Evaluating MongoDB for Write-Heavy, Scalable Workloads

Hello Community,
I’d like to understand whether MongoDB is suitable database for write-heavy work load or not. Current work load of my MongoDB is:

  • Daily Average Writes: ~404K (projected to increase to 500K–600K in the next month)
  • Daily Average Reads: ~30K (projected to increase to 30K–40K)

With above projection & stats I would like to understand following things:

  • How will MongoDB perform under this high write throughput workloads?
  • What things should we take into consideration if we are sticked to MongoDB as only our DB?
  • Whether should we look for alternative DBs, if yes then could this community is appropriate source for suggesting it?

I am just trying to evaluate whether my current MongoDB is right for long-term choice as Primary DB for my Product or not, because as time grows it will increase the data & write requests subsequently.

Appreciate your insights and experiences!
