WEBVTT--> everybody have completed any questions on there are any question that you want to discuss --> then I have fixed the cluster on the topics yesterday like there is an issue with the --> WS where it is not able to accept the request now I will give you the link where you can try out --> the game once you try it out we'll check the monitoring and see how the topics are getting --> then we will go ahead and install the Grafana and permittance to see in our own system --> yeah if you are able to open the one which I have pinned you should be able to see dashboard like this --> while we go through I will check the topics and see first I will go and check the user --> game see the messages how they are coming in you see for every 20 seconds we get an --> user with the score and the lives and the weight the level is this is one of the topic --> which listens to the messages coming in from specific user so let's see the stream image --> how actually the whole workflow goes through you see there are 3 49 producers why there are --> 3 49 producers basically like every time you do play there is an asynchronously happens --> using the lambda function like it triggers the serverless option and inside the serverless --> it will push the message to the topic these are all the different producers producing data --> so ideally what happens is in this case every time a new producer comes in he will actually --> produce only one message he will not produce multiple because every time it triggers a --> new event internally from the application point of view so then those producers --> whatever it is producing it is going to the topic user game and we can see the --> number of partitions here and what is the bytes in and out what is the bytes we are --> getting in and what is the bytes we are getting out and also the messages in and messages --> out from the topic and we can see the retention time how long we can keep as --> of now I kept it as 1 hour and retention size I have set it to infinite it depends --> by comparing whatever the value we want and we have the cleaner policy estimate --> here from here we have 2 ksql queries that we have added one is stats per user --> that means we need the details of every user highest score that we will take it off --> here and the summary stats is basically like the whole whoever has still played till now --> it will be a summary of all those details
