Devsim

A simple benchmarking service that checks upsert and list performance on different databases. For now it supports only MongoDB and PostgreSQL

Plans to add the following databases:

• sqlite (native go driver)
• duckdb (just in case, it might be bad because it's better for OLAP)
• cassandra
• mysql
• couchbase

Requirements

TODO, but!

All dependencies will be covered by docker.

Architecture

This application contains just of two layers:

• External Layer that accepts http connections
• Store Layer that stores entities inside some store hidden by implementation for specific database.

During to simple logic, there is no need to add additional business-logic layer since its all about saving incoming metrics into database.

External Layer

Typically simple HTTP Server which allows to interact with application by the following handlers:

Handler	Request	Parameters	Description
Upsert metric	POST /api/v1/stats/{id}	{id} -- ID of the device. String. JSON-encoded body for stats (see below for model)	Upserts stats for the passed device
List metrics	GET /api/v1/stats		Lists all available metrics

Store Layer

Provides two methods to interacts with statistics:

• List - list available metrics;
• Upsert - update metric by device id.
