Hi,
as a vendor, we have to migrate a huge dataset from our app from Jira DC into the cloud. I noticed that my approach is too slow and memory consuming. I require a data pipeline, that reads values from custom fields in Jira issues and pumps that data into the migration platform. Is there any example how to effectively do this with least runtime and memory consume?
I came up to build a CSV and stream through the issues, but I cannot come up with a way in Java to stream the issues directly into the output stream. I only know apache beam, but is there already an existing solution in Java or Jira DC?
