Purpose

The total number of sprints, including closed sprints, in your instance can contribute to problems with the closedSprints() JQL function, and overall performance degradation related to slow sprint cache population. 

Solution

If you experience problems, use the following queries to check the total number of sprints, and identify the oldest sprints so they can be deleted if no longer required. 

Find the total number of sprints

Query tested on PostgreSQL and MySQL. You may need to adapt this query for other databases.  

SELECT count(*) 
FROM "AO_60DB71_SPRINT";

SELECT count(*) 
FROM AO_60DB71_SPRINT;

Find the oldest sprints

Query tested on PostgreSQL and MySQL. You may need to adapt this query for other databases.  

SELECT *, CAST(TO_TIMESTAMP("END_DATE"/1000) AS date) AS end_date_human_readable
FROM "AO_60DB71_SPRINT"
where "CLOSED" = true
order by "END_DATE";

SELECT * 
FROM AO_60DB71_SPRINT 
where CLOSED = true 
order by END_DATE
