Hi, All. Recently, Yakov opened issue: Criteria query to web console [1]
We can create criteria based filter that could be passed to ScanQuery over BinaryObjecs. I think it make sens to implement this filter as first-class citizen of org.apache.ignite.cache.query package and also support it from Web Console. But it could be re-used directly from code also. I think that we should implement a set of predicates to support AND, OR and NOT logical operations to group several predicates. We should support following operations: Numbers: ==, <, >, <=, >=, != Strings: equals, startsWith, endsWith, contains, matchRegExp (and also with IgnoreCase mode). Dates: ==, <, >, <=, >=, !=, between All: isNull, isDefined* *isDefined - Here I mean a check that some property is present in BinaryObject What do you think? If I missed some operations, please advice what could be added. Also, I think that a separate issue should be created for such "rules engine for BinaryObjects". Make sense?
