> Hi,
> We have updated from Kylin 2.2 to Kylin 2.3.1. We performed the update
> process with successful. However, we have experimented an increase of time
> wasted between steps during building time. For example, the time between step
> 7 “Build N-Dimension Cuboid:level 1” and “…level2” is now about 30 seconds, a
> lot of time if we take into account that in these steps no processing is
> executed since we use the "layer" algorithm (Screenshot 1). This time between
> steps is much longer than when we used Kylin 2.2, were average time was about
> 5 seconds. (Screenshot 2).
> Could it be related to a change in the code? The configuration we use in
> Kylin 2.3.1 is the same as we used in Kylin 2.2. I have considered this JIRA
> as a possible BUG.
> Thanks in advance,
