> 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,
