Couchbase's Capella, a fully managed Database-as-a-Service (DBaaS) available on AWS and GCP, offers users an efficient NoSQL database solution with SQL querying capabilities. Transitioning from legacy relational databases to Capella can be complex, a challenge addressed by MOLO17's GlueSync platform, which facilitates data migration and synchronization between systems. GlueSync supports various data replication strategies, including one-time snapshots and continuous change data capture (CDC), ensuring real-time synchronization between relational databases and Couchbase. With its containerized architecture, GlueSync simplifies setup and configuration, while enhancing data availability, performance, and analytics by leveraging native Couchbase technologies. The platform also reduces the risks associated with data replication and lowers the total cost of ownership for companies adopting Capella, offering a reliable and scalable solution for modernizing data infrastructures.
