I tried to set timeout for query in IoTDB. I changed the value of configuration file in iotdb-engine.properties like follows: But it seems to be same for every query. How can I set different timeout for queries?

CodePudding user response：

For queries that take too long to execute, IoTDB will forcibly interrupt the query and throw a timeout exception, as shown in the figure:

IoTDB> select * from root; Msg: 701 Current query is time out, please check your statement or modify timeout parameter.

The default timeout of a query is 60000 ms，which can be customized in the configuration file through the query_timeout_threshold parameter.

If you use JDBC or Session, we also support setting a timeout for a single query（Unit: ms）：

((IoTDBStatement) statement).executeQuery(String sql, long timeoutInMS) session.executeQueryStatement(String sql, long timeout)
