- Amazon Redshift delivers faster performance for BI dashboards and real-time analyticsby Stefan Gromoll on June 29, 2026 at 5:05 pm
Today, we’re excited to announce a new performance optimization in Amazon Redshift that improves the response times of low-latency SQL queries, such as those used in real-time analytics applications or generated by BI dashboards. With this enhancement, you can experience improved query latencies because of a reduction in the time Amazon Redshift spends preparing SQL queries for execution. SQL queries start faster, so they return results quicker.
