Recommend literature that will "shift the brain" from Sql thinking to Nosql

Question

SQL

The other day I tried to deal with mongo DB and came to the conclusion that I can’t imagine how I would store the data by transferring them from mysql to nosql. The articles I found partially displayed the functionality of this solution. But they did not answer the question “How to organize all this at the project level?”. Please advise books \ articles in Russian or English that can change sql thinking towards nosql. Preferably using mongo db or cassandra as an example. Thank you.

Answer 1

In my opinion, everything is simple here. If you can't figure out how your project data will be stored in NoSql databases, then you don't need a NoSql database in your project. NoSql is not SQL + goodies, NoSql is SQL - (minus) unnecessary functionality. Therefore, IMHO, books or articles of the content “Moving to MongoDB. For dummies" cannot be in nature.

Answer 2

Map-Reduce + nosqldb with support for microtransactions (many operations performed elementarily) is a good start. But the data model will have to be maintained by hand, including building reverse indexes and so on.
But without caching and a properly built system, you will lose 100% both in speed and in memory. Nosql helps to parallelize the task as much as possible and “fill up with iron”, but this should be done not as a replacement for sql, but from scratch, without looking back at the sql past.

Answer 3

And here is a good video where a friend tells how he developed a complex system first on Postgres, and then on CouchDb:

Answer 4

Look at the book on CouchDB, I don’t know how it can “shift thinking”, but it seemed to me that it was not bad. It's also free: guide.couchdb.org/

Answer 5

On monge here: Data Models
Carefully read, make examples. Video from previous answer - cool! See him also.
The general idea is to dump the data in one heap (denormalization) and make a minimum of requests to the storage.
