How to realize cache

[Andrii Strelka]

In order to reduce number of requests  from JIRA while auto-assignment, it would be reasonable to keep 30 minutes cache stored locally.  JIRA post-function will query local file instead of making new request. How to realize it?

Jira stores all data in lucene index, that is why I can not see a reason for you to make your own cache. Or what kind of requests do you mean?

Customer want It)

Nope.

The customer rarely knows what they really want.  They often tell you stuff that is totally wrong.

A good service provider will check that the customer really wants.  So. 

• What is the end goal? 
• You've said "in order to reduce the number of request from Jira while auto-assignment", which begs the questions
  • What requests from Jira?
  • What auto-assignment?
  • Why do you think you need to reduce the numbers?
• Why does the customer think they want this? 

[Andrii Strelka]

Request - via REST API we get the oncall user (from Pager Duty)
Auto-assignment - we assign issues for user that oncall now

Ok.

• What is the end goal? 
• Why do you think you need to reduce the numbers?
• Why does the customer think they want this?

There is a built in cache in Jira. You can use it. Here is more info:

Or you can use such products like Redis and so on.
