      Installing Algorithms

      Algorithms for HDC projections and distributed projections are managed differently.

      HDC Algorithms

      HDC algorithms come as hot-pluggable plugins, allowing installation, updates, or removals without server disruption. Each package includes a .so file and a .yml configuration file, requiring independent installations on each HDC server.

      Installation Methods

      You can install HDC algorithms in different ways:

      • Ultipa Manager: If using this GDBMS of Ultipa, install algorithms directly through the HDC module interface.
      • SDKs: For programmatic access, see the specific algorithm management section for your preferred language SDK:

      Showing Installed HDC Algorithms

      To view the algorithms installed on an HDC server like hdc-server-1:

      show().hdc("hdc-server-1")
      

      The returns include the _algoList_from_<hdcName> table, which lists all algorithms installed on the specified HDC server. It includes the following fields:

      Field
      Description
      name Name of the algorithm.
      type Type of the algorithm, which can be algo or specific system algorithms like pathfind and khop. System algorithms come pre-installed on the HDC server, enabling essential graph queries and other functions.
      write_support_type Supported writeback execution modes.
      can_rollback Indicates true for algorithms with updates that allow rollback.
      params Includes parameters, write_to_file_parameters and write_to_db_parameters.

      Distributed Algorithms

      Distributed algorithms in Ultipa Powerhouse (v5) come pre-installed as part of the deployment package, so no additional installation is needed. These algorithms are readily available for use without further setup.
