after use. Please avoid reusing the same cursor for multiple executions.
