Runtime Integration High Level View Streams DataStage Job Job DSSource / DSSink Operator StreamsConnector TCP/IP Composite operators that wrap existing TCPSource/TCPSink operators
Streams Application (SPL) use com.ibm.streams.etl.datastage.adapters::*;composite SendStrings { type RecordSchema = rstring a, ustring b; graph stream<RecordSchema> Data = Beacon() { param iterations : 100u; initDelay:1.0; output Data : a="This is single byte chars"r, b="This is unicode"u; } () as Sink = DSSink(Data) { param name : "SendStrings"; } config applicationScope : "MyDataStage"; } • When the job starts, the DSSink/DSStage stage registers its name with the SWS nameserver
DataStage Job User adds a Streams Connector and configures properties and columns
DataStage Streams Runtime Connector • Uses nameserver lookup to establish connection (“name” + “application scope”) via HTTPS/REST • Uses TCPSource/TCPSink binary format • Has initial handshaking to verify the metadata • Supports runtime column propagation • Connection retry (both initial & in process) • Supports all Streams types • Collection types (List, Set, Map) are represented as a single XML column • Nested tuples are flattened • Schema reconciliation options (unmatched columns, RCP, etc) • Wave to punctuation mapping on input and output • Null value mapping
Tooling Scenarios • User creates both DataStage job and Streams application from scratch • Create DataStage job in IBM Infosphere DataStage and QualityStage Designer • Create Streams Application in Streams Studio • User wishes to add Streams analysis to existing DataStage jobs • From Streams Studio create Streams application from DataStage Metadata • User wishes to add DataStage processing to existing Streams application • From Streams Studio create Endpoint Definition File and import into DataStage
Streams to DataStage Import On Streams side, user runs ‘generate-ds-endpoint-defs’ command to generate an ‘Endpoint Definition File’ (EDF) from one or more ADL files User transfers file to DataStage domain or client machine User runs new Streams importer in IMAM to import EDF to StreamsEndPoint model Job Designer selects end point metadata from stage. The connection name and columns are populated accordingly. IMAM Streams command line or Studio menu EDF EDF ADL Xmeta ADL FTP
DataStage to Streams Import On Streams side, user runs ‘generate-ds-spl-code’ command to generate a template application that from a DataStage job definition The command uses a Java API that uses REST to query DataStage jobs in the repository The tool provides commands to identify jobs that use the Streams Connector, and to extract the connection name and column information The template job includes a DSSink or DSSource stage with tuples defined according to the DataStage link definition Streams command line or Studio menu Java API SPL Xmeta REST API HTTP
Availability • Streams Connector available in InfoSphere Information Server 9.1 • The Streams components available in InfoSphere Streams Version 3.0 in the IBM InfoSphere DataStage Integration Toolkit
