Clone your ETL job and make it incremental

After your ETL job has been created, it’s able to clone and embrace incremental information dealing with utilizing delta tokens.

To do that, you’ll need to change the job script instantly. You’ll modify the script so as to add a press release which retrieves the final delta token (to be saved on the job tag) and add the delta token worth to the to the request (or execution of the job), which is able to allow the Delta Enabled SAP OData Service when retrieving the information on the subsequent job run.

The primary execution of the job is not going to have a delta token worth on the tag; due to this fact, the decision can be an preliminary run and the delta token will subsequently be saved within the tags for future executions.

1. Go to the AWS Glue console.
2. Within the navigation pane beneath ETL Jobs select Visible ETL.
3. Choose the Materials Grasp Job, select Actions and choose Clone job.
   
4. Change the title of the job to Materials Grasp Job Delta, then select the Script tab.
5. You must add an extra python library that can deal with storing and retrieving the Delta Tokens for every job execution. To do that, navigate to the Job Particulars tab, scroll down and develop the Superior Properties part. Within the Python library path add the next path:
   s3://aws-blogs-artifacts-public/artifacts/BDB-4789/sap_odata_state_management.zip

6. Now select the Script tab and select Edit script on the highest proper nook. Select Affirm to verify that your job can be script-only.
   

Apply the next modifications to the script to allow the delta token.

1. 7. Import the SAP OData state administration library lessons you added in step 5 above, by including the next code to row 8.

   from sap_odata_state_management.state_manager import StateManagerFactory, StateManagerType, StateType

   

2. The following few steps will retrieve and persist the delta token within the job tags so it may be accessed by the following job execution. The delta token is added to the request again to the SAP supply, so the incremental modifications are extracted. If there isn’t a token handed, the load will run as an preliminary load and the token can be endured for the subsequent run which is able to then be a delta load.To initialize the sap_odata_state_management library, extract the connection choices right into a variable and replace them utilizing the state supervisor. Do that by including the next code to line 16 (after the job.init assertion).

Yow will discover the <key of MaterialMasterAttributes node> and the <entityName for Materials Attribute> within the present generated script beneath # Script generated for node Materials Grasp Attributes. Remember to change with the suitable values.

key = "<key of MaterialMasterAttributes node>"
state_manager = StateManagerFactory.create_manager(
    manager_type=StateManagerType.JOB_TAG, state_type=StateType.DELTA_TOKEN, choices={"job_name": args['JOB_NAME'], "logger": glueContext.get_logger()}
)
choices = {
    "connectionName": "GlueSAPOData",
    "entityName": "<entityName for Materials Attribute>",
    "ENABLE_CDC": "true"
}
connector_options = state_manager.get_connector_options(key)
choices.replace(connector_options)

3. 9. Remark out the prevailing script generated for node Materials Grasp Attributes by including a #, and add the next alternative snippet.

   <key of MaterialMasterAttributes node> = glueContext.create_dynamic_frame.from_options(connection_type="sapodata", connection_options=choices, transformation_ctx="<key of MaterialMasterAttributes node>")

4. To extract the delta token from the dynamic body and persist it within the job tags, add the next code snippet simply above the final line in your script (earlier than job.commit())

   state_manager.update_state(key, <key of MaterialMasterAttributes node>.toDF())

That is what your ultimate script ought to appear like:
