QUESTION
This is a follow-on or refinement to post How to add reactive object to secondary column header in output table?
The MWE code at the bottom produces a very nice secondary column header with embedded reactive object. This helps with the understandability of the transition table which shows the transitions FROM states along the columns (x-axis) and the transitions TO states along the rows (y-axis). The output is shown on the left side of the image below.
How would I do the same with a secondary row header with embedded reactive object, showing the TO periods (transTo
object)? As shown in the right half of the image below. I'm open to any other suggestions for rendering an understandable and user-friendly transition matrix. This sort of vertical text alignment is how I used to present transition tables in XLS; if the vertical text alignment is not feasible in this case I'm open to any solution!!
Note the full transition-matrix generating code expands/contracts automatically depending on the number of unique states in the data. This MWE code is static in that sense whereby the complete code is dynamic.
MWE code, with the invaluable assistance of ismirsehregal:

Answered 2022-Mar-24 at 13:37See post How to merge 2 row cells in data table? which provides a solution to showing reactive to/from values in a transition matrix. I believe it is a cleaner and more understandable table presentation than what is requested in this OP.
QUESTION
I am trying to achieve a fire and forget type of effect with webflux, thymeleaf and r2dbc. I have two endpoints, one to add an employee and another to list all employees. I want to simulate a slow database access so I have a thread sleep of several seconds before I call the DB.
Now, the effect I expect to see when I call /add
is that my controller returns immediately and the page add
is rendered at once. However, I'm not sure how to achieve this. With the current code nap()
happens before I can return a Mono
. In other words, I'm trying to run a long running job in the background without blocking the controller.
I have the following model:

Answered 2021-Nov-28 at 16:08I guess nap()
method executes Thread.sleep
or something similar, right? Thread.sleep
is blocking the main thread making the application unresponsive. You can use delayElements
operator to simulate a long-running operation:
