Basic configuration options in DataStax Studio

dse.yaml

The location of the dse.yaml file depends on the type of installation:

Package installations Installer-Services installations	/etc/dse/dse.yaml
Tarball installations Installer-No Services installations	`installation_location`/resources/dse/conf/dse.yaml

The primary configuration file for Studio is dse-studio-install-dir/configuration.yaml.

A sample configuration file in XML format:

# Maximum number of items returned per cell execution. Additional items will be truncated.
# Unit: count / number of items
resultSizeLimit: 1000

# Maximum size of a cell result. If a cell result exceeds this size then the cell execution will fail.
# Unit: bytes
maxResultSizeBytes: 524288

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

# TraversalSource mapping for real-time and analytic execution engines. These values correspond to the traversal sources
# configured in dse.yaml.
# Unit: string
traversalSources:
  realTimeTraversalSource: g
  analyticTraversalSource: a

# This refers to the datastax-studio server
server:
 httpPort: 9091
 # WARNING!!! Changing this setting from the default(localhost) could pose a security risk as other users on external machines could then
 # gain access to notebooks and the clusters those are connected to.
 # Studio is designed to be used as a desktop application, but if deploying centrally you should be aware of the potential security risks.
 # Please visit http://docs.datastax.com/en/latest-studio/studio/reference/configuration.html for information on configuration
 httpBindAddress: localhost

logging:
 fileName: studio.log
 maxLogFileSize: 250 MB
 maxFiles: 10
 directory: ./logs

# User data, where we store data specific to a user
# in the application.  For the short-term this is the file system, which
# is why we need to explicitly configure a location
userData:
  # defaults to a .datastax_studio folder in your home directory, such as  ~/.datastax_studio
  # set to a non-null value to override
  baseDirectory: null

Cell options

resultSizeLimit: Maximum number of items returned per cell execution. Additional items will be truncated. Default: 1000.
maxResultSizeBytes: Maximum size of a cell result. If a cell result exceeds this size then the cell execution will fail. Default: 10485760.
executionTimeoutMs: Cell execution timeout in milliseconds. A value of 0 indicates no timeout override. Uses the DSE server timeouts configured in the dse.yaml file. Default: 0.

traversalSources

Traversal source mapping for real-time and analytic execution engines. These values correspond to the traversal sources configured in the dse.yaml file.

realTimeTraversalSource: Traversal source mapping for real-time execution engine. Default: g
analyticTraversalSource: Traversal source mapping for analytic execution engine. Default: a.

Server

httpPort: The port on which the Studio server is running. Default: 9091
httpBindAddress: The IP address to which the Studio server is bound. Default: 127.0.0.1.

Note: In Studio version 1.0.0, if you change either of these options, you must also change the corresponding ide options, graphSchemaServiceURL and graphSchemaServicePort.

Logging

Logging-related options:

fileName: Name of the log file. Default: studio.log.
maxLogFileSize: Default: 250 MB.
maxFiles: Maximum number of log files. Default: 10.
directory: Path of the directory in which log files are stored. Default: ./log.

User data

Directories where user data is stored relative to the baseDirectory:

baseDirectory: Default: ~/.datastax_studio
connectionsDirectory: userdata/connections
