Task: Microservice Cache

The mission is to implement a java microservice that provide the functionality described by the OpenAPI spec included in the jar file.

The cache must have a specifc size and we must keep in that cache the values that are used recently. For example:

Cache size = 3

PUT(0, A)
PUT(1, B)
PUT(2, C)
PUT(3, D)

Cache content:

key, value
3, D
2, C
1, B

PUT(4, X)

Cache content: 
4, X
3, D
2, C

As you can see the (1, B) was removed because the cache size is actually 3

GET(2)

Cache content: 
2, C
4, X
3, D

As you can see the (2, C) was moved to top

PUT(5, J)

Cache content: 
5, J
2, C
4, X

As you can see (3, D) was removed because is the oldest in use

You should carry out the task according to the following instructions:

  1. Fork and clone this repo.
  2. Download TC-cache-api-0.0.1.jar TC-cache-api-0.0.1.jar
  3. execute mvn install:install-file –Dfile=TC-cache-api-0.0.1.jar -DgroupId=com.tc.cache -DartifactId=TC-cache-api -Dversion=0.0.1 for install the jar dependency in your local repository
  4. When done, submit (push) all your artifacts to the forked repo.

You must consider the following conditions when submitting the task:

  • Check that all the tests for the microservice passed (successfully)
  • Achieve an 80% of code coverage
  • We will check with this postman collection [TC - Cache.postman_collection.json](/external-sources/TC - Cache.postman_collection.json)
  • Write clean and well-structured code, whenever possible.
  • All the parts that can be variables (eg: cache size) must be in a configuration file.
  • If needed, include a readme file with further instructions to build and execute the microservice and its associated tests.
