    • Edge objects in Studio now display id, inVLabel, and outVLabel columns in addition to label. Example: see the results of g.E().

    • The maximum length of a value displayed in a Studio cell result has increased from 100 to 150 characters.

  • Fixed a issue in CQL cells where certain table properties were not recognized and reported as a validation error. (STUDIO-3139)

    The following table properties are now recognized as valid:

    • table property additional_write_policy

    • table property read_repair

    • property option incremental of table property nodesync

DataStax Studio 6.8.1 release notes

DataStax Studio 6.8.x release notes are now hosted here: Studio 6.8.4 and later release notes.

19 June 2020

6.8.1 Changes and enhancements

  • Added the last updated date/time to the status line of cell results in Studio. (STUDIO-2298)

  • To use Studio when authentication and authorization are enabled, you must set database permissions on system and system_schema keyspaces and on specific tables. Related settings are needed via GRANT EXECUTE and other commands, depending on the components used. (STUDIO-3046)

  • The Test Connection feature now checks user permissions for the specific keyspaces and tables that Studio queries. (STUDIO-3048)

    When there are problems, the Edit Connection form displays a "Database authorization problem" error message with a details link.

    To learn about the specific issues, click the details link. Example:

    If Studio is unable to connect to Spark SQL, the Spark SQL cells now display a more detailed message to indicate why the problem occurred. Example:

    Studio error message displayed in SparkSQL notebook cell because Always On SQL Server (AOSS) does not have permission to access data
  • Added Studio support for CQL BACKUP commands. See Backup and Restore Service CQL Command Reference. (STUDIO-3076)

  • Added Studio support for the following cqlsh commands:

  • Improved CQL cell validation of maximum length of keyspace and table identifiers to be version specific.

    • Max length is 48 characters in DSE 5.1.x and DSE 6.0.x

    • Max length is 222 characters in DSE 6.7.x and higher

  • Improved the execution time of the first CQL or Spark SQL cell execution. (STUDIO-3126)

  • A Gremlin cell can be executed in Studio when there is no Graph selected for the Notebook. This support enables the execution of Gremlin code that does not require a Graph. (STUDIO-3128)



6.8.1 Resolved issues

  • Duration data type syntax highlighting in CQL cells. (STUDIO-1277)

  • ConcurrentModificationException periodically appeared in standard out. (STUDIO-2216)

  • Null Pointer Exception encountered in Studio when trying to execute a CQL cell that only contained comments. (STUDIO-3117)

  • In Studio 6.8.0, attempts to use an unreserved DSE keyword as the User Defined Type (UDT) name caused an org.apache.cassandra.exceptions.SyntaxException. (STUDIO-3120)

  • In CQL cells, Search query parameters useFieldCache and timeAllowed are now recognized. (STUDIO-3123)

  • Fixed an issue in CQL cells when the selected keyspace value in the Keyspace dropdown was an identifier that must be quoted. (STUDIO-3132)

    Examples of identifiers that must be quoted:

    • starts with a number

    • starts with an underscore

    • CQL reserved keyword

  • Addressed issues with the server startup script on Windows OS when java_home was not defined in the environment. (STUDIO-3136)

March 2020

6.8.0 Changes and enhancements

  • New execution options and connection management options in configuration.yaml. Options from earlier versions that are not present in the file are ignored and can safely be removed. (STUDIO-1696)

    • For CQL and Spark SQL cells, partial statement highlights and execution are supported. It is handy to select any part of the statement to execute the entire statement.

    • For Gremlin cells, you must select the entire statement. Error messages returned indicate the line number within the group of highlighted statements, not the line number of the cell.

  • In the Create Notebook dialog, the connection now auto-fills if there is only a single connection. (STUDIO-2973)

  • Execution configuration changes. (STUDIO-2946)
