SourceStream Element

See how different cases of the SourceStream element migrate from AleriML to CCL.

Example: SourceStream with Stateful Store Migration
In CCL, the Aleri store element migrates to a CREATE MEMORY STORE statement and the SourceStream element migrates to an input window.
Example: SourceStream with insertOnly Attribute Migration
The Aleri store element migrates to a CREATE MEMORY STORE statement. In CCL, streams are stateless and support only INSERT opcode, and windows are stateful and support all opcodes.
Example: SourceStream with FilterExpression Migration
In CCL, the Aleri store element migrates to the CREATE MEMORY STORE statement and FilterExpression migrates to a WHERE clause.
Example: SourceStream with autogen Attribute Migration
In CCL, nextval() is equivalent to the Aleri autogen attribute, and the Aleri store element migrates to a CREATE MEMORY STORE statement.
Example: SourceStream with InputWindow Migration
In CCL, the Aleri InputWindow element maps to the KEEP clause.
Example: SourceStream with Stateless Store Migration
In CCL, the Aleri SourceStream element with an attached stateless store migrates to an input stream element because streams are stateless in CCL.
