Java Siddhi是否无法按多个变量分组？

我有以下流定义：

字符串eventStreamDefinition= 定义流cdrEventStream节点ID字符串、电话字符串、时间戳长度、isOutgoingCall bool

以及查询：

String query=@infoname='query1'来自cdrEventStreamwindow。externalTimetimeStamp，5秒选择nodeId，phone，timeStamp，isOutgoingCall，countnodeId作为callCount group by phone，isOutgoingCall将所有事件插入outputStream

但当我试图编译它们时，我得到：

org.wso2.siddhi.query.compiler.exception.SiddhiParserException: You have an error in your SiddhiQL at line 1:267, extraneous input ',' expecting {'#', STREAM, DEFINE, TABLE, FROM, PARTITION, WINDOW, SELECT, GROUP, BY, HAVING, INSERT, DELETE, UPDATE, RETURN, EVENTS, INTO, OUTPUT, EXPIRED, CURRENT, SNAPSHOT, FOR, RAW, OF, AS, OR, AND, ON, IS, NOT, WITHIN, WITH, BEGIN, END, NULL, EVERY, LAST, ALL, FIRST, JOIN, INNER, OUTER, RIGHT, LEFT, FULL, UNIDIRECTIONAL, YEARS, MONTHS, WEEKS, DAYS, HOURS, MINUTES, SECONDS, MILLISECONDS, FALSE, TRUE, STRING, INT, LONG, FLOAT, DOUBLE, BOOL, OBJECT, ID_QUOTES, ID}

要编译查询，唯一的方法是从GROUPBY子句中删除isOutgoingCall。Siddhi文档指出，应该可以通过多个变量进行分组。这是虫子吗

这在版本3.0.0-alpha上。Siddhi 3.0.0支持通过多个变量进行分组。我刚刚用Siddhi 3.0.0检查了您的查询，并且能够编译它。当然，我用的是3.0.0版。你能试试吗

提示：您可以使用在插入后按分组来轻松尝试查询

。。。进入outputStream？不，不起作用。无论如何，通过升级到3.0.3解决了这个问题。谢谢
