CollationContext
DrillIndexDefinition
DrillIndexDescriptor
FunctionalIndexInfo FunctionalIndexInfo is to collect Functional fields in IndexDescriptor, derive information needed for index plan, e.g.
IndexableExprMarker The filter expressions that could be indexed Other than SchemaPaths, which represent columns of a table and could be indexed, we consider only function expressions, and specifically, CAST function.
IndexCallContext
IndexCollection Interface used to describe an index collection
IndexCollection.IndexCollectionType Types of an index collections: NATIVE_SECONDARY_INDEX_COLLECTION, EXTERNAL_SECONDARY_INDEX_COLLECTION
IndexConditionInfo
IndexConditionInfo.Builder
IndexDefinition Top level interface used to define an index.
IndexDefinition.IndexType Types of an index: PRIMARY_KEY_INDEX, NATIVE_SECONDARY_INDEX, EXTERNAL_SECONDARY_INDEX
IndexDescriptor IndexDefinition + functions to access materialized index(index table/scan, etc)
IndexDiscover
IndexDiscoverBase IndexDiscoverBase is the layer to read index configurations of tables on storage plugins, then based on the properties it collected, get the StoragePlugin from StoragePluginRegistry, together with indexes information, build an IndexCollection
IndexGroup Encapsulates one or more IndexProperties representing (non)covering or intersecting indexes.
IndexLogicalPlanCallContext
IndexPhysicalPlanCallContext
IndexPlanUtils.ConditionIndexed
IndexProperties IndexProperties encapsulates the various metrics of a single index that are related to the current query.
