Interface Summary

Interface	Description
ByteBufferInputRowParser
Committer	Committer includes a Runnable and a Jackson-serialized metadata object containing the offset
Firehose	Deprecated.
FirehoseFactory<T extends InputRowParser>	Deprecated.
HandlingInputRowIterator.InputRowHandler
InputEntity	InputEntity abstracts an input entity and knows how to read bytes from the given entity.
InputEntity.CleanableFile	CleanableFile is the result type of InputEntity.fetch(java.io.File, byte[]).
InputEntityReader	InputEntityReader knows how to parse data into InputRow.
InputFormat	InputFormat abstracts the file format of input data.
InputRow	An InputRow is the interface definition of an event being input into the data ingestion layer.
InputSource	InputSource abstracts the storage system where input data is stored.
InputSourceFactory	An interface to generate a SplittableInputSource objects on the fly.
InputSourceReader	InputSourceReader reads data from InputSource and returns a CloseableIterator of InputRows.
InputStats	Tracks bytes read from an input source.
Row	A Row of data.
SplitHintSpec	In native parallel indexing, the supervisor task partitions input data into splits and assigns each of them to a single sub task.

Class Summary

Class	Description
AbstractInputSource	Abstract class for InputSource.
BytesCountingInputEntity	Wrapper around an InputEntity that counts the number of bytes read.
ColumnsFilter	Used by some InputSourceReader implementations in order to know what columns will need to be read out of the InputRow objects they create.
ColumnsFilter.ExclusionBased
ColumnsFilter.InclusionBased
FilePerSplitHintSpec	Assigns each input file to its own split.
HandlingInputRowIterator	Decorated CloseableIterator that can process rows with HandlingInputRowIterator.InputRowHandlers.
InputFileAttribute	A class storing some attributes of an input file.
InputRowListPlusRawValues	A triple of a list of InputRows, a Map of raw values, and a ParseException.
InputRowSchema	Schema of InputRow.
InputSplit<T>	Input unit for distributed batch ingestion.
IntermediateRowParsingReader<T>	InputEntityReader that parses bytes into some intermediate rows first, and then into InputRows.
ListBasedInputRow	Input row backed by a List.
ListBasedInputRowAdapter	Adapter for reading ListBasedInputRow.
MapBasedInputRow
MapBasedRow
MaxSizeSplitHintSpec	A SplitHintSpec that can create splits of multiple files.
RetryingInputEntity
Rows
SegmentsSplitHintSpec	SplitHintSpec for IngestSegmentFirehoseFactory and DruidInputSource.
StringTuple	Represents a tuple of String values, typically used to represent (single-valued) dimension values for an InputRow.
