The number of data sets in any Hadoop data lake can be huge. Big Data Discovery provides the visual face to Hadoop. In Studio's Catalog, you can use search and Guided Navigation to find data sets and existing projects relevant to your analytical purpose.
After you log in, you see the
Catalog:
Here, you can:
- Find data sets
- Find existing projects
- Add a data set to BDD
This area lets you take a quick look at a data set, using
Preview.
Preview relies on the data set’s enriched metadata
to provide a summary. It gives you enough information to help you decide if
you'd like to move to the exploration phase:
Through Catalog, you can:
- Browse through your Hadoop cluster to discover relevant data sets based on name, metadata, attribute names, topics, dates, locations, or key terms.
- Search, filter, and use Guided Navigation to find the data sets.
- Find out which other data sets might be useful or interesting based on your interests, overlap in values, and activity of others.
- Use the same experience familiar to you from browsing online commerce sites, for searching and using Guided Navigation on discovered data sets.
As an outcome of this workflow, you find the data sets and projects you need for your analysis.
