SingleStore Managed Service

How does SingleStore Managed Service differ from the "Self-Managed" version of SingleStore?

SingleStore Managed Service offers the same capabilities, including the ingest and query performance, scalability, and resiliency available in our self-managed software, but without having to worry about installation or cluster administration.

What services are provided in the "Managed-Service"?

SingleStore automatically provisions infrastructure, deploys and configures cluster software, maintains availability, provides scalability, performs backups, and handles software upgrades including SingleStore, operating system, and system software.

How do I know how many units I'll need?

To give you the most accurate information on sizing, contact us to discuss your schemas, queries, and tables together. Request a Quote

Can I use my SingleStore on-premises license in the cloud?

Customers with existing self-managed licenses can not apply licenses or contracts to SingleStore Managed Service. Contact your sales representative for more details.

The region I need isn’t available

We’re currently working on adding more regions, but if you need a specific region please contact us to make it available.

Will I incur any network data transfer charges?

There is no data ingress cost for SingleStore Managed Service but you may incur a charge from your Cloud Service Provider (CSP). For data egress, SingleStore Managed Service includes up to 1TB of data transfer. Anything above that will be charged based on rates set by the cloud provider selected.

What type of support is provided?

All Managed Service customers benefit from Standard Support by default and can opt for higher Support tiers. Our infrastructure is actively monitored 24x7 to guarantee service and cluster availability.

Refer to the SingleStore Support FAQ for more information.

I've explored SingleStore Managed Service in the free trial and now want to POC a larger cluster. How do I do that?

What is the relationship between SingleStore DB and MySQL?

SingleStore DB is a standalone distributed database that is compatible with MySQL client software.

SingleStore DB is not a storage engine or other component of MySQL, nor is MySQL a component of SingleStore DB, and the SingleStore DB and MySQL servers do not share any code. The SingleStore DB server includes its own storage engine and SQL-based execution engine built around scalable distributed execution, lock-free data structures, and machine code generation.

Users use MySQL client software to connect to the SingleStore DB server. SingleStore DB uses the same wire protocol as MySQL and supports similar SQL syntax as MySQL for compatibility with MySQL client software.

Is SingleStore DB vulnerable to MySQL server security issues?

No. The SingleStore DB and MySQL servers are separate database engines which do not share any code, so security issues in the MySQL server are not applicable to SingleStore DB.

SingleStore DB implements the MySQL wire protocol in order to provide compatibility with MySQL client software. A part of this compatibility involves reporting a MySQL version number as described above. As a result of this, numerous third-party security scanners that use the reported version number as a vulnerability marker report false positives, as they’re looking at a version number, not at the actual presence of a vulnerability. Our engineering team as well as a third-party security analysis have confirmed that SingleStore DB is not susceptible to these MySQL vulnerabilities.

Is SingleStore DB a row-based or column-based store?

SingleStore DB provides both in-memory row-based and on-disk column-based stores.

The in-memory row store:

  • Works best for mixed transactional and analytical workloads

  • Provides low latency and highly concurrent reads and writes of individual rows as well as sophisticated analytical SQL queries

  • Supports PRIMARY and UNIQUE keys

  • Supports geospatial indexes

  • Has longer recovery times (as the entire table needs to be loaded into memory)

The on-disk column store:

  • Works best for analytical workloads

  • Allows tables larger than the amount of available RAM in the cluster

  • Uses compression (which lowers disk usage and accelerates replication)

  • Provides fast and efficient scans of large datasets

  • Provides sorted columnstore indexes

  • Is optimized for batch UPDATE and DELETE queries

  • Requires more expensive query compilation (as compared to the row store)

How does SingleStore DB’s in-memory lock-free storage engine work?

SingleStore DB’s storage engine uses multi-version concurrency control with lock-free skip lists and lock-free hash tables which allow highly concurrent reads and writes at very high throughput. Reads in SingleStore DB are never blocked, but updates to the same row can conflict with logical locks.

What is the advantage of SingleStore DB over traditional databases like Oracle, SQL Server or MySQL with data in a ramdisk or large buffer pools?

Two common techniques for leveraging large amounts of memory in traditional databases are storing data files on a ramdisk or running a disk-based storage engine with a large buffer pool. For example, MySQL performs much better with InnoDB configured to use a large buffer pool.

While running an existing storage engine like InnoDB in memory can alleviate some of the bottlenecks involved with disk, SingleStore DB has four distinguishing memory-optimized features that enable it to perform significantly better than disk-based storage engines running in memory:

  • SingleStore DB is a distributed scale-out system. SingleStore DB scales to thousands of machines on commodity hardware.

  • No buffer pool. Traditional databases manage a global buffer pool since they assume that the dataset can’t fit into memory. The buffer pool is a resource shared across all databases and all tables, which creates significant contention.

  • Lock-free data structures. SingleStore DB uses memory-optimized, lock-free skip lists and hash tables as its indexes. Unlike B+ Trees, these data structures are designed from the ground up to be fast in memory.

  • Code generation. Lock-free data structures are so fast that dynamic SQL interpretation quickly becomes the limiting factor for query execution. With code generation, SingleStore DB compiles SQL down to native code for maximum performance.

What is the advantage of SingleStore DB over other distributed databases?
  • Full SQL. SingleStore DB supports full SQL and transactional semantics.

  • Storage pyramid. SingleStore DB combines row and column store engines tuned for memory and flash storage.

  • Scales on commodity hardware. SingleStore DB doesn’t require exotic hardware and can run on premises or in the cloud.

  • Enterprise ready. SingleStore DB supports a large number of enterprise security and manageability features.
