class	CommitStream Sends a commit message to a SolrCloud collection
class	ComplementStream Emits tuples from streamA which do not exist in streamB.
class	DaemonStream
class	ExceptionStream
class	ExecutorStream The executor function wraps a stream with Tuples containing Streaming Expressions and executes them in parallel.
class	FacetStream The FacetStream abstracts the output from the JSON facet API as a Stream of Tuples.
class	FeaturesSelectionStream
class	FetchStream Iterates over a stream and fetches additional fields from a specified collection.
class	HashJoinStream Takes two streams (fullStream and hashStream) and joins them similar to an InnerJoinStream.
class	HavingStream The HavingStream iterates over an internal stream and applies a BooleanOperation to each tuple.
class	InnerJoinStream Joins leftStream with rightStream based on a Equalitor.
class	IntersectStream Emits tuples from streamA which also exist in streamB.
class	JDBCStream Connects to a datasource using a registered JDBC driver and execute a query.
class	JoinStream Defines a JoinStream which can hold N streams, all joined with the same equalitor
class	LeftOuterJoinStream Joins leftStream with rightStream based on a Equalitor.
class	MergeStream Merges two or more streams together ordering the Tuples based on a Comparator.
class	ModelStream The ModelStream retrieves a stored model from a Solr Cloud collection.
class	NullStream The NullStream Iterates over a TupleStream and eats the tuples.
class	OuterHashJoinStream Takes two streams (fullStream and hashStream) and joins them similar to an LeftOuterJoinStream.
class	ParallelStream The ParallelStream decorates a TupleStream implementation and pushes it to N workers for parallel execution.
class	PriorityStream The priority function wraps two topics that represent high priority and low priority task queues.
class	PushBackStream A TupleStream that allows a single Tuple to be pushed back onto the stream after it's been read.
class	RandomStream The RandomStream emits a stream of psuedo random Tuples that match the query parameters.
class	RankStream Iterates over a TupleStream and Ranks the topN tuples based on a Comparator.
class	ReducerStream Iterates over a TupleStream and buffers Tuples that are equal based on a comparator.
class	RollupStream
class	ScoreNodesStream Iterates over a gatherNodes() expression and scores the Tuples based on tf-idf.
class	SelectStream Selects fields from the incoming stream and applies optional field renaming.
class	SolrStream Queries a single Solr instance and maps SolrDocs to a Stream of Tuples.
