exception / error handling in the data flow

[KrishnaPG]

Not sure if this is the right repo or should be posted elsewhere, but we have this below question:

How to deal with errors that could arise out of any one component in the flow pipeline?

For example, say read elastic

• we would like to handle the errors in a peaceful manner (instead of breaking / halting the whole pipeline). For example, can we catch 'server not found / dns errors / network errors etc' and log them into a file with timestamp (and follow the regular code flow in case no error happens) ??
