Atlassian Reworks Jira Search to Handle Nearly 6 Million Software Versions

Atlassian engineers scaled Jira Search to support nearly 6 million software release versions, driven by customers whose largest instances track millions of releases. The original design loaded versions into memory and filtered them there, which made even preparing a search query a bottleneck at that scale. The post describes how the team addressed this performance limit.

Why it matters: Teams running large Jira instances will see how Atlassian tackled search performance at scale, which can inform their own capacity planning and expectations for Jira's behavior as data grows.
