----------------------------------------------------------------
[~roman_khachatryan] It's not truncated. It's just that the TableSourceScan
part does not appear. The task name in the detail tab on the right will not be
truncated, however the TableSourceScan part still doesn't appear. The #2
TableSourceScan indicates that its an input of the multiple input operator and
is included in the name of the MultipleInputOperator (we display all inputs of
the multiple input operator in its name), which is not that obvious for the
user to tell that there is a chained source.
Indeed, one can argue that source chaining is currently only implemented for
multiple input tasks, so it seems to be sufficient that chained sources are
hinted in the multiple input operators. However source chaining is related more
to operator chaining rather than an operator in the table API. If we implement
source chaining for two-input operators in the future, then users will have no
way to tell whether there is a chained source or not.
