during setup. An aggregator node is responsible for receiving SQL queries, breaking them up across leaf nodes, and aggregating results back to the client. A leaf node stores SingleStore data and processes queries from the aggregator(s). All communication between aggregators and leaf nodes is done over the network using SQL. SingleStore uses hash partitioning to distribute data uniformly across the number of leaf nodes.
489:(analytics) and data warehousing use cases. As an example, a large clinical data set for data analysis is best stored in columnar format, since queries run against it will typically be ad hoc queries where aggregates are computed over large numbers of similar data items. Data for columnstore tables is stored on-disk, supporting fast sequential reads and compression that typically reaches 5-10x.

SingleStore is also available as a managed service named SingleStore
Managed Service, available in various regions in Google Cloud and Amazon Web Services, with a Microsoft Azure implementation promised for the near future. The underlying engine and potential system performance are identical in all distribution formats.
554:. Blobs that are not queried are automatically deleted from SingleStore node’s local disk, allowing the cluster to hold more data than available disk, making the cluster’s storage “bottomless.” New replicas do not need to download all blob files to come online, creating and moving partitions. Bottomless acts as a “

A SingleStore cluster can be configured in "High
Availability" (HA) mode, where every data partition is automatically created with master and slave versions on two separate leaf nodes. In HA mode, aggregators send transactions to the master partitions, which then send logs to the slave partitions. In

Bottomless storage separates storage and compute for SingleStore. Data files persist to S3 or comparable blob storage and NFS, asynchronously. The “blobs” are the compressed, encoded data structures that back the columnstore. High availability is maintained in the SingleStore cluster for the most

Shortly after launch, MemSQL added general support for an on-disk column-based storage format to work alongside the in-memory rowstore. The decreases in cost of memory slowed over time, and the market for purely in-memory database systems largely failed to materialize, with increasing demand for

SingleStore can be downloaded for free and run on Linux for systems up to 4 leaf nodes of 32 gigs RAM each; an
Enterprise license is required for larger deployments and for official SingleStore support. SingleStore clusters can be managed in containers using the SingleStore Kubernetes Operator.

A SingleStore database is distributed across many commodity machines. Data is stored in partitions on leaf nodes, and users connect to aggregator nodes. A single piece of software is installed for SingleStore aggregator and leaf nodes; administrators designate each machine’s role in the cluster

Durability for the in-memory rowstore is implemented with a write-ahead log and snapshots, similar to checkpoints. With default settings, as soon as a transaction is acknowledged in memory, the database will asynchronously write the transaction to disk as fast as the disk allows.

optimized for fast, lock-free processing in memory. Columnstores store data indexed in sorted segments, in order to maximize on-disk compression and achieve fast ordered scans. SingleStore also supports using hash indexes as secondary indexes to speed up certain queries.
574:
The on-disk columnstore is actually fronted by an in-memory rowstore-like structure, indexed using a skiplist. This structure has the same durability guarantees as the SingleStore rowstore. Apart from that, the columnstore is durable, since its data is stored on disk.

On
October 27, 2020, MemSQL rebranded to SingleStore to reflect a shift in focus away from exclusively in-memory workloads. The new name highlights the goal of achieving a universal storage format capable of supporting both transactional and analytical use cases.
