In > particular, the Row values will be encoded without a Length Prefix, but then > be requested to decode them with a length prefix, which wasn't included. > This is similar to the issue in BEAM-12438 which has been hacked around. > In this instance it's likely more resilient to always length prefix Row > encoded types, and make it explicit in the pipeline proto. This should avoid > issues with runners having odd behaviors WRT row coders at this time, while > not preventing them from introspecting row encoded values should they chose. > This may also allow us to avoid the hack for BEAM-12438, though that is > something to be verified independently. -- This message was sent by Atlassian Jira (v8.20.1#820001)
