  • Where CosmosDB falls short: autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used.
  • Where Prettier falls short: inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CosmosDB

  • Autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used
  • Provisioned throughput is charged in every region the account is replicated to, so multi region accounts multiply the RU bill
  • Storage charges cover data, indexes and backups in each replicated region
  • Egress out of Azure and between regions is charged, though ingress is free
  • The free allowance is one account per Azure subscription, limited to 1,000 RU/s and 25 GB
  • RU/s rates vary by region and are only shown through the pricing calculator rather than a flat published rate

Prettier

  • Inflexible style rules that cannot be customized significantly, forcing teams to accept opinionated defaults
  • Developers must format entire files rather than selective line ranges in some contexts
  • Limited language support compared to some alternatives, though it covers major languages
