Changes to JoinUtils.java: 1. Enhanced isScalarSubquery() method to detect scalar subqueries represented as Values nodes: - Added support for org.apache.calcite.rel.logical.LogicalValues - Added support for org.apache.drill.exec.planner.common.DrillValuesRelBase - Both check if tuples.size() <= 1 to identify scalar subqueries 2. Modified checkCartesianJoin() method to allow cartesian joins with scalar subqueries: - Added hasScalarSubqueryInput() checks for both INNER and non-INNER joins - Returns false (not a problematic cartesian join) when a scalar subquery is detected - Allows nested loop joins for scalar subqueries instead of throwing errors Reverted problematic changes: - DrillRexBuilder.java: Removed ensureType() override that added casts for nullability - DrillRelFactories.java: Removed nullability normalization in FilterFactory - DefaultSqlHandler.java: Removed extra logging Test results: - TestSetOp tests (testIntersectCancellation, testUnionFilterPushDownOverOr): PASSING - TestJoinNullable tests: PASSING - No regression in other tests --- .../exec/physical/impl/join/JoinUtils.java | 77 ++++++++++++++++++- 1 file changed, 76 insertions(+), 1 deletion(-) diff --git a/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java b/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java index d6b7fffa760..da8eb0856eb 100644 --- a/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java +++ b/exec/java-exec/src/main/java/org/apache/drill/exec/physical/impl/join/JoinUtils.java @@ -121,10 +121,20 @@ public static boolean checkCartesianJoin(RelNode relNode, List leftKeys RexNode remaining = RelOptUtil.splitJoinCondition(left, right, joinRel.getCondition(), leftKeys, rightKeys, filterNulls);

There are several methods for creating literals in {@link RexBuilder}: + * {@link RexBuilder#makeLiteral(boolean)} and so forth. + * + *

How is the value stored? In that respect, the class is somewhat of a black + * box. There is a {@link #getValue} method which returns the value as an + * object, but the type of that value is implementation detail, and it is best + * that your code does not depend upon that knowledge. It is better to use + * task-oriented methods such as {@link #getValue2} and + * {@link #toJavaString}. + * + *

Allowable types for RexLiteral instances
TypeNameMeaningValue type
{@link SqlTypeName#NULL}The null value. It has its own special type.null
{@link SqlTypeName#BOOLEAN}Boolean, namely TRUE, FALSE or + * UNKNOWN.{@link Boolean}, or null represents the UNKNOWN value

{@link SqlTypeName#DOUBLE}, + * {@link SqlTypeName#REAL}, + * {@link SqlTypeName#FLOAT}Approximate number, for example 6.023E-23.{@link Double}.
{@link SqlTypeName#DATE}Date, for example DATE '1969-04'29'{@link Calendar}; + * also {@link Calendar} (UTC time zone) + * and {@link Integer} (days since POSIX epoch)
{@link SqlTypeName#TIME}Time, for example TIME '18:37:42.567'{@link Calendar}; + * also {@link Calendar} (UTC time zone) + * and {@link Integer} (milliseconds since midnight)
{@link SqlTypeName#TIMESTAMP}Timestamp, for example TIMESTAMP '1969-04-29 + * 18:37:42.567'{@link TimestampString}; + * also {@link Calendar} (UTC time zone) + * and {@link Long} (milliseconds since POSIX epoch)

{@link SqlTypeName#BINARY}Binary constant, for example X'7F34'. (The number of hexits + * must be even; see above.) These constants are always BINARY, never + * VARBINARY.{@link ByteBuffer}; + * also {@code byte[]}
{@link SqlTypeName#SYMBOL}A symbol is a special type used to make parsing easier; it is not part of + * the SQL standard, and is not exposed to end-users.

DrillReduceExpressionsRule / ReduceAndSimplifyExpressionsRules: under schema-on-read a scan column is typed ANY and "=" is an implicit-cast comparison, not a type-strict equality. Calcite 1.42 propagates equality constants from pulled-up predicates more aggressively, rewriting a projected ANY column (e.g. the FLOAT8 `float` column) into the compared VARCHAR literal -- so "select float ... where float = '1.2'" returned the string "1.2" instead of the double 1.2. Both project reduce rules now strip ANY-column equality predicates before simplifying, so the column value is projected with its real type. Fixes TestFunctionsQuery.testImplicitCastVarcharToDouble. 2. TestSetOp.testIntersectWith / TestUnionAll.testUnionAllInWith: these queries join on a constant literal year_total (year_total = year_total), which is a genuine cartesian join. Calcite 1.42 correctly folds the constant join key and identifies the cartesian (earlier versions kept a redundant equi-join), so the queries now require Drill's non-scalar nested-loop join.

Several Drill schemas expose their sub-schemas lazily through getSubSchema(name) and do not enumerate them -- e.g. Cassandra keyspaces and Mongo databases -- so getSubSchemaNames() is empty and case-insensitive resolution finds nothing. Multi-level references such as cassandra.test_keyspace.employee then fail with "Object 'test_keyspace' not found within 'cassandra'", breaking essentially the entire Cassandra test suite (these worked under Calcite 1.38, which resolved sub-schemas via getSubSchema directly). AbstractSchema now overrides subSchemas() to keep the default name-based behaviour but fall back to a direct, lazy getSubSchema(name) resolution when no enumerated name matches.

The Delta plugin pushes filters down only to prune Parquet files conservatively (artificialFilter() == true): the pushed PluginFilterRel does not guarantee that the rows it returns satisfy the condition, so a residual Drill filter is kept on top to remove non-matching rows. When all files are pruned, the group scan keeps one file for schema and relies on that residual filter to yield zero rows. DrillRelMdPredicates.getPredicates(Filter) advertised the PluginFilterRel's condition as a pulled-up predicate. Calcite 1.42's stronger predicate inference then treats the residual filter as redundant and removes it, so the schema-placeholder file's row leaks through (the bug only surfaced with an explicit projection; SELECT * kept the filter via star-column renaming). Add a getPredicates(PluginFilterRel) overload that propagates only the input's predicates, so a pruning-only plugin filter no longer claims its condition holds on output. Non-artificial plugins (Mongo, Iceberg, Paimon, Drill-on-Drill) fully apply their pushed filters, so the only effect there is a minor loss of downstream predicate inference; their pushdown tests still pass. --- .../exec/planner/cost/DrillRelMdPredicates.java | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/exec/java-exec/src/main/java/org/apache/drill/exec/planner/cost/DrillRelMdPredicates.java b/exec/java-exec/src/main/java/org/apache/drill/exec/planner/cost/DrillRelMdPredicates.java index c7bbc7c6088..d7789e49e61 100644 --- a/exec/java-exec/src/main/java/org/apache/drill/exec/planner/cost/DrillRelMdPredicates.java +++ b/exec/java-exec/src/main/java/org/apache/drill/exec/planner/cost/DrillRelMdPredicates.java @@ -29,12 +29,26 @@ import org.apache.calcite.rex.RexBuilder; import org.apache.calcite.rex.RexUtil; import org.apache.calcite.util.Util; +import org.apache.drill.exec.store.plan.rel.PluginFilterRel; public class DrillRelMdPredicates extends RelMdPredicates { public static final RelMetadataProvider SOURCE = ReflectiveRelMetadataProvider .reflectiveSource(new DrillRelMdPredicates(), BuiltInMetadata.Predicates.Handler.class); + /** + * A plugin filter is pushed down to the storage/format plugin, but for some + * plugins (e.g. Delta Lake) it is only used to prune files conservatively and + * does not guarantee that the rows it returns satisfy the filter condition -- + * a residual Drill filter is kept to remove non-matching rows.
