Class Summary

Class	Description
BootstrapBaseFileSplit	Sub-type of File Split which encapsulates both skeleton and bootstrap base file splits.
BootstrapBaseFileSplit.WrapperFileSplit	Wrapper for FileSplit just to expose default constructor to the outer class.
BootstrapColumnStichingRecordReader	Stitches 2 record reader returned rows and presents a concatenated view to clients.
FileStatusWithBootstrapBaseFile	Sub-Type of File Status tracking both skeleton and bootstrap base file's status.
HiveHoodieTableFileIndex	Implementation of BaseHoodieTableFileIndex for Hive-based query engines
HoodieColumnProjectionUtils	Utility functions copied from Hive ColumnProjectionUtils.java.
HoodieCopyOnWriteTableInputFormat	Base implementation of the Hive's FileInputFormat allowing for reading of Hudi's Copy-on-Write (COW) tables in various configurations: Snapshot mode: reading table's state as of particular timestamp (or instant, in Hudi's terms) Incremental mode: reading table's state as of particular timestamp (or instant, in Hudi's terms) External mode: reading non-Hudi partitions NOTE: This class is invariant of the underlying file-format of the files being read
HoodieHFileInputFormat	HoodieInputFormat for HUDI datasets which store data in HFile base file format.
HoodieHFileRecordReader
HoodieParquetInputFormat	HoodieInputFormat which understands the Hoodie File Structure and filters files based on the Hoodie Mode.
HoodieParquetInputFormatBase	!!! PLEASE READ CAREFULLY !!! NOTE: Hive bears optimizations which are based upon validating whether FileInputFormat implementation inherits from MapredParquetInputFormat.
HoodieROTablePathFilter	Given a path is a part of - Hoodie table = accepts ONLY the latest version of each path - Non-Hoodie table = then always accept
HoodieTableInputFormat	Abstract base class of the Hive's FileInputFormat implementations allowing for reading of Hudi's Copy-on-Write (COW) and Merge-on-Read (MOR) tables
InputPathHandler	InputPathHandler takes in a set of input paths and incremental tables list.
InputSplitUtils
LocatedFileStatusWithBootstrapBaseFile	Sub-Type of File Status tracking both skeleton and bootstrap base file's status.
PathWithBootstrapFileStatus	Hacky Workaround !!! With the base input format implementations in Hadoop/Hive, we need to encode additional information in Path to track matching external file.
RealtimeFileStatus	With the base input format implementations in Hadoop/Hive, we need to encode additional information in Path to track base files and logs files for realtime read.
RecordReaderValueIterator<K,V>	Provides Iterator Interface to iterate value entries read from record reader.
SafeParquetRecordReaderWrapper	Record Reader for parquet.

Annotation Types Summary

Annotation Type	Description
UseFileSplitsFromInputFormat	When annotated on a InputFormat, informs the query engines, that they should use the FileSplits provided by the input format to execute the queries.
UseRecordReaderFromInputFormat	When annotated on a InputFormat, informs the query engines, that they should use the RecordReader provided by the input format to execute the queries.
