Import SAP Netweaver Gateway Data into Apache Solr

Use the CData JDBC Driver for SAP Netweaver Gateway in Data Import Handler and create an automated import of SAP Netweaver Gateway data to Apache Solr Enterprise Search platform.

The Apache Solr platform is a popular, blazing-fast, open source enterprise search solution built on Apache Lucene.

Apache Solr is equipped with the Data Import Handler (DIH), which can import data from databases and, XML, CSV, and JSON files. When paired with the CData JDBC Driver for SAP Netweaver Gateway, you can easily import SAP Netweaver Gateway data to Apache Solr. In this article, we show step-by-step how to use CData JDBC Driver in Apache Solr Data Import Handler and import SAP Netweaver Gateway data for use in enterprise search.

Create an Apache Solr Core and a Schema for Importing SAP Netweaver Gateway

  1. Run Apache Solr and create a Core. > solr create -c CDataCore For this article, Solr is running as a standalone instance in the local environment and you can access the core at this URL: http://localhost:8983/solr/#/CDataCore/core-overview
  2. Create a schema for the SAP Netweaver Gateway data to be imported. LastModifiedDate, if it exists in SAP Netweaver Gateway, is used for incremental updates. If it does not exist, you cannot do the deltaquery in the later section.
  3. Install CData SAP Netweaver Gateway JDBC Driver. Copy the JAR and license file (cdata.sapgateway.jar and cdata.jdbc.sapgateway.lic) to the Solr directory.
    • CData JDBC JAR file: C:\Program Files\CData\CData JDBC Driver for SAP Netweaver Gateway 2019\lib
    • Apache Solr: solr-8.5.2\server\lib

Now we are ready to use SAP Netweaver Gateway data in Solr.

Define an Import of SAP Netweaver Gateway to Apache Solr

In this section, we walk through configuring the Data Import Handler.

  1. Modify the Config file of the created Core. Add the JAR file reference and add the DIH RequestHander definition. solr-data-config.xml
  2. Next, create a solr-data-config.xml at the same level. In this article, we retrieve a table from SAP Netweaver Gateway, but you can use a custom SQL query to request data as well. The Driver Class and a sample JDBC Connection string are in the sample code below.
  3. In the query section, set the SQL query that select the data from SAP Netweaver Gateway. deltaQuery and deltaImportquery define the ID and the conditions when using incremental updates from the second import of the same entity.
  4. After all settings are done, restart Solr. > solr stop -all > solr start

Run a DataImport of SAP Netweaver Gateway Data.

  1. Execute DataImport from the URL below:
    http://localhost:8983/solr/#/CDataCore/dataimport//dataimport
  2. Select the "full-import" Command, choose the table from Entity, and click "Execute."
  3. Check the result of the import from the Query.
  4. Try an incremental update using deltaQuery. Modify some data in the original SAP Netweaver Gateway data set. Select the "delta-import" command this time from DataImport window and click "Execute."
  5. Check the result of the incremental update.
