Named Dataset Reader

A cube that reads a dataset by name and emits records

Calculation Parameters

  • CPUs (cpu_count) type: integer: The number of CPUs to run this cube with
    Default: 1 , Min: 1, Max: 128
  • Cube Metrics (cube_metrics) type: string: Set of metrics to be collected

    Choices: cpu, disk, memory, network
  • Optional Input Dataset (data_in) type: data_source: The dataset(s) to read records from
  • Input Dataset Name (data_name) type: string: Name of dataset to read
  • Temporary Disk Space (MiB) (disk_space) type: decimal: The minimum amount of disk space in MiB (1048576 B) this cube requires. Due to overhead, request a couple hundred MiB more than required.
    Default: 5120.0 , Min: 128.0, Max: 8589934592
  • Exact Match (exact_match) type: boolean: Only find dataset with an exact match
    Default: False
  • Fast Read (fast_read) type: boolean: Directly sends bytes from the database to the port without constructing an OERecord. This improves read performance, but won’t work within cube groups.
    Default: True
  • Fields To Read (fields_to_read) type: string: Comma-delimited list of field names or IDs to read from the dataset (Leave blank for all).
    Default: “”
  • GPUs (gpu_count) type: integer: The number of GPUs to run this cube with
    Default: 0 , Max: 16
  • Instance Tags (instance_tags) type: string: Only run on machines with matching tags (comma separated)
    Default: “”
  • Instance Type (instance_type) type: string: The type of instance that this cube needs to be run on
  • limit (limit) type: integer: Maximum number of records to read with this cube
  • Enable timing log (log_timer) type: boolean: Log timing of the reader to the log
    Default: False
  • Max Backlog Wait (max_backlog_wait) type: integer: The max time (in seconds) that a cube will be backlogged on a group before being re-evaluated
    Default: 600 , Min: 300
  • Memory (MiB) (memory_mb) type: decimal: The minimum amount of memory in MiBs (1048576 B) this cube requires. Due to overhead, request a couple hundred MiB more than required.
    Default: 1800 , Min: 256.0, Max: 8589934592
  • Metric Period (metric_period) type: decimal: How often to sample metrics, in seconds
    Default: 60
    Choices: 1, 5, 10, 30, 60, 120, 180, 240, 300, Min: 1, Max: 300
  • Thread limit per CPU (pids_per_cpu_limit) type: integer: The number of threads per CPU
    Default: 32
  • Read Dataset (read_dataset) type: boolean: Option to skip dataset reading
    Default: True
  • Shared Memory (MiB) (shared_memory_mb) type: decimal: The amount of shared memory to allow a container to address
    Default: 64
  • Spot policy (spot_policy) type: string: Control cube placement on spot market instances
    Default: Prohibited
    Choices: Allowed, Preferred, NotPreferred, Prohibited, Required
