We will update the beta version from time to time and list key enhancements in this page.

(in year 2022)

Biweekly Update 9/19-9/30

  • Streaming engine

    • Enhanced dedup function to only cache the unique keys for a given time period. This is useful to suppress the same alerts in the short time period.
    • Support sub-stream, e.g. select cid,speed_kmh, lag(speed_kmh) OVER (PARTITION BY cid) as last_spd from car_live_data
  • Source, sink, API and SDK

    • Updated Python SDK to auto-delete the query history, refine error handling, Please note there is a breaking change, Env().tenant(id) is changed to Env().workspace(id) to be align with our terminology
    • Updated the REST API to show the optional description for source/sink, and replace "tenant" with "workspace-id" in the documentation.
    • The Kafka sink no longer auto-create the topics
  • UI improvements

    • Show the total data size on the home page, as well as the average data in and data out throughput.
    • Added a new 'SQL Templates' button in the query page to help you quickly add common snippets, such as settings seek_to='-1h'
    • Added a closable page description, as well as context aware help side panel.
    • Refined "Data Lineage" page to show stream schema, view SQL, and sink types.
    • Able to set units when you choose to view the latest data.

    • Redesigned home page to show high level information for the workspace.
    • Introduced a new 'Data Lineage' page to visualize the relationship between sources/streams/views/sinks.
    • Enhanced the workflow for visualizing the query result. You need to choose whether to view the latest data, check data trend, or view detailed data.
    • Now you can visualize the query results from a historical query, e.g. select .. from table(..).., and add the charts to dashboards.
    • Removed the browser side data aggregation to improve performance. If the rate of the data is greater than the render interval (200ms), only the last data point within the interval will be rendered. If you run a streaming tail or filter, you no longer can visualize the data with a bar chart. Please use GROUP BY in the SQL for such analysis.
