Migrating from WSO2 Stream Processor¶
The Streaming Integrator performs all functions that are also performed by WSO2 Stream Processor. It also has additional features to trigger integration flows in order to take action in response to results derived after analyzing data.
If you are currently using WSO2 Stream Processor to carry out any streaming integration/stream processing activities and want to carry them out in the Streaming Integrator, you can migrate your setup as follows:
Preparing to upgrade¶
The following prerequisites should be completed before upgrading.
- Make a backup of the SP 4.4.0 database and copy the
directory in order to backup the product configurations. - Download the Streaming Integrator from the Enterprise Integrator Home
Migrating Databases¶
To connect the Streaming Integrator to the same databases as WSO2 SP 4.4.0 so that the persisted data can be accessed, configure the data sources as follows:
- Configure the data sources in the
<SI_HOME>/conf/server/deployment.yaml
file the same way you have configured them in<SP_HOME>/conf/wso2/worker/deployment.yaml
file. - Configure the data sources in the
<SI__TOOLING_HOME>/conf/server/deployment.yaml
file the same way you have configured them in<SP_HOME>/conf/wso2/editor/deployment.yaml
file. -
Check the data source configured for Business Rules in the
<SP_HOME>/conf/wso2/dashboard/deployment.yaml
file, and configure that data source with the same parameter values in the<SI__TOOLING_HOME>/conf/server/deployment.yaml
file.Info
The Business Rules feature which was a part of the
Dashboard
profile of the Stream Processor is now shipped with Streaming Integrator Tooling. Therefore, configurations related to this feature are added in the<SI__TOOLING_HOME>/conf/server/deployment.yaml
file.
For the complete list of data sources configured for the Streaming Integrator, see Configuring Data sources.
Migrating Siddhi applications¶
To migrate the Siddhi applications that you have deployed in WSO2 SP 4.4.0, follow the procedure below:
-
Copy all the Siddhi applications in the
<SP_HOME/wso2/worker/deployment/siddhi-files
directory. -
Place the Siddhi applications you copied in the
<SI_HOME/wso2/server/deployment/siddhi-files
directory.
Testing the migration¶
Simulate a few events to the Siddhi applications deployed in the Streaming Integrator to test whether they are generating the expected results.
