Deprecated ClassesClassDescriptionUse
SetOpNodeAs of 1.19, if you need to perform certain assertions regarding a RelNode tree and the contained traits you are encouraged to implement your own RelVisitor orRelShuttledirectly. The reasons for deprecating this class are the following:- The contract (Javadoc and naming) and the behavior of the class are inconsistent.
- The class is no longer used by any other components of the framework.
- The class was used only for debugging purposes.
As of 1.30.0, if you need to know how tables in a plan are accessed you are encouraged to implement your own logic (using a RelNode visitor or other). The class is not used anywhere in the project and remains untested thus it is deprecated.NowPlannerImplimplementsRelOptTable.ViewExpanderdirectly.This class is no longer needed; if you are writing a sub-class of Join that only accepts equi conditions, it is sufficient that it extendsJoin. It will be evident that it is an equi-join when itsJoinInfo.nonEquiConditionsis an empty list.UseRelMetadataQuery.org.apache.calcite.rel.core.RelFactories.TableScanFactoryImplhas calledRelOptTable.toRel(RelOptTable.ToRelContext).UseRelDataTypeField::getIndexUseRelDataTypeField::getNameNow Calcite is Java 8 and higher, we recommend that you implementPredicatedirectly.UseSqlLibraryOperatorTableFactory.getOperatorTable(SqlLibrary...)instead, passingSqlLibrary.ORACLEas argument.

Deprecated MethodsMethodDescriptionremove before Calcite 2.0Use
PhysType.convertTo(Expression, JavaRowFormat). The use of PhysType as a second parameter is misleading since only the row format of the expression is affected by the conversion. Moreover it requires to have at hand a PhysType object which is not really necessary for achieving the desired result.use NameMapuse NameSetUseLists.transform(java.util.List<F>, com.google.common.base.Function<? super F, ? extends T>)UseLists.transform(java.util.List<F>, com.google.common.base.Function<? super F, ? extends T>)andArrays.asList(Object[])FortraitSetOf(t1, t2), useRelOptCluster.traitSet()().replace(t1).replace(t2).UseRelOptPlanner.getCost(RelNode, RelMetadataQuery)or, better, callRelMetadataQuery.getCumulativeCost(RelNode).Previously, this method installed the cancellation-checking flag for this planner, but is now deprecated. Now, you should add aCancelFlagto theContextpassed to the constructor.UseRelMetadataQuery.Provide the expected clauses up-front, when you callSqlImplementor.visitInput(RelNode, int, Set), then create a builder usingSqlImplementor.Result.builder(RelNode).UseRelMetadataQueryviaRelOptNode.getCluster().UsegetColumnPairs().size()org.apache.calcite.rel.type.RelDataTypeFactoryImpl.useDoubleMultiplication(RelDataType, RelDataType) Replaced byRelDataTypeSystem.getMaxScale(org.apache.calcite.sql.type.SqlTypeName)(DECIMAL).From Calcite release 1.38 onwards, instead of calling this method, you should call
getMaxPrecision(DECIMAL).In Calcite release 1.38, if you wish to change the maximum precision of
SqlTypeName.DECIMALvalues, you should do two things:- Override the
RelDataTypeSystem.getMaxPrecision(SqlTypeName)method, changing its behavior forDECIMAL; - Make sure that the implementation of your
#getMaxNumericPrecisionmethod callsgetMaxPrecision(DECIMAL).
In Calcite release 1.39, Calcite will cease calling this method, and will remove the override of the method in
RelDataTypeSystemImpl. You should remove all calls to and overrides of this method.Replaced byRelDataTypeSystem.getMaxScale(org.apache.calcite.sql.type.SqlTypeName)(DECIMAL).From Calcite release 1.38 onwards, instead of calling this method, you should call

All non-standard time units are now parsed as identifiers, and resolved in the validator. You can define custom time frames usingRelDataTypeSystem.deriveTimeFrameSet(TimeFrameSet).
