There are no good ways to remove data from TSI, especially during development its a pain to recreate TSI's because you can't go back and change data and if you rerun the datasets you get duplicate datapoints, at the very least an update feature should be present that is based on the event time.

Downloading events from TSI is currently limited to 10000 events. This is probably because the query API is limited to 10000 events per query. Please consider increasing this limit.

Add support for Azure CLI to create and manage Azure Time Series insights.

There are some Japanese customers interested in TSI. In order to take it into their models, I would like to describe a story or a path that is going to be available in Japan after the end of preview period.

Add support for UNIX timestamp from device as timestamp field (actually only ISO format is supported)

I would like to be able to embed the Analyze page into an existing website, passing parameters such as list of devices, environments, starting time period. Also options to turn on/off page widgets (like Save Query).

In the GA version grouping is supported using the "split by" feature, or actually by not using it. Doing aggregates using grouping is my major use case and I guess that others need it too.

The preview version has a more appealing price model, and I would prefer to work the preview version than sticking to a "doomed" version since we are in early stages of the project.

Suggestion: Add a way to do grouping in preview version

As of now current documentation looks quite isolated. It would be better to have a doc starting from posting json

{

    "deviceId": "FYYY",

    "timestamp": "2018-01-17T01:18:00Z",

    "series": [

        {

            "tagId": "pumpRate",

            "value": 0.58015072345733643

        },

        {

            "tagId": "oilPressure",

            "value": 22.2

        }

    ]

}

to how to model this json for better visualization. to a new comer modeling and hierarchy concepts are kind of still isolated. It might just be the missing piece.

The timestamp is an important factor in the Azure Time Series Insights. But there is no proper documentation regarding the format, the best practices to send timestamp in UTC (or in any other format) from the IoT device. It will be extremely helpful if there is proper documentation for this scenario.

For C# users, a NuGet package should be made available for working with the TSI Query API.

There is some code already here: https://github.com/Azure-Samples/Azure-Time-Series-Insights/tree/master/csharp-tsi-preview-sample/DataPlaneClient/Generated
