Hello Friends,
I would like to understand how data is stored in the adobe experience cloud platforms.
I have studied and found that:
1. A dataset (like a table in SQL) is created with the JSON schema.
2. This definition of a dataset is stored in the catalog. This is not stored in the data lake.
3. Actual data is stored in the data lake.
4. With the query service, we can write a query in SQL format which can be converted into a format which understands by a data lake.
But I am not able to understand what is a data lake, and how the data is stored in the background.
If data lake is a Hadoop platform then data should be stored in a file form.
Can you please explain to me, how actual data is stored in the background and which database is being used to store it?
Note: I do not have access to experience platforms I am just reading documentation to understand it.
Thanks in advance.
Parvesh.
