DataStax Studio configuration file (configuration.yaml)

# Maximum number of items returned per cell execution. Result set will be
# truncated to this number of rows, edges, vertices, etc.
# Default: 1000 items
resultSizeLimit: 1000

# Graph: maximum content length returned for a cell result (bytes).
# Default: 524288 bytes
maxResultSizeBytes: 524288

# Cell execution timeout (milliseconds). A value of 0 indicates no timeout and
# will depend on the DSE server timeouts configured in dse.yaml.
# Default: 0 milliseconds (no timeout)
executionTimeoutMs: 0

# Determines if selected editor text can be executed, instead of the entire
# cell content. When set to 'true':
# Graph cells: only the exact selected text is executed
# CQL and Spark SQL cells: the selected text is expanded to full statement(s)
# before being executed.
# Default: true
executeSelectionEnabled: true

# Studio web server options.
server:
  # Studio web server http port
  # Default: 9091
  httpPort: 9091

  # WARNING: Changing the setting from the default (localhost) can pose a
  # security risk as users on external machines can gain access to notebooks
  # and the DSE clusters those notebooks are connected to.
  # Studio is designed to be used as a desktop application. Distributed
  # deployment introduces potential security risks.
  # See: https://docs.datastax.com/en/allStudioConfig/
  # for additional configuration information.
  # Default: localhost

  # Spark SQL log level.
  # 0: Disable all logging
  # 1: Log severe error events that abort the driver

  # A value of 'null' will translate to ~/.datastax_studio
  # Default: null
  baseDirectory: null

  # Save frequency for minor cell revisions (seconds). Changes considered 'minor'
  # include: cell editor and settings changes. Major changes, such as cell
  # execution and new results always create a new revision immediately.
  # Default: 300 seconds
  historySaveFrequencyInSeconds: 300

  # Determines if notebook revisions should be deleted based on age.
  # When there are more than 'minHistoryRevisionsToKeep' history revisions,

  # Minimum number of revisions to retain before pruning by date is enforced.
  # Default: 25
  minHistoryRevisionsToKeep: 25

  # Maximum amount of time notebook revision history files are kept before
