RisingWave
RisingWave is a distributed SQL platform for ingesting, transforming, and serving real-time data. Its SQL interface is wire-compatible with PostgreSQL, so PostgreSQL clients, drivers, and tools can connect. New events incrementally refresh materialized views. Barrier-based checkpointing and consistent snapshots support exactly-once processing, while data is persisted in S3-compatible object storage and connector offsets are checkpointed for delivery durability. RisingWave lists 31+ native connectors, including Kafka, PostgreSQL, MySQL, Iceberg, Snowflake, BigQuery, S3, Redis, and Elasticsearch. Self-managed deployments are Apache 2.0 open source, with Docker, Kubernetes, cloud VM, and on-premises options. The hosted Basic plan is $0.23 a month, pay-as-you-go, limited to 64 cores and available in select regions; a free plan and 7-day trial are also listed. Basic includes standard support. Premium 24x7 support can be purchased with Pro, while self-managed deployments offer premium support with an SLA and quarterly success reviews. Listed platforms include API, Linux, macOS, self-hosted, and web.
