I have question regarding execution order of items in pipelines.
I have a pipeline with 3 stages s1, s2 and s3. Filter of these stages are set to 'serial_in_order'.
The pipeline is invoked within a parallel_while. Focus on two seperate invocation of s1 (these are within the parallel_while). Call them s1X and s1Y. Items of s1X (i.e s1X_1 s12X_ ... s1Xn_) are executed in serial order since its filter is set to 'serial_in_order'. The same is for s1Y (i.e item s1Y_1 s1Y_2 ... s1Y_m are executed in serial order). Is there execution order between s1X items and s1Y items? If '<' denotes 'executed before' order, can the following execution order happen s1X_1 < s1X_2 < s1Y_1 < .... < s1X_n < s1Y_2 < ...?
