SingleStore Helios

Overview

SingleStore Helios is a cloud database service that runs transactional and analytical workloads alongside varied data models and AI compute. It is best suited to teams building on AWS, Google Cloud, or Azure that want one managed service for those needs. Its breadth is a strength, but Shared is for non-production use and self-support, so production teams should look at paid plans.

Key features

Helios handles relational data as well as JSON/BSON documents, vector search, full-text search, time-series, geospatial, and key-value workloads. That range may let teams consolidate workloads that otherwise call for several database types; for teams with a narrow relational use case, it may be more platform than they need.

Transactional and analytical workloads share one database, and storage can scale independently of compute. This is a useful fit when those workloads have different capacity needs, though it does not by itself establish a performance or cost advantage.

SingleStore Pipelines ingests data from Kafka, Amazon S3, and HDFS. Jupyter notebooks, data integration services, and an AI compute service extend the offering beyond database operations. Integrations include Datadog, Terraform, Apache Spark, AWS Glue, Azure Data Factory, dbt, and Fivetran, which can suit teams already using that ecosystem.

Helios runs on AWS, Google Cloud, and Microsoft Azure. SingleStore describes security across application and cloud security, corporate IT security, and governance, risk, and compliance. Production deployments across AWS, Azure, and Google Cloud Platform maintain up to a 99.99% uptime SLA; the actual plan terms distinguish availability-zone configurations.

Pricing

Shared is free and includes one free workspace for evaluation, development, and non-production testing. It is self-support, making it a reasonable place to explore Helios but not a production option.

Standard costs 0.99 USD per month, billed monthly. It targets managed production workloads and includes read replicas, database branching, 30-day monitoring, Standard Support, and a 99.9% SLA in one availability zone or 99.99% across two. This is the relevant starting plan for general-purpose production use.

Enterprise costs 1.49 USD per month, billed monthly. It adds online point-in-time recovery, Smart Disaster Recovery, audit logging, and customer-managed encryption keys, with the same listed SLA choices as Standard. Teams needing those recovery and governance controls have a concrete reason to move up; otherwise Standard already covers the stated general-purpose production features. Backup retention is 7 days.

Platforms

Helios is available through web and API, and runs on AWS, Google Cloud, and Microsoft Azure. Those options make it relevant to teams choosing among the three major cloud providers; the platform facts do not extend to self-hosted deployment.

Who it's for

Choose Helios when a team wants transactional and analytical work in one cloud database, needs several data models or ingestion paths, or expects to use its notebooks and AI compute service. It is less compelling for teams seeking only a single-purpose database or a free production workspace, since Shared is explicitly non-production and self-support.

Pros and cons

• Pro: A broad set of relational, document, search, time-series, geospatial, and key-value capabilities can support varied workloads in one service.
• Pro: Independent storage and compute scaling, plus ingestion from Kafka, S3, and HDFS, gives teams flexibility in shaping data flows and capacity.
• Pro: Standard and Enterprise offer production plans with stated availability SLAs, and Enterprise adds recovery, audit, and encryption controls.
• Con: Shared is limited to evaluation, development, and non-production testing, and provides self-support.
• Con: Teams that do not need the breadth of workloads, models, and AI tools may have little reason to choose a wider platform over a narrower database.

Alternatives

VoltDB offers a free Developer Edition for individual developers and early exploration, with local or cloud use and sample apps, tutorials, and docs. Aerospike Database has a free Community Edition with limits of 8 nodes, 2.5 TB of data, and 2 namespaces.

Apache Geode is a free option available as binary and source distributions under the Apache License. RonDB offers a free serverless option via Hopsworks with quotas on feature groups and memory. Apache Ignite is a free downloadable option with binary, source, Docker, and Maven/Gradle choices. Infinispan provides a free Community Edition as an embedded library or standalone server. Valkey is a free open-source BSD datastore for self-hosting.

Verdict

SingleStore Helios is a strong choice for cloud teams that need one service for transactional and analytical workloads, diverse data models, ingestion, and AI compute. Its production plans add meaningful support and reliability terms, with Enterprise recovery and security controls for teams that need them. Look elsewhere if you only need a narrow database or require a free production tier.
