Show HN: Timeplus Proton 3.0 – First vectorized streaming SQL engine Two years after open sourcing Proton, we're releasing v3.0 which brings enterprise-grade streaming capabilities to the open source version: full connectivity, processing, and routing in a single binary with zero dependencies. Key features: First vectorized streaming SQL engine in modern C++ with JIT compilation High-throughput, low-latency, high-cardinality processing End-to-end streaming: ETL, joins, aggregation, alerts, and tasks Native connectors: Kafka, Redpanda, Pulsar, ClickHouse, Splunk, Elastic, MongoDB, S3, Iceberg Native Python UDF/UDAF support to support your AI/ML work loads The same performance we've proven in large enterprise deployments is now available in the community edition. Would love feedback from anyone working with streaming data or looking for Flink/ksqlDB alternatives. https://ift.tt/yfquX65 October 22, 2025 at 07:32AM
