Azure Data Explorer

  1. Provide meaningful error messages or links to report or resolve errors

    I am using the Web UI to attempt to ingest data from ADLS gen2 storage. The data was created by Azure Cost Management Export. The UI throws the following error :

    Couldn't infer file schema. Error: Invalid length for a Base-64 char array or string.
    Timestamp=2021-07-19T08:17:40.7589123Z
    ServiceAlias=DETCP
    MachineName=KEngine000000
    ProcessName=Kusto.WinSvc.Svc
    ProcessId=5948
    ThreadId=5956
    AppDomainName=Kusto.WinSvc.Svc.exe
    ActivityStack=(Empty activity stack)

    Is this something I can solve ? Is it a Data Explorer Bug ? Is there a link to report this to the appropriate azure team ?

  2. Others can't see my dashboard

    I've created a dashboard and followed all steps mentioned on this page to provide access to my team members (I added the team first, and that didn't work. I added each person individually, which also didn't work.) My teams members still get an "Access denied".

  3. ArgPercentile

    extract the value of a column based on the percentile of another column? Similar to how argmax() retrieves the value of a column in the same row as the max of another column

  7. Support for ingesting RAW data from event hub into ADX

    Currently this is supported for other ingestion sources, but not event hub.
    Using TEXT instead would split messages based on newline which will not work for our use-case since newlines are expected in the body of text for a single message

  8. Disable refresh button in ADX Dashboards till refresh is finalized

    Dashboard refresh button should be disabled till refresh is fully executed.

  9. Support any(*) aggregator without prefixing all columns with "any_"

    Hey,

    We happen to use "summarize any(*)" frequently, and have to rename our columns back to their original name (without the 'any_' prefix) -- and this is a bit annoying.

    I imagine where this prefix came from, which is to emphasize to the user that the value held by this column is not deterministic/consistent across different query executions, however it makes the lives of those who understand this aggregator more difficult than it should be.

    Appreciate if there could be a 'set' command instructing 'any(*)' to not prefix the columns.

    Thanks!

  10. Dynamic Hierarchical Custom Quotas

    Consider the following Scenario:
    A Service which allows customers to provision Capacities (you can think of Capacities like managed VMs)—the Customer would like an interface to the usage metrics of the Capacity (so they know why their Capacity was overloaded and non-performant, for example). The Service stores Capacity usage metrics in a Kusto Database and provides an in-Service view of a customer’s Capacity usage metrics. When the Customer invokes the in-Service usage metrics interface, a query to the underlying Kusto Database is issued and the returned data is visualized.

    In this Scenario, user action causes Kusto Database traffic and we…

  11. Allow prev() to return previously generated value (window function)

    It would be very useful to be able to access the previously generated value of the generated column from within the window function. Prev(column) currently only lets you select existing columns and the previously generated value doesn't seem to be accessible until after the window function completes which means doing things such as running min/max isn't possible.

  12. pack_all function should have ability to specify subset of columns instead of all

    packall() works on ALL the columns in input table , instead of that we should have an ability to specify columns , either individually such as packall(col1,col2,col3) or through regex, wild card etc such as packall(col*). Also, another function we have as of now pack() does not do that , it accepts key value pairs such as pack(key1,value1,kay2,value2,...). The suggested feature will be useful in case where we need to have multiple json bags out of different sets of columns from input table. e.g. extend prop1=packall(col1,col2,col3) , prop2 = packall(col4,col5,col6). This can be introduced as

  15. Free tier on the dev/test cluster

    It would be great to have an option to turn off the cluster when the cluster did not receive any data or requests for some time.

    Or have a free tier option to test out the product.

  16. Add hash_sha1() method

    It seems the hashsha1() method is missing.
    There are hash
    sha265() and hashmd5() methods. Is it on purpose the hashsha1() doesn't exist?
    It would be great to have hash_sha1() method available so I won't need to work it around .

  19. Azure Data Explorer Dashboard - Single Selection query-based parameter defaultValue

    In Single-Selection query-based parameter, we can only select the output or selectAll as the defaultValue

    "defaultValue": { "selectAll": "explicit" },

    It would be great, if we can expend the default value to be able to have None. Similar to how we do free text

    defaultValue": {"selectAll": "none",}

  20. Set request rate limit on the global cluster level

    Currently a request rate limit can only be set on a workload group level. So that if there are two workloads with 100 request rate limit each, there could be 200 concurrent request executed at any given moment.

    Setting the global rate limit would allow us guarantee that there will not be any moment in time when more than 100 requests are execute from all the workloads combined.
