ExpressionPredicates.Or	An OR predicate that can be evaluated by the FileInputFormat.
FileIndex	A file index which supports listing files efficiently through metadata table.
FileIndex.Builder	Builder for FileIndex.
IncrementalInputSplits	Utilities to generate incremental input splits MergeOnReadInputSplit.
IncrementalInputSplits.Builder	Builder for IncrementalInputSplits.
IncrementalInputSplits.Result	Represents a result of calling IncrementalInputSplits.inputSplits(org.apache.hudi.common.table.HoodieTableMetaClient, boolean).
StreamReadMonitoringFunction	This is the single (non-parallel) monitoring task which takes a MergeOnReadInputSplit , it is responsible for: Monitoring a user-provided hoodie table path. Deciding which files(or split) should be further read and processed. Creating the splits corresponding to those files. Assigning them to downstream tasks for further processing.
StreamReadOperator	The operator that reads the splits received from the preceding StreamReadMonitoringFunction.
