        compute resources. Workspaces can be suspended (paused) to save costs
        and resumed when needed.
      aliases:
        - Database Instance
        - Cluster

    - term: Workspace Group
      definition: >-
        A logical container that groups related workspaces and provides a shared
        administrator password, network firewall, and regional deployment.
      aliases:
        - Cluster Group

    - term: Helios
      definition: >-
        SingleStore's fully managed cloud database service, providing elastic
        scaling, automatic backups, and infrastructure management.

    - term: Data API
      definition: >-
        The SingleStore HTTP API for executing SQL statements without requiring
        native database drivers. Uses /api/v2/exec for DML/DDL and
        /api/v2/query/rows or /api/v2/query/tuples for SELECT results.

    - term: Aggregator
      definition: >-
        A SingleStore node type that receives queries and distributes work
        across leaf nodes. The Data API connects to aggregators.

    - term: Leaf Node
      definition: >-
        A SingleStore node that stores data partitions and executes distributed
        query fragments directed by aggregator nodes.

    - term: Columnstore
      definition: >-
        SingleStore's columnar storage format optimized for analytical queries.
        Data is stored in compressed column segments for fast aggregation.
      aliases:
        - Column Store

    - term: Rowstore
      definition: >-
        SingleStore's row-based in-memory storage format optimized for
        transactional queries with low latency point lookups and updates.
      aliases:
        - Row Store
        - In-Memory Store

    - term: Universal Storage
      definition: >-
        SingleStore's hybrid storage combining rowstore (hot data) and
        columnstore (warm/cold data) in a single table for mixed workloads.

    - term: Workspace Size
      definition: >-
        A compute tier designation (S-00, S-1, S-2, etc.) that determines the
        CPU, memory, and performance characteristics of a workspace.
      aliases:
        - Compute Size
        - Instance Size

    - term: Auto-Suspend
      definition: >-
        A feature that automatically suspends a workspace after a configurable
        period of inactivity to reduce cloud spending.

    - term: Stage
      definition: >-
        SingleStore's distributed file storage system for storing notebooks,
        models, and data files. Accessible via the Management API Files endpoints.

        - Helios Stage
        - Spaces

    - term: Job

        SingleStore workspaces can be deployed.

    - term: Management API
      definition: >-
        The SingleStore REST API for infrastructure automation - creating,
        configuring, and terminating workspaces, workspace groups, jobs, and
        managing organization settings.

    - term: Mixed Workload
      definition: >-
        A database usage pattern combining both transactional (OLTP) and
        analytical (OLAP) queries, which SingleStore is designed to handle
        simultaneously without separate systems.
      aliases:
        - HTAP
        - Hybrid Transactional Analytical Processing
