Springtistics

A service to collect and summarize statistics.

Running

• For gradle local run, exec ./gradlew bootRun on root folder.
• To run on docker, exec docker build -t <container_name> . && docker run -p 8080:8080 <container_name> on root folder.
• Default port is 8080.

Usage

• Endpoints are complaint to the requirements:

1. GET /transactions to fetch summary
2. POST /traansactions to send statistics, with Content-Type=application/json header

Development notes

• Application is built with plain Java Spring Boot 2.0 and gradle. To build it on local, run ./gradlew build.
• To achieve better results on both endpoints, the summary calculation is made on a scheduled task inside TransactionService class. The scheduler rate can be reduced if we need some more real-time data when fetching summary data.
• Load tests were made using https://gatling.io/, and both scripts and results are available on src/test/resources
• Project is buildable on travis CI through github integration. See .travis.yml for details.
• Have fun using it, and give me your feedback :)
