  1. Provide out of the box resource governance for Kusto clusters

    Our Kusto cluster is used for production site and tools and needs to have 99.99% availability. However, as our cluster is open to tens of thousands of users across the company for ad-hoc queries, we often suffer from unexpected cluster wide outages due to misbehaved customers. We have tried both cluster-wide query limits as well as customized approaches, however, neither is helping us much. We would like to see Kusto to provide the resource governance solution out of box.

  2. Azure Data Explorer setting to display datetime values in local timezone

    Can Azure Data Explorer support displaying datetime values in local timezone with a setting?
    I'm a bit tired of extending all queries by doing time arithmetic myself (e.g. | extend localT = timestamp - 8h) which is not daylight saving proof as well :)

  3. Push rows to EventHub

    Enable pushing rows to EventHubs.
    * individual or batched messages

    Example (alerting):
    * IoT data being consumed by ADX
    * An update policy is in place that checks the incoming
    * If the check fails then a notification should be sent to an EventHub
    -> picked up from there by other components

  4. Export data from one ADX cluster to a second ADX Cluster

    Add ADX as a destination for the .export capability to be able to move data from one cluster to another. This should work both for one time export and for continuous export.

  5. Provide read access only role to dashboards.

    We are using more and more ADX dashboards at different sauces and some of the internal consumers of these dashboards are not technical or does not have the context/knowledge to query the data. At the moment we are duplicating our dashboards in PowerBi which adds additional works. It would be awesome to have a role that gives only read access to the dashboards.

  7. Create clone of a Kusto Database.

    I would like to have the capability of creating a clone of the database, where the newly created database is exactly the same as one it is cloned from (including permissions, folder structures of tables/functions, etc).

  8. Add ADX as Trusted Microsoft service on firewall

    Please consider to add ADX as a trusted Microsoft service on Azure Event Hubs' (or any other data source service's) firewall or publish IP address range of ingest service.
    For now, we have to deploy the cluster with VNet in order to restrict access of Event Hubs but it seems unnecessary since the traffic between Azure service is completed inside Azure network.
    This option makes it simple/easier for the users to create secure environment.

  9. Include more node memory details for E_LOW_MEMORY_CONDITION errors.

    When a query or command fails with one of the ELOWMEMORY_CONDITION errors, please include information about the node's memory consumption at that point in time. How much was allocated to the current query, to other queries and commands, and how much was remaining available. I think it could help with the diagnostics of such errors.

  10. Translate IP addresses to geo coordinates


    • Given an IP-Address

    • There should be a native KQL function to translate the IP address to a coordinate

    • This will enable the user to enrich telemetry from server/app logs with the corresponding location

  12. Support for features related to GDPR requirements

    As of today we'd have to develop custom solution over ADX in order to support some of the GDPR requirements (list below). It'd be nice to have following features as native capabilities in ADX.


    1. Data classification - possibility to mark a table or column in a table as GDPR relevant data that way query / ingestion logs can be filtered based on the data category


    2. Stream audit logs (read / append / management) for GDPR relevant tables. These logs can be streamed into Storage Account or Log Analytics similar to the Diagnostic Logs setting


    3. Capture the source of ingestion for…

  13. External tables column mapping gets mixed-up when the underlying file column structure is updated for some files

    When using external tables to map files on a storage account, if one has many files already mapped to an external table, and the file structure changes for new files provided to the same storage account location, such as a new column is added to the new files, then the external table mapping get mixed up. We drop the external table and recreated it, adding the new column (which is not added to the end of the new file structure). When querying the external table, ADX provides the new file data in the correct columns, but shows the previous file…

  14. Make http_request and http_request_post plugins work and supported.

    Calling to external resource to download data through HTTP(S) protocols is an awsome idea, unfortunately the plugins do not work correctly and are not supported yet. Consider to speed up the work on it, please.

  15. Provide support to render timepivot / timeline view

    The Timepivot visualization is one of the best visualizations we have come across when analyzing data across hundreds of different tables. It tells the story of “what happened” in a beautiful manner.

    It helps us generates multiple different views of the “same data” by allowing us to pick multiple levels of slicing options views (in this case I have 10 slice options, so for two levels I can get about 90 different views). In addition, clicking on the cells shows the actual activity in detail.

    Given that Kusto is time-optimized and practically every log has timestamps associated with them, we…

  16. Scheduled Jobs

    We are utilizing ADX to stream data from event hubs. This is awesome because we can get a large amount of data with very little work.

    The challenge, is that we sometimes want to "aggregate" multiple (like 100s-1000s) events into summary style tables. We could use ASA or other tools, but it would be really nice to have the ability to schedule jobs in ADX. That way we can keep all of the work close to the data (rather than extract it out and then put it back in)

  17. Allow mapping from Properties, SystemProperties collections on Event Hub data ingestion

    For data ingestion connections which point to Event Hub sources, allow the mapping definitions to access the Properties and SystemProperties collections on the underlying EventData object. Presently, only the Body property is accessible - it is define as the root/$ of the path in mappings.

  18. WithAadUserPromptAuthentication method not available in .NetStandard library

    In Kusto.data Nuget for .NET framework WithAadUserPromptAuthentication method is available in KustoCOnnectionStringBuilder class.

    However this is missing from .NetStandard Nuget library.

    Can this be added?

    Eg:

    KustoConnectionStringBuilder($"https://{serviceName}.kusto.windows.net") .WithAadUserPromptAuthentication(authority);

  19. Allow cluster() to take function/variable values

    When referencing different clusters - espcially w/ the advent of Dashboards and Parameters - it's cumbersome to require each cluster reference to use a string literal. These could be better handled and a better experience delivered by allowing the input to cluster() to take a function or variable value instead of having to be a literal.

    This request comes from https://github.com/MicrosoftDocs/dataexplorer-docs/issues/359

  20. Enable AllDatabasesAdmin role to create volatile databases

    After the database creator role went away, we no longer have a supported way to create volatile databases. E.g. running this command is not supported under the existing set of roles: '.create database TestDB volatile'. Please enable a different role, saw the AllDatabasesAdmin role, to run this type of control command and be able to create volatile databases.
