You’ll use Spark Streaming or Spark SQL with Knowledge Lake, which means that you’ll be able to procedure huge quantities of information with no need to transport them into any other device first (like Hive) prior to processing them or doing analytics on them
Knowledge Hub – a spot to assemble information from all resources.
Knowledge Hub is a central position the place information is saved, processed, and analyzed for the venture. A Knowledge Hub structure supplies an built-in view of all information resources inside of a company.

Relying on how a lot processing energy you wish to have (or need) at any given time will decide which kind(s) would paintings best possible for a given scenario(s). If we’re speaking purely about dimension, then there isn’t in reality any distinction between them but when we have been having a look at efficiency, then relational databases would possibly be offering higher velocity since they have already got a construction constructed into their design, whilst NoSQL databases don’t require schema adjustments which means that much less overhead when writing new entries into database tables.
Knowledge Hub vs Knowledge Lake: how are they other from one any other?
A Knowledge Hub structure is a centralized repository that retail outlets the uncooked information and metadata, whilst an information lake is an enterprise-wide repository of all forms of uncooked information.

You wouldn’t be expecting each unmarried
The most suitable choice can be to have each, Knowledge Lake for the venture and Knowledge Hub for people.
Each are very other of their method against information control and analytics. Knowledge Hub comes with a number of benefits over the Knowledge Lake. It’s more effective to make use of, has an more uncomplicated interface, helps quicker information ingestion, and has higher-end efficiency than a Knowledge Lake. On the other hand, a few of these benefits do come at a price; for instance, you received’t be capable to use it in case your corporate doesn’t need or want to retailer huge quantities of historic information (as in lots of circumstances).
The most suitable choice can be to have each, Knowledge Lake for the venture and Knowledge Hub for people.
