 Automatic index compaction helps you reduce the consumption of storage space, disk I/O, CPU, memory, and improve workload performance without investing time and effort into index maintenance jobs. Index compaction is performed continuously and with low overhead as the data in the database changes.

-> Automatic index compaction is currently in preview in Azure SQL Database, Azure SQL Managed Instance with the always-up-to-date [update policy](/azure/azure-sql/managed-instance/update-policy), and SQL database in Fabric.
