Implement a gRPC server using the language of your choice, delivery should be made in the form of a single Pull Request containing all your proposed changes.
The service consists of a single RPC endpoint Exists, which should return whether or not the kaiko platform supports a given pair on a given exchange.
You must use the following endpoint https://reference-data-api.kaiko.io/v1/instruments, in order to build the response rules.
Response rules are as follows:
- if we find a match for (
exchange_code,exchange_pair_code) the endpoint should returnYES - if we don't find a match for (
exchange_code,exchange_pair_code) the endpoint should returnNO - if we don't have any match for
exchange_codethe endpoint should returnUNKNOWN
- protobuf definition must not be modified (except for language-related changes such as options)
- client code written in go must not be modified and must be compatible with your implementation
- instructions on how to run your server locally must be provided
- response time must be under 100ms
- your implementation must be documented
- your implementation must be ready to be packaged in a docker image (Dockerfile must be implemented)
- your implementation must be integration-tested
- you should implement a build tool (Gradle, Rake, Make, etc.) to ease the build and testing of your implementation
- your commit history should be clean and reflect atomic changes, you are allowed to rewrite history
