Has anyone here done benchmarks for native erlang data stores?

We’re investigating options for our use-case and I’d like to see if anyone has done the legwork to benchmark different native erlang data stores.

Would love to see findings and perhaps get guidance on what we need:

For us our core requirements revolve around

  • Optimized for small values ( like speed, position, velocity etc )
  • We are trying to limited writes to disk and preferably have writes manually triggered
  • Complex queries aren’t expected
  • Ideally want the ability to edit nested values (i.e edit A⇒ A.b⇒ A.b.c = 4)

So we are looking at CowDB as an option, wondering if anyone has monitored their disk usage around like ~10,000 cowdb reads&writes for different data stores that fit the bill?
