[ https://issues.jboss.org/browse/JBRULES-2623?page=com.atlassian.jira.plug... ] Edson Tirelli commented on JBRULES-2623: ---------------------------------------- The initial goal of this work is to decouple window definition from window usage, allowing for different window types to be supported and reused among different rules. At this point, the goal is to support: * *time based windows*, both strict and non-strict. I.e., for a window time(1h), support both immediate propagation and propagation only after the window is full. * *length based windows*, strict and non-stritct. Support optional grouping expression. E.g. (pseudo-syntax): {code:title=example.drl|borderStyle=solid} // the following would create a window with the last 10 orders for each customer ID @o : Order() over length(10, $o.customerId) {code} * *batch time windows* (a.k.a., tumbling windows) * *batch length windows* (a.k.a., tumbling windows) At this point it is not clear yet if we can/should support modifiers "unique"/"distinct", "group-by" and "order-by". Proposed syntax would be: {code:title=drl.ebnf|borderStyle=solid} windowDeclaration := DECLARE WINDOW id annotation* lhsPattern (HAVING modifier)? END modifier := DISTINCT LEFT_PAREN expr RIGHT_PAREN {code} E.g.: {code:title=example.drl|borderStyle=solid} declare window ticks @simple( test ) $s : StockTick( source == "NYCE" ) over window:length(5, $s.symbol) from entry-point "stock tick stream" end {code} The usage in regular rules would be supported as a new "from" construct: {code:title=example.drl|borderStyle=solid} rule X when Company( $symbol : symbol ) acc( StockTick( symbol == $symbol, $p: price ) from window ticks, $avg : average( $p ) ) then // the average price of the last 5 stock ticks for company $symbol // in the NYCE is $avg end {code} -- This message is automatically generated by JIRA.
