Building a Jira Analytics Pipeline with AWS Lambda and Athena (Without Double-Counting Everything)

Jira's built-in reports stop at the board boundary. This guide walks through a Jira analytics pipeline built on AWS Lambda, S3 and Athena, organised around the four failure families that actually bite: the removed search endpoint, silently truncated changelogs, incremental loads that duplicate rows, and an S3 layout that quietly inflates your query bill.

Redshift Cost Optimization for SaaS Analytics: The Levers That Actually Move the Bill

In a SaaS analytics product, the Redshift bill tracks how often queries arrive, not how much data they touch. Here is how the meter actually works, why connection pools bill you while nobody is using the product, how to attribute spend to a tenant, and which isolation choices quietly cost more than they save.
