Big Data Discovery Cloud Service (BDDCS) is an implementation of Big Data Discovery in the Oracle Cloud, whereas Big Data Discovery (BDD) is an on-premise implementation.
In BDDCS, you can use BDD as if you were to install Big Data Discovery on premise at your site. Here is the summary of a few differences between BDDCS and BDD on-premise implementation:
- A cluster of BDD nodes is not supported in BDDCS. The BDD on-premise implementation can be installed as a cluster, on more than one node in the Hadoop environment. Big Data Discovery Cloud Service (BDDCS) is hosted on a single BDCS node in your Big Data Cloud Service (BDCS) implementation in the Oracle Public Cloud.
- The Enterprise Manager plug-in and the
bdd-admin utility are not supported in BDDCS. To monitor the status of the BDDCS instance, start, stop, and back up it, use the BDDCS console in Oracle Cloud.
- Tuning of the Dgraph and HDFS flags and parameters is not supported in BDDCS. BDDCS is deployed with the Dgraph settings that let you use it out of the box, without having to tune Dgraph parameters, flags, location of logs, or log levels. You have full access to the logs for the Dgraph, Studio, Data Processing and HDFS Agent. To see any of the BDDCS component logs, access the BDDCS node in the BDCS cluster.
- In Studio, these differences exist between the Studio component in BDDCS and Studio in BDD:
- You can use a wide variety of Studio's data visualization and analysis components, and create your own visualizations with Studio's Custom Visualization Component extension, but Studio Component SDK for customization of existing Studio components is not supported in BDDCS.
- You can use all transformations available in Studio, and create your own transformation scripts in Studio's Transform editor, but extending the transform function library in Studio with custom, external Groovy scripts (to obtain additional "built-in" transform functions in Studio) is not supported in BDDCS.
- You can view all of the Studio settings in the Control Panel, but editing some of them is not supported in BDDCS. The BDDCS Administrator's Guide indicates those settings whose editing is allowed in BDDCS.
- In BDDCS, you cannot send emails of Studio's snapshot or bookmarks galleries. Also, email configuration in Studio's Control panel is disabled in BDDCS. Instead, to share Studio's snapshots and bookmarks with others, create additional Studio users who can view the same snapshots in Studio.
