Recent enhancements to the New Relic Query Language (NRQL) now allow for more powerful data exploration within the New Relic Database (NRDB), making it easier for users to handle telemetry data efficiently. The introduction of wildcards simplifies the process of querying and charting multiple metrics, eliminating the need to manually update dashboards and queries when new metrics are added. Additionally, NRQL now accurately distinguishes between null values, empty strings, and empty sets, ensuring more reliable query results. This update allows users to better utilize "tags" in their data and correctly returns 'NaN' for the minimum, maximum, or average of empty sets, rather than '0', thus providing more accurate insights from the data. These improvements aim to enhance data analysis and decision-making processes for New Relic users.
