Apache Samza vs Timeplus

Apache Samza is a free, open-source distributed framework for applications that process data from multiple sources in real time. It supports stateless and stateful workloads, using a scalable, fault-tolerant state store for retained application state. Developers can use the high-level Streams API, lower-level Task API, Samza SQL or an Apache Beam API; Beam support for Python and Go is described as work in progress. Java and Scala applications can embed Samza as a lightweight client library. Built-in integrations include Apache Kafka, AWS Kinesis, Azure Event Hubs, Elasticsearch and Apache Hadoop, with custom sources also supported. Samza runs on YARN, Kubernetes or as a standalone library across public-cloud, containerized and bare-metal environments. Host affinity and incremental checkpointing help recover tasks and their state after failures. Processing is at least once. The project supports SQL processing and event-time windows, and its documentation describes applications with several terabytes of state and thousands of cores. Samza is self-hosted on Linux and distributed as source artifacts and through Maven; there is no binary release at this time.

Timeplus is a vectorized streaming SQL platform for real-time data pipelines in analytics, telemetry and AI/ML. Its unified engine processes streaming and historical data, using an internal write-ahead log and historical store. Streaming SQL supports streams, views, incremental materialized views, joins, aggregations, enrichment and downsampling. SQL criteria can route data to different sinks, while the console displays lineage for derived streams. Teams can build push-based, low-latency dashboards and set SQL alerts for services such as PagerDuty and Slack. Native connections include Apache Kafka, Apache Pulsar, Redpanda, ClickHouse, Splunk, Elastic, MongoDB, S3 and Apache Iceberg. Other access includes Redpanda Connect, Java, Go and Python SDKs, JDBC/ODBC, WebSockets and REST APIs. Enterprise deployments can run at the edge, in the cloud, BYOC or hybrid environments, on bare metal or Kubernetes. Proton, the open-source core, is available under Apache 2.0. Proton is free; Cloud is $199 a month and has a 14-day trial. Enterprise support is listed within one business day for Cloud and four hours for self-hosted or BYOC.
