Update Read and modify data

[katarinasupe]

• Add warning around aggregations: https://memgraph.com/docs/querying/read-and-modify-data#aggregating
• Add limiting around deletes: https://memgraph.com/docs/querying/read-and-modify-data#delete-data
• Ugly image at the beginning in dark mode

@katarinasupe to which image are you referring in the third bullet? This one?

[katarinasupe]

@kgolubic basically any image that does not look good in dark mode, such as the one above.

Got it. We will need a lot of new images. I'll talk with the Design team about this.

This is not a priority, but rather a note to be careful about this in the future as well.

Similar to clauses, I think this can be improved on the docs side rather than DX. We will focus on the best practices and improving in-depth knowledge on the performance optimization side. I will primarily update this page: https://memgraph.com/docs/querying/differences-in-cypher-implementations

Regarding a warning in aggregations: highly OLAP analytical queries are not well suited for graph databases. Graph databases are more suitable for a query with a single source and for extracting values from it.
