MongoDB, a robust transactional database, faces limitations when running analytics or aggregations on vast volumes of data. To address this, SingleStore Kai has been introduced as a fast and powerful API to drive up to 100x faster analytics on MongoDB applications without any query changes, application migration, or data transformations. The beauty of SingleStore Kai lies in its simplicity, requiring only an update of the connection string to harness its power with existing MongoDB tools and drivers. A crucial step is setting up a data replication pipeline between MongoDB and SingleStoreDB, which can be fraught with challenges. However, the public preview of native replication for applications built on MongoDB, powered by SingleStore Pipelines, has been introduced, offering advantages such as lightning-fast ingestion, no additional cost, effortless setup, and quick get-started scenarios. This capability allows users to replicate data into SingleStoreDB seamlessly, without incurring extra costs or requiring complex setup. The native replication feature can be achieved through two methods: using MongoDB wrapper commands through the SingleStore Kai endpoint or SQL commands. Monitoring the replication process involves checking the status of the replication using information_schema tables and running specific SQL commands. Overall, SingleStore Kai offers a smooth experience for powering analytics on MongoDB data without any application code changes or data transformations, and now with native MongoDB replication capabilities, setting up data replication from MongoDB into SingleStoreDB is seamless and quick.
