[TODO] Switch to Bit-Vectors for Access Control

[arg3t]

Description

Currently, access control is done via calculating a set of accesible notes and comparing notes with that. This does not scale. Instead, we could switch to a method that makes use of bit-vectors to calculate access levels.

Example

1. Each entity has a field access_id which stores its index in the access control vector
2. Each note has a dynamically calculated access_level value which is a Bit-Vector. (Possibly Propagated to Relationships)
3. Every time a query is made, an access control vector is calculated for the user (readable entities 1, non-readable 0)
4. This access vector is compared with the user's vector (similar to vector clocks)

Priority

• High
• Medium
• Low

Environment

• Component: Backend
• Version: v1.X.X

Expected Outcome

Faster query times for graph operations.
