MongoDB: Approach for storing frequently modified arrays
0
Need a piece of advice for storing a large number of references between Mongo entities that are frequently updated.
Some background:
- 1 event can have 100-1000 logs.
- 1 event can have 1-10 assets associated (assignment object).
- Logs are created per asset per event.
- Query pattern: find all logs by assignment (eventId and assetId).
Entities with their relations:
EVENT <-1--------------N-> LOG
EVENT <-N--ASSIGNMENT--N-> ASSET
Mongo collections and documents:
event: { id, name, ... }
asset: { id, name, ... }
log: { id, eventId, metadata, ... }
assignment: { id, assetId, eventId, metadata, ... }
Here comes the question:
- What is the best way to store associations between logs and assignments (events and assets)? Note that those associations are updated frequently and concurrently.
Approach 1
Store logIds in assignment entity:
assignment: { id, assetId, eventId, logIds, ... }
Approach 2
Create a separate entity for holding a single reference between log and assignment:
assignmentLog: { assignmentId, logId }
Another approach ?
Any advice will be appreciated. Thanks.
