Client-Server gRPC springboot applications

Server

Dummy Wallet app with deposit\withdraw\balance methods.

Prerequisites: docker

Run: ./gradlew :app:bootRun

Client

CLI test harness to wallet

Run: ./gradlew :cli:bootRun --args '1 1 1'

where args:

  • number of concurrent users emulated
  • number of concurrent requests a user will make
  • number of rounds each thread is executing

Solution side note

Assuming that concurrent access to the account is not common case, server relies on the optimistic locking for solving this problem: stale_state message will be returned to a client.

It's up to client how to deal with it. CLI-harness in this project will retry operations on stale_state result.

Performance testing

ghz command line benchmarking utility was used for performance testing. Example configs may be found in ghz-config folder.

Run: ghz-config> ./ghz --config deposit.json

Results on dev machine:

  • balance request ~2000 RPS
  • deposit\withdraw request ~700 RPS
