BellaDati Import Node is a dedicated module, which provides the Import and Transformation services. Import Nodes may run separately and independent on the main server to achieve faster import performance. |
| Tip |
|---|
Using Import nodes is recommended in following scenarios: - more than 10 imports running at the same time
- huge data processing and transformation is expected
- import frequency is less than 10 minutes
|
1. Before you begin- BellaDati Import Node is a Java application, it needs a proper JVM installed on the machine. See Java Requirements.
- BellaDati Import Node is communicating directly with the main server and needs the direct access to the reporting database.
- Running multiple Import Nodes on single server is supported.
2. Download BellaDati Import NodeBellaDati Import Node binary distributions are available on https://my.belladati.com portal under Downloads -> BellaDati Import Node. | Note |
|---|
Please make sure that the server time of BellaDati server and Import Node server is the same (e.g. UTC). |
Add the following parameter to the application.properties file of your belladati.war archive and redeploy it: | Code Block |
|---|
application.import.nodes=node1:2552,node2:2552,...,nodeX:2552 |
BellaDati Standalone users (installed by exe or dmg installers) can find the application.properties file in BellaDati installation directory (by default it's C:\Program Files\BellaDati, eventually /Applications/BellaDati). | Note |
|---|
Port 2552 must be opened and accessible by the BellaDati main server. node1, node2 etc. must be a valid hostname resolvable by the machine, where BellaDati is running or IP address |
Create the configuration file application.properties with the following content: | Code Block |
|---|
application.url=http://belladati_host
application.production-mode=true
application.secure-mode=true
# JDBC resource
jdbc.driverClassName=org.postgresql.Driver
jdbc.url=jdbc:postgresql://db_host:5432/belladati_db
jdbc.username=belladati_dbuser
jdbc.password=belladati |
5. Run BellaDati Import NodeExecute the following command: | Code Block |
|---|
java -Xmx2048m -Dconf=application.properties -Dimport.node.host=IP_OF_THE_HOST -Dimport.workers.size=10 -Dimport.node.name=import-node-1 -Done-jar.main.class=com.belladati.remote.ImportNodeMain -jar belladati-import-node.jar & |
| Note |
|---|
The IP_OF_THE_HOST parameter has to be replaced by the real IP address of the server, where BellaDati Import Node is running. |
To specify the port of the import node, there's parameter import.node.port which may be specified either in application.properties or as a java -D parameter ( e.g. -Dimport.node.port=2553 ) 6. Verify the Import Node installationYou can easily check, whether the import node is running properly by opening the Settings -> Import Node administration page directly in BellaDati UI. 
| Note |
|---|
If there are multiple import nodes, BellaDati will use the node which has more free workers. |
Since BellaDati 2.9.7, BellaDati will execute the import locally in case the import nodes are not available (e.g. because of network error). |
