Jesus Camacho Rodriguez resolved CALCITE-2098.
----------------------------------------------
Resolution: Fixed
> Push filters to Druid Query Scan when we have OR of AND clauses
> ---------------------------------------------------------------
>
> Key: CALCITE-2098
> URL: https://issues.apache.org/jira/browse/CALCITE-2098
> Project: Calcite
> Issue Type: Bug
> Components: druid
> Reporter: slim bouguerra
> Assignee: slim bouguerra
> Priority: Major
> Fix For: 1.16.0
>
>
> Currently Druid Filter Rule doesn't push filters like {code} OR(AND(F1,F2),
> F3){code}
> This is due to optimization logic
> {code}org.apache.calcite.adapter.druid.DruidRules.DruidFilterRule.splitFilters{code}
> Here is an test example:
> {code}
> /**
> * @TODO Fix this case, Druid can handel this kind of expression but the way
> * org.apache.calcite.adapter.druid.DruidRules.DruidFilterRule.splitFilters
> * works doesn't accept this filter
> */
> @Ignore
> @Test public void testFilterClauseWithMetric2() {
> String sql = "select sum(\"store_sales\")"
> + "from \"foodmart\" where \"product_id\" > 1555 or \"store_cost\" >
> 5 or extract(year "
> + "from \"timestamp\") = 1997 "
> + "group by floor(\"timestamp\" to DAY),\"product_id\"";
> sql(sql)
> .queryContains(druidChecker("\"queryType\":\"groupBy\"",
> "{\"type\":\"bound\","
> +
> "\"dimension\":\"store_cost\",\"lower\":\"5\",\"lowerStrict\":true,"
> + "\"ordering\":\"numeric\"}"))
> .returnsUnordered("to be computed");
> }
> {code}
> FYI in this example {code} extract(year from \"timestamp\") = 1997{code} will
> be transformed to {code}(year >= 1996) AND(year <= 1997){code}
