I need some step-by-step tutorial or some papers that I can learn how to create my own JSON schema mining tool. It would be great if someone can share sources or ideas. Thanks!

Technologies I am using to fetch data from my MySQL database is Spark 2.4.4 and Scala. I want to display that data in my Angular8 project. Any help on how to do it? I could not find any documentation regarding this.
I am not sure if this is a scala/spark related question. It sounds more towards system design of your project.
One solution is to use your Angular8 directly read from MySQL. There are tons of tutorials online.
Another solution is to use your spark/scala to read data and dump to CSV/JSON file at somewhere and use Angular8 to read in that file. The pros is that you can do some transformation before displaying your data. The cons is that there is latency between transformation and displaying. After reading the flat file into JSON it's up to you how to render that data on user's screen.
I have recently pulled multiple JSON files from a SQL database and I would like to load them into my Google Datastore. Can anyone suggest the best way to go about this. I have read the docs and they detail how to create entities but I cannot determine how to do a bulk data load. Any tips or tricks would be welcome.
Two years later and no answer! The key to doing this right now, in 2017, seems to be the new Dataflow thing in Google Cloud. There are SDKs for both Java and Python, but it's still so new I'm using the Java SDK, the 1.9 version. I've adapted two of the examples and have it putting data into the Datastore. It seems to play nice with namespaces so far, but it's a little difficult to make fields with parent/child relationships.
Can Graphhoper store and read data from a third party graph database like Titan (http://thinkaurelius.github.io/titan/) or a Tinkerpop Blueprints (http://www.tinkerpop.com/) compatible graph database?
There is old work regarding this issue here for Neo4J and tinkerpop. But this is no longer a priority and community contributions would be highly appreciated. E.g. import/export modules or an alternative GraphHopperStorage implementation would be interesting.
I'm working on a BI project where i'll use pentaho.
My DW will be modelize as a star schema.
I know that for the analysis part we need to go from this star schema (relational DW) and design the cube thks to schema workbench for example. Thks to that, the analysis tool can do the multidimensional request
For the reporting part, does It also need to know about the cube, or can I just do normal request on the star schema relational DW?
Is it a good or bad thing?
thks for your help
Cubes are for OLAP, which is interactive analysis with Pivot Tables
Your reporting tool, assuming it's not OLAP, should just talk directly to the data warehouse.
