Grafana Loki 2.6 introduces significant features such as cross-tenant query federation and targeted log line deletion, enhancing its capabilities for multi-tenant data management and privacy compliance. The cross-tenant query federation enables users to query multiple tenants at once, consolidating results into a single output, which simplifies workflows and reduces operational overhead by allowing data access without physically separating databases for different teams or business units. This feature is particularly useful for administrators requiring a global view of logs across tenants. Additionally, targeted log line deletion addresses the need for precise removal of sensitive information, such as personally identifiable information (PII) or data requested for deletion under regulations like GDPR. Previously, deleting logs involved less precise methods, but now users can utilize LogQL queries to specifically identify and remove unwanted log lines, with immediate frontend filtering making the deletion appear instantaneous. In Grafana Enterprise Logs (GEL), these features are integrated with access control measures to ensure security and proper permissions for executing cross-tenant queries and deletions. These updates represent a significant step forward in data management efficiency and compliance within Grafana Loki's infrastructure.
