What is SingleStore?

SingleStore is a scalable SQL database designed for transactional and analytical workloads that demand performance, consistency, and durability. The Single Database for All Data-Intensive Applications can perform as a transactional system and data warehouse in a single integrated architecture for accelerating legacy data architectures or enabling new data intensive applications.

Is everything in Memory?

No. SingleStore utilizes both memory, flash, and spinning disk. SingleStore uniquely accelerates ingest and query performance with memory optimized tables to deliver persistence with full ACID compliance, high availability, and disaster recovery so your data is always accessible.

What is the relationship between SingleStore and MySQL?

SingleStore is a next generation, distributed database built from the ground up for maximum performance for transactions and analytics. The SingleStore server includes its own storage engine and SQL-based execution engine built around scalable distributed execution and lock-free data structures. SingleStore and MySQL servers do not share any code, but SingleStore is compatible with MySQL client software. SingleStore uses the same wire protocol as MySQL and supports similar SQL syntax as MySQL for easier compatibility.

Why is SingleStore based on SQL?

SingleStore was designed to support modern data-intensive applications and real-time analytics while being able to be easily used with existing tools, applications, and skills. SQL is a proven, pervasively used language for writing and retrieving data. It provides rich descriptive capabilities that are interoperable with a large ecosystem of tools, is a straightforward skill to find and learn, and provides the easiest and fastest method to perform analytics.

When is SingleStore a good choice?

SingleStore is a modern NewSQL database that efficiently manages multiple workloads including transactions and analytics in a single integrated relational SQL architecture. SingleStore gives applications maximum performance for real-time decisions and dynamic experiences. Common applications of SingleStore include IoT analytics, fraud detection, streaming media, portfolio analysis, personalization and recommendations, and other data intensive applications. Enterprises choose SingleStore for predictable performance across queries, data ingest, and demanding user concurrency requirements.

How easy is it to install SingleStore?

SingleStore can be installed in minutes on any Linux compliant system. We recommend using pre-defined Cloud Formation templates to quickly deploy on AWS EC2 environments. Customers can also deploy SingleStore in single and multi-node clusters. To see all the available installation options, please read our installation documentation.

What data sources does SingleStore work with?

SingleStore supports several ways to ingest data. See more info here.

  • Batch loading API for one time loads
  • Streaming with exactly-once semantics from Apache Kafka, Amazon S3, Azure Blob, HDFS, and Linux filesystems
  • A high-throughput, bi-directional, parallelized SingleStore Spark Connector

Where can SingleStore be deployed?

SingleStore runs on any commodity hardware system running Linux. It can be deployed on-premises, in any cloud, or as-a-service. This provides complete flexibility for customers to control how they deploy their data analytics infrastructure.

How does SingleStore scale?

SingleStore scales horizontally on cloud instances or industry-standard hardware, providing high throughput across a wide range of platforms. The distributed system automatically shards data among nodes in a cluster. You can add nodes and redistribute shards (also known as partitions) as needed to scale your workload. For high speed ingestion, SingleStore leverages parallel loading to maximize throughput.
