Firstly, if **users want** to use temporary checkpoint location for
'**other sinks**', it is ok even if we will lost the processed data history.
User has the control of sql behavior.
Secondly, If users want to **continue** the process of data even for`
ConsoleSink` under the condition of 'set checkpoint location', we should give
the freedom to users. Again, users has the control of sql behavior.
