| org.apache.druid.segment | |
| org.apache.druid.segment.nested | |
| org.apache.druid.segment.virtual |
| Class and Description |
|---|
| GlobalDictionarySortedCollector
Container to collect a set of sorted
Indexed representing the global value dictionaries of some
NestedDataComplexColumn, to later use with DictionaryMergingIterator
to merge into a new global dictionary |
| GlobalDimensionDictionary
Used by
NestedDataColumnIndexer to build the global value dictionary, which can be converted into a
GlobalDictionarySortedCollector to sort and write out the values to a segment with
GlobalDimensionDictionary.getSortedCollector(). |
| NestedLiteralTypeInfo.MutableTypeSet |
| StructuredData |
| StructuredDataProcessor |
| Class and Description |
|---|
| CompressedNestedDataComplexColumn
Implementation of
NestedDataComplexColumn which uses a CompressedVariableSizedBlobColumn for the
'raw' StructuredData values and provides selectors for nested 'literal' field columns. |
| GlobalDictionaryEncodedFieldColumnWriter
Base class for writer of global dictionary encoded nested literal columns for
NestedDataColumnSerializer. |
| GlobalDictionaryIdLookup
Ingestion time dictionary identifier lookup, used by
NestedDataColumnSerializer to build a global dictionary
id to value mapping for the 'stacked' global value dictionaries. |
| GlobalDictionarySortedCollector
Container to collect a set of sorted
Indexed representing the global value dictionaries of some
NestedDataComplexColumn, to later use with DictionaryMergingIterator
to merge into a new global dictionary |
| LocalDimensionDictionary |
| NestedDataColumnMetadata |
| NestedDataComplexColumn
Describes the basic shape for any 'nested data' (
StructuredData) ComplexColumn implementation along
with basic facilities for caching any columns created and methods for retrieving selectors for nested literal field
columns. |
| NestedDataComplexTypeSerde |
| NestedLiteralTypeInfo
Binary serialization for nested field type info, translated into this compact format for storage in segments.
|
| NestedLiteralTypeInfo.MutableTypeSet |
| NestedLiteralTypeInfo.TypeSet |
| NestedPathPart |
| StructuredData |
| StructuredDataProcessor.ProcessResults
Accumulates the list of literal field paths and a rough size estimation for
StructuredDataProcessor |
