Streamlining UI and UX on Operations and Visual Query Builder. Plus a new Data Masking technique, and much more in the latest release of Studio 3T.

Headline features

Data Masking | Shuffle, a new Data Masking technique

This year, we’ve been working hard to improve Data Masking to meet your compliance and security needs. To that end, we’ve added a new Data Masking technique: Shuffle.

Studio 3T Data Masking Shuffle

Each document within the shuffled field will receive a new value from a different document, while the total set of values across the collection will remain the same. This way, for example, developers in a testing environment can work with a realistic set of data that is nonetheless obfuscated. Shuffle can be used on all supported field types.

Learn more about Shuffle and other Data Masking techniques in our Data Masking documentation.

Visual Query Builder | Now supporting two-way interaction between the Query Bar and Visual Query Builder

At Studio 3T, we care about a streamlined user experience. This is certainly what we had in mind when we implemented the Visual Query Builder, and we haven’t stopped making progress.

Now, when writing a query, adding a projection, limit, sort or skip in the query bar, those operations will appear real-time in the Visual Query Builder. Similarly, any method used in the VQB will be reflected in the query bar.

Studio 3T VQB + Query Bar Interaction

Operations | Expand the Operations pane into a new tab

Need a larger overview of your operations? We’ve made it possible to expand the operations pane into its own tab. Simply click the icon in the pane right of the eraser. Closing the tab will move the pane back to its default corner position. You can also drag the Operations tab out to open it in a pop-out window.

Maintenance Updates

MongoDB 4.4 | Now bundling MongoDB 4.4 tools

Studio 3T now also bundles mongo shell, mongodump & mongorestore from MongoDB 4.4.

Please note that the version and executable of the mongo shell is now configured separately in the new IntelliShell tab.

You can choose to use these tools and update your configuration in these locations in-app:

  • Studio 3T Menu > Preferences > MongoDB Tools / IntelliShell tab
  • Open Connection Manager > Edit a connection > Click on the MongoDB Tools / IntelliShell tab

User Shoutouts

We'd like to thank the many users of Studio 3T for reaching out for their own needs: Abdelrahman Hafez for requesting the two-way interaction feature between the Query Bar and Visual Query Builder; Tim Sullivan for suggesting the option to show the command line of mongodump and mongorestore executions in the Export Wizard; Erik Schannen for reporting an error when using simplified form in the $merge stage; Rutger Bevers for reporting an unnecessary error when updating a JSON document after not making any changes; and to everyone else who made this release possible.
