Classes in org.apache.druid.segment.nested used by org.apache.druid.segmentClassDescriptionValue to dictionary id lookup, backed with memory mapped dictionaries populated lazily by the supplied
DictionaryWriter.Defines storage format for 'auto' and json columns.Container to collect a set of sortedIndexedrepresenting the global value dictionaries of someNestedDataComplexColumn, to later use withDictionaryMergingIteratorto merge into a new global dictionaryUsed byAutoTypeColumnIndexerto build the value dictionary, which can be converted into aSortedValueDictionaryto sort and write out the values to a segment withValueDictionary.getSortedCollector(). -
Classes in org.apache.druid.segment.nested used by org.apache.druid.segment.columnClassDescriptionBase implementation for columns created with
AutoTypeColumnSchemaand handled withNestedCommonFormatColumnHandlerto allow ease of merge viaAutoTypeColumnMergerby providing a common implementation. -
Classes in org.apache.druid.segment.nested used by org.apache.druid.segment.nestedClassDescriptionImplementation of
NestedDataComplexColumnwhich uses aCompressedVariableSizedBlobColumnfor the 'raw'StructuredDatavalues and provides selectors for nested field columns specified by ordered lists ofNestedPathPart.Value to dictionary id lookup, backed with memory mapped dictionaries populated lazily by the suppliedDictionaryWriter.Binary serialization for nested field type info, translated into this compact format for storage in segments.Base class for writer of global dictionary encoded nested field columns forNestedDataColumnSerializer.Base implementation for columns created withAutoTypeColumnSchemaand handled withNestedCommonFormatColumnHandlerto allow ease of merge viaAutoTypeColumnMergerby providing a common implementation.Defines storage format for 'auto' and json columns.Basic serializer implementation for theNestedCommonFormatColumnfamily of columns.Serializer forNestedCommonFormatColumnwhich can store nested data.Describes the basic shape for any 'nested data' (StructuredData)ComplexColumnimplementation along with basic facilities for caching any columns created and methods for retrieving selectors for nested field columns.Container to collect a set of sortedIndexedrepresenting the global value dictionaries of someNestedDataComplexColumn, to later use withDictionaryMergingIteratorto merge into a new global dictionaryAccumulates the list of literal field paths and a rough size estimation forStructuredDataProcessor -
