Robert Metzger commented on FLINK-27721: ---------------------------------------- Thank you all for the positive responses. bq. Does it have a limit on how many messages / data it can store? We are currently on the free plan, which offers "Unlimited message retention history". I have exported all public messages from our Slack instance, and uploaded it to linen.dev. So the archive shows messages from day one, and it should sync automatically from now on. bq. My biggest concern is related to the privacy statement / how will they earn money I share that concern. They might at some point put up ads or limit the features of the free plan. I will ask them about this. bq. Based on the currently used ASF Privacy Policy, that's not covered Thanks for bringing this up. Based on my understanding, the ASF PP is only covering data usage on ASF premises. The Apache Flink Slack is hosted by Slack Inc, so users signing up for the Flink Slack have to accept / agree to Slack's PP, not the ASF PP. > Slack: set up archive > --------------------- > > Key: FLINK-27721 > URL: https://issues.apache.org/jira/browse/FLINK-27721 > Project: Flink > Issue Type: Sub-task > Reporter: Xintong Song > Assignee: Xintong Song > Priority: Major > -- This message was sent by Atlassian Jira (v8.20.10#820010)
