help: Delay Agent implementation

[carmatana]

Hello,

I cannot make Delay Agent work.

I am trying to:

(1) I have a list of stock symbols (i.e.: AAPL, GOOGL, etc.)

(2) I get with Website Agent their prices and other data (an event per symbol)

(3) Write this info in a file (an event per symbol)

(4) (THIS IS THE PART THAT IS NOT WORKING) Buffer all events in (3) with Delay Agent and after a while emit an event to the next agent that is:

(5) Read the file info (1 event for ALL symbols)

(6) Format the info

(7) Send a pushover

---

What I wan to achieve is to have all the symbols written in the file and AFTER everything is written, read the file.

This is a partial view of my flow:

My Delay Agent settings:

"max_events": "2", (this is the number of stock symbols I have in my tests)
"keep": "newest",
"max_emitted_events": "1", (I want only want event to be emitted)
"emit_interval": "60", (I would expect that after 60 seconds an event is emitted to the next agent to trigger it)

If I delete the Delay Agent from the flow, the read agent runs multiple times, 1 per writing event.

I want to have the Read Agent run only once, after all the writing has been done.

---

Any idea how to achieve this ?

I know that I can run the Read Agent with an scheduler, with enough time to ensure that the writing has been done. But I want to try the Delay Agent way.

Thanks for the attention and help !
