[my-component-37670563-39be-4fcb-92e1-02f115aca43c-StreamThread-2] ERROR 
o.a.k.s.p.i.AssignedTasks - stream-thread 
[my-component-37670563-39be-4fcb-92e1-02f115aca43c-StreamThread-2] Failed to 
commit stream task 1_1 due to the following error:
org.apache.kafka.streams.errors.StreamsException: task [1_1] Abort sending 
since an error caught with a previous record (key [my-key] value [my-value] ...
{code}
In some environments, this is highly undesired behavior since the values can 
contain sensitive information. Error logs are usually collected to separate 
systems not meant for storing such information (e.g. patient or financial data).
