hello,
i have a process where i want to take an input from kafka then send to an api and get back the results from the api, the kafka input also has some values that i already parsed, but then i want to join the api response with the values that i parsed using a column that is common between the two outputs, but talend does not allow me to do that for some reason.
can i even do that ??
here are some screenshots from what i am trying to do
i just want to join row 4 with "out_logs" from the tmap
here is the map
Now whenever i try to join talend wont allow me, i cant do this
here's the tmap configuration
I also tried putting two tkafka input componenets for the same topic then join them, but only 1 tkafka input component work at a time, they didnt not work at the same time.
any help ??
thanks manodwhb
I tried tHashoutput, but it does not work in real time either
i tried this and it gave me the error "The hash is not initialized : The hash must exist before you read from it" (i guess i know why )
also i tried this, but while running, it never starts the joining subjob
any help would be apperciated.
thanks
thanks again for your reply Manohar.
the joing subjob does not work either (no errors or anything, it just doest start)
what i've noticed, that since tkafkainput is a kafka consumer the kafka subjob will keep running until i kill it ( it is listenining to the kafka topic in real time)
so, my assumption is that the joining subjob will never start because the kafka subjob will never stop.
is there any way to force start it ??
if not, allow me to bring back this
is there is anyway in talend that i can start tHashInput_1 after tHashoutput_1 ??
thanks again Manohar.
