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

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

Deprecation

  • 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

Tutorials

Fixes

  • 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.
