Element Migration
See examples of how the Aleri elements migrate to CCL.
- StartUp Element Migration
In CCL, the Aleri StartUp element migrates to an ADAPTER START statement, and takes connection group references. You can assign connection groups to adapters in the ATTACH ADAPTER statements.
- DataLocation Element Migration
The Aleri DataLocation element does not migrate directly to CCL because CCL has no equivalent element. However, you can define all the Aleri DataLocation properties as CCL adapter properties in the ATTACH ADAPTER statement.
- Store Element
See how the store element migrates from AleriML to CCL.
- InConnection Element Migration
In CCL, the Aleri InConnection element migrates to an ATTACH INPUT ADAPTER statement, and the InConnection and DataLocation properties are defined as adapter properties. The Aleri store element migrates to a CREATE MEMORY STORE statement, and the SourceStream element migrates to a CREATE INPUT WINDOW statement.
- OutConnection Element Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement, the SourceStream element migrates to a CREATE INPUT WINDOW statement, and the OutConnection element migrates to an ATTACH OUTPUT ADAPTER statement.
- SourceStream Element
See how different cases of the SourceStream element migrate from AleriML to CCL.
- CopyStream Element
See how different cases of the CopyStream element migrate from AleriML to CCL.
- UnionStream with Stateful Store Migration
In this example, the Aleri UnionStream element has an attached stateful (memory) store and two input streams ("alldatatypes" and "alldatatypes1") that participate in a union operation. In CCL, the Aleri Store element migrates to a CREATE MEMORY STORE statement and the UnionStream element migrates to an output window with a UNION clause.
- FilterStream Element
See how different cases of the FilterStream element migrate from AleriML to CCL.
- ComputeStream with Stateful Store Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement and the ComputeStream element migrates to an output window. The value of the name attribute in the ColumnExpression element becomes the name of the column in the SELECT clause of the output window, and the value of the ColumnExpression element becomes the value in the SELECT clause.
- ExtendStream with Stateful Store Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement. Since the Aleri ExtendStream element extends all columns from its input stream, in CCL, it migrates to an output window with extended columns from the input stream.
- AggregateStream with Stateful Store Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement, and the AggregateStream element migrates to an output window. The value of the name attribute in the ColumnExpression element becomes the name of the column in the SELECT clause of the output window.
- JoinStream Element
See how different cases of the JoinStream element migrate from AleriML to CCL.
- Global Migration
In CCL, the Aleri Global element migrates to a DECLARE END statement.
- FlexStream Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement, and the FlexStream "compute" migrates to Flex element "Ccl_1_compute", with OUT as the output window "compute" and with the schema previously defined in AleriML. The method element migrates to an ON clause.
- PatternStream Migration
In CCL, the Aleri PatternStream "compute" migrates to output stream "Ccl_1_Pattern".
