Fivetran has introduced a new method for database replication called Teleport Sync, which allows users to quickly replicate changes using only a read-only user. This technology was acquired from Teleport Data in June 2021 and integrates with Fivetran's existing log-based replication methods. The main advantage of Teleport Sync is that it can be used when traditional log-based methods are not feasible, such as due to hardware constraints or inability to access primary instances or third-party hosted databases. Currently, the technology supports MariaDB, MySQL, Oracle, PostgreSQL, and SQL Server, with plans for further expansion.
