hi experts, i've a running realtime table that gets data from kafka running, today when I checked for new incoming data, i've got this error, any ideas what that could be?

The error states:

Invalid format: "2021-06-10 10:42:25" is too short

what that could mean? because the job was actually working with no issues

this is while creating segment from realtime stream (which happens periodically). You may want to check if your datetime fieldspec is defined correctly and the incoming stream follows the format you specified

hmm great tip i'll do that @Mayank thank you for the tip
