Why does the onEventAppeared never get called in my code?

EventStoreDB
#1

I am trying to read all the events in my EventStore. Here is how I am trying to accomplish this

connection.readAllEventsForward(

-1,

-1,

1000000,

false,

false,

e => console.log(“EVENT”, e),

credentials,

() => console.log(“All events read”)

);

I always get to the “All events read” message, but nothing happens for each event in the store. I am positive there are events in the store, so something should come out. Is this being processed incorrectly with the function logging out the events? What am I doing wrong?

#2

Maybe I don’t fully understand what readAllEventsForward does? When I changed the callback to be
completed => console.log(completed)

, there was an empty array of events in the completed object. I thought readAllEventsForward, read all of the events. Am I mistaken? If I am mistaken, how do I get all the events out of the ES?

#3

And I have an error.
error: ‘Read size too big, should be less than 4096 items’

I assumed I could read as many items as I wanted. Is there a way to go through all of the events in the store?

#4

that is the batch size not the total number to read

#5

So in
connection.readAllEventsForward(
-1,

-1,

1000,

false,

false,

e => console.log(“EVENT”, e),

credentials,

() => console.log(“All events read”)

);

The third argument is batch size. I assume that means that the streams are returned from the ES in batches of whatever that 3rd parameter is. Is this correct? Bc if I change that number to something small, like 100, then it seems to only return 100 events. I can verify that it doesn’t return all of the events. The parameter name is maxCount, so I assumed it was the total number of events that would return.

So in
-1,

1000,

false,

false,

e => console.log(“EVENT”, e),

);

connection.readAllEventsForward(
