​
New Features

  • Configure tiered storage directly in Data Portal
    Introduced support for configuring Pinot tiered storage from Data Portal. Users can enable or disable tiered storage, configure tiers following documented best practices, and rely on sensible defaults where appropriate.
  • Broker and server tenant configuration in the UI
    Added the ability to configure broker and server tenants for tables directly from Data Portal, removing the need for manual edits to accomplish cluster-level configuration.
  • Retention time configuration
    Introduced controls to set and adjust table retention time (defaulting to 10 years), giving users direct control over data lifecycle policies without leaving the UI.
  • MAP data type — end-to-end support
    Added full support for the Pinot MAP data type across the stack. The Data Modeling UI lets users define MAP fields with key/value specs, validation rules, and index constraints (JSON index supported; some index types restricted). Query Console renders MAP column values as JSON for easier inspection.

​
Enhancements

  • Saved queries no longer auto-run on click
    Saved queries are no longer executed automatically when clicked. Users can now open a saved query to review or edit it before choosing to run it, reducing accidental execution of heavy queries.
  • Support for newer Kafka consumer implementation
    Updated the default Kafka consumer implementation in Data Portal to use the newer KafkaFactory class from Apache Pinot. This aligns with current best practices and improves compatibility with newer Kafka and Pinot deployments.
  • Long double values no longer show as “Invalid Number”
    Fixed an issue where certain long double values (for example, 97.60000000000001) were incorrectly displayed as “Invalid Number” in query results. These values now render correctly.
  • Stale ingestion status in the Data Portal UI
    The table ingestion status in the Data Portal UI could appear outdated even while ingestion was running successfully. The table details view now refreshes more frequently, giving users an accurate, up-to-date status.
  • Pinot Preview API hanging on S3 files
    Resolved an issue where the Pinot Preview API could hang when previewing data from millions of S3 files. The preview experience for S3-based sources is now more reliable.
  • Clearer permission error for running queries
    Improved error handling in Query Console when a user is missing the getRunningQueries permission. Queries continue to run successfully, and the UI now shows clearer, less disruptive messaging instead of a confusing 403 popup.

​
New Features

  • Protobuf descriptor file support for real-time tables
    When creating real-time tables with Protobuf data, users can now point to a descriptor file (for example, a file on S3) instead of requiring a schema registry URL. This aligns Data Portal with common Protobuf deployment patterns and removes the need for manual overrides.
  • Cancel running queries from the editor
    The query editor now sends a unique client query ID when executing a query and can use that same ID to cancel it mid-flight. This gives users better control over long-running or accidental queries.

​
Enhancements

  • Text index support in index configuration
    Extended index configuration to include text index options via Pinot APIs, improving query performance and search flexibility on free-text fields.

​

​
New Features

  • Query observability and cancellation
    Operators can now see all running queries alongside their metadata and total runtime, and cancel them via Pinot’s query APIs. This fills a key gap for managing long-running or expensive queries.

​
Enhancements

  • Richer Table List view
    The Table List now surfaces operational details at a glance: ingestion status with a clear definition of “healthy”, disabled table indicators, data source details (bucket, topic, or saved connection name), table size, and segment count. Real-time tables that have no scheduled next run show “N/A” rather than a misleading value.
  • Inline IAM setup guidance for S3 and Kinesis
    The S3/Kinesis connection flow now includes sample IAM and trust policies with placeholders for StarTree and bucket details, plus a link to the full IAM role setup guide. Users get step-by-step guidance without leaving Data Portal.
  • Group claims visible in the user menu
    When RBAC is enabled, the user menu now shows the group claims from the authentication token alongside the user’s email. A summary of groups is shown by default with an option to expand all. When RBAC is off or the token carries no group claims, the UI handles this gracefully.
  • Stale error messages cleared on retry
    When a user retries an action after a failure, the previous error toast is now dismissed before the new attempt resolves. This prevents stale errors from lingering and makes the outcome of each retry clear.

​
New Features

  • Visual query execution stats and EXPLAIN PLAN
    Query Console now includes visualizations for execution stats and EXPLAIN plans, giving users a clear picture of how queries run and where time is spent. This makes performance debugging significantly easier without leaving Data Portal.
  • Cleaner execution details with a dedicated JSON tab
    Execution details are now organized into tabs, with raw JSON moved to its own tab and the table widget standardized across the app. Switching between a tabular and JSON view of query metadata is now straightforward and clutter-free.
  • Type-ahead search in all dropdowns
    Every dropdown in Data Portal now supports inline filtering — type a few characters to narrow a long list of options. Loading indicators appear inside the dropdown while data is being fetched, making it clear when results are on the way.

​
Enhancements

  • Transformation rules consistently enforced across views
    Fixed an inconsistency where applying transformation functions to existing fields was blocked in Table View but allowed in JSON View. Validation is now enforced at the API level so invalid transformations are rejected regardless of which view is used.
  • Query execution metadata no longer returns empty values
    Resolved an issue where the Query Console SQL API sometimes returned zero or empty values for query timings and stats. Execution metadata is now populated correctly in both the UI and API responses.

​

​
New Features

  • Stage-level stats for multi-stage engine queries
    Query Console now includes stageStats in the JSON response and a visual representation of the stage stats when running queries with the multi-stage engine. This gives users detailed per-stage execution stats for performance tuning and troubleshooting without needing a separate tool.

​
Enhancements

  • Smarter segment builder defaults based on schema width
    Data Portal now automatically sets columnMajorSegmentBuilderEnabled based on table schema width — disabled for tables with fewer than 40 columns, enabled for wider schemas. Commit-time compaction defaults to off, with the option to enable it when turning on Upsert during table creation. This avoids a one-size-fits-all configuration and improves out-of-the-box performance.
  • Consistent default indexes across all ingestion flows
    The Upload File ingestion flow now applies the same default index configuration logic used in other ingestion paths. Tables created from uploaded files get sensible indexes automatically, reducing the need for manual tuning after setup.
  • JSON and text columns default to no-dictionary
    JSON and text columns are now marked as “no dictionary” by default, with JSON index enabled where appropriate. This prevents the segment bloat that occurred when these column types were incorrectly assigned a dictionary, and aligns default behavior with best practices for JSON and text workloads.

​
December 4, 2025

​
New Features

  • Folder selection for batch sources
    When adding a batch source in Data Portal, you can now browse and select folders directly using a folder picker instead of typing paths manually. This makes source configuration faster and reduces the chance of path errors.
  • Partial results in Query Console
    When some segments are unavailable, Query Console now displays the partial results alongside a clear error message, rather than showing only an error.

​
Enhancements

  • Ingestion type renamed from “Standard” to “Append”
    In the Additional Config section for real-time tables, the ingestion type previously labeled “Standard” is now called “Append”. The new label better describes how the mode works and reduces confusion when choosing between Append, Upsert, and Dedupe.
  • Ingestion failures surface explicitly Ingestion flows now default to "continueOnError": false, so failures are surfaced immediately instead of being silently skipped. This makes it easier to catch and act on ingestion issues early.
  • More reliable file pattern handling
    The ingestion backend now correctly prioritizes includeFilePatterns when present, ensuring ingestion follows the configured patterns and avoids picking up unintended files.

​
November 11, 2025

​
New Features

  • Tableau available as a dedicated client
    Tableau is now listed as a first-class client in the Clients page, with a tailored connection URL generation flow. This removes the need for manual URL construction when connecting Tableau to StarTree.
  • Clients section moved into Data Portal
    Client connection management has moved from MyApps into Data Portal, so all client setup and configuration is accessible from one place within the main UI.
