Week in Review -- August 28, 2017

New Features

  • List of deprecated components in the Project Overview:

    In the Project Overview you may now see a warning that you are using deprecated components in your project. 

    To prevent any inconveniences, please keep your components up-to-date. 

    Clicking on a component from the list will take you to a component configuration, from where you can start a migration process.


    • Fixed issue in Orchestrator, when you changed notification settings during orchestrators run, the settings will return to previous values after orchestrator has finished. (github issue in Czech language)

    MySQL Transformations Failures

    We're encountering an increased number of application errors in MySQL transformations. We're looking into this issue and will update this post once we know more. This may also affect GoodData writer jobs.

    UPDATE Aug 21, 9:10pm PST

    The error seems to happens randomly on all Storage API async exports from tables stored on Snowflake. We have contacted Snowflake support to help us identify the root cause of the issue.

    You may encounter the error in any component that uses async exports from Snowflake or in any external integration exporting data from a Snowflake bucket. The error does not appear in Snowflake or Redshift transformations.

    UPDATE Aug 22, 9:45pm PST

    The error was not yet mitigated, Snowflake engineering team is looking into it. If you're encountering this problem, please contact us at support@keboola.com for a possible workaround.

    We're sorry for this inconvenience.

    UPDATE Aug 23, 5:24am PST

    Snowflake engineers has identified a potential fix for this issue but it is not deployed yet. Meanwhile we have found the workaround for the issue and we are updating the components. GoodData writer was fixed now, transformation and other components will be updated within few hours. 

    This issue is happening randomly and less than one percent of exports were affected.

    Week in Review -- August 21, 2017

    New Features

    • Database writers UI  - Disabled tables no longer load the whole content into the container when run and only first row of the table is loaded instead. This saves storage credits and decrease time of jobs run process. It works only for newly disabled tables, so old tables have to be redisabled (enable export -> disable export).
    • Python for transformations and custom science applications has been updated to version 3.6.2

    Week in Review -- August 14, 2017

    New Features

    • Ability to test component's image against live configurations (Read more in our documentation)
    • Markdown descriptions for tables and buckets are now available (see the images bellow)

    Fig. 1 Click "Describe the ..." to add description

    Fig. 2 Markdown is supported when describing buckets or tables.

    Description of buckets and tables can be added/edited in various places:

    • In bucket detail (Storage section),
    • in table detail (Storage section)
    • and anywhere in application where table preview is available


    • We finally turned off Legacy Routing (Original status here)
    • EOL of the synchronous exports has been announced and we'll turn it off on August 21st, 2017



    • Due to recent outages of Quay we started migration of our components to AWS ECR
    • We updated the Pigeon component to use the newer Storage API client and send files to File Uploads encrypted

    Snowflake Incident Investigation

    We were notified from Snowflake support about problem that could potentially affect Keboola Connection Snowflake Backed projects.

    The issue happened between 9:19pm UTC August 8th and 6:45pm August 9th UTC.

    There is a full alert from Snowflake below. We are investingating with them if we can find out if there are some affected KBC projects.

    We will keep you informed of any progress.

    UPDATE 2017-08-12 We have received list of projects which might be affected by this issue. In these projects one or more queries which might return wrong results were executed. We have notified these projects in KBC. If you need any assistance please contact support@keboola.com.

    Dear Snowflake Customer,

    We have identified a problem that could produce incorrect results in some queries that perform memory intensive join operations. It is unlikely that this issue impacts you; however, we wanted to make sure you were aware of the problem. The issue was isolated to the US-West region between 2:19pm Pacific time on Tuesday, August 8th and 11:45am Pacific time on Wednesday, August 9th. Queries performed in other regions or outside that timeframe were not impacted.

    Because of the nature of the issue, it is difficult for us to determine if any of your queries experienced the problem. However, we are able to perform further analysis on a query-by-query basis. If you have a question about whether a specific query was impacted, please submit a support request to Snowflake support via the Support Portal or via email to support@snowflake.net .

    We are very sorry about this issue and will do everything possible to help you resolve any problems this may have caused you.

    Components errors

    We observe components failures hosted on quay.io from 08:25  AM CET. Python Transformations, Facebook Extractor, Google Sheets Writer are between affected components.

    Quay.io outage is not reported yet. To avoid this issue in future we are moving all components to Keboola provided AWS repository.

    We will inform about the progress.

    9:09 AM CET RESOLVED Last error was seen at 08:53 AM CET. Quay.io has confirmed and fixed the issue.

    New Intercom Extractor

    Due to a change in the Intecom API authorization, the current extractor stopped working. It took us a while to go through the Intercom OAuth registration, but the result is here - the new Intercom Extractor. The current version is immediately deprecated, please configure and authorize the new extractor. You can start downloading your Intercom data in seconds.

    The full documentation is available here.

    End of life announcement for synchronous table exports

    The deprecated table synchronous exports will be shut down on 21st Aug 2017. 

    This API call was replaced by Asynchronous table export for full table unloads and Data Preview for small samples of table data.

    All Keboola Connection components use the new methods. As there are only a few projects currently using the deprecated method directly, these projects will be notified individually. For all other projects there is no action required.
