Hi devs, we were using these only 4 DBs to make analytics aggregating datas from our ESB until version 6.3.0 ; ANALYTICS_CARBON_DB ANALYTICS_METRICS_DB ANALYTICS_EVENT_STORE_DB ANALYTICS_PROCESSED_DATA_STORE_DB
These were postgres databases. Now I see there are more then 10 databases preconfigured in the default analytics 6.4.0 config (conf/dashboard/deployment.yaml and conf/worker/deployment.yaml). Well, … this is suggesting me lot of questions. First of all, is it still recommended (like it is for ESB&DSS databases) to do *not* use local H2 databases in production environment ? This question comes because the 6.4.0 analytics seems to me to be used as it is, out of the box, lot of DBs and no documentation for a any configuration as it was for previous versions. If we need to create external DBs for all the stuffs, what exactly are each DB for ? Is there any migration tool and/or documentation about migrating from analytics 6.3.0 to 6.4.0 ? (https://docs.wso2.com/display/EI640/Upgrading+from+WSO2+EI+6.3.0 does't talk about that) Any matching between former 4 DBs and the 6.4.0 new ones ? Is there a way to keep (transfer into 6.4.0) datas we collected with previous analytics version ? Thanks, Bernard
