Many realtime

Hi,
I've many realtime provider on my app, but something some of them return null when subscribing, so I never get any update.

I use riverpod for managing my provider. I've found a way to solve it by creating many instance for my realtime provider, but I don't know if it is a good practice.

Can I create many realtime client like this :
final realtime = Realtime(client);
and create a subscription

Or the best way is to create only one client and many subscription ?

Every time you're running.

final realtime = Realtime(client);

You're creating a new socket to your server which can become overwhelming pretty fast.

I think the best way would be one client with multiple subscriptions, and check each time what you got. And in case you got null / empty ones just ignore them.

Yes, but when I do this, some subscription return me null and I never get notified :/

You get a completely null? like all the is just null?

Yes, in the log, i got only "subscription : null", it come from this line : "debugPrint('subscription: $_lastUrl');" in the method _createSocket in the class RealtimeMixin.

Are you running against Appwrite cloud or a self-hosted one?

self hosted (1.2.1)

So you can run

  docker logs appwrite-realtime

To see if any obvious errors are shown.

Also, when you can backup, and upgrade your instance. (using migration scripts)

Yes, it is planned, i'll do that next week 🙂

Have you seen anything suspicious in the logs?

I've just receive a null subscription on my client, but on the server, nothing warm me : Connection open (user: 2025) Connection open (user: 2026) Connection open (user: 2027) Connection open (user: 2028) Connection close: 2020 Connection open (user: 2029) Connection open (user: 2030) Connection close: 2030 Connection open (user: 2031) Connection close: 2031 Connection close: 2029 Connection open (user: 2032) Connection close: 2025 Connection close: 2028 Connection close: 2026 Connection close: 2027 Connection open (user: 2033) Connection open (user: 2034) Connection open (user: 2035) Connection open (user: 2036) Connection open (user: 2037) Connection close: 2035 Connection open (user: 2038) Connection close: 2038 Connection open (user: 2039) Connection close: 2037 Connection open (user: 2040) Connection close: 2040 Connection open (user: 2041) Connection open (user: 2042) Connection open (user: 2043) Connection close: 2036 Connection close: 2033 Connection close: 2034 Connection close: 2039 Connection open (user: 2044) Connection close: 2043 Connection close: 2042 Connection close: 2041 Connection open (user: 2045) Connection close: 2044 Connection open (user: 2046) Connection close: 2046 Connection open (user: 2047) Connection open (user: 2048) Connection open (user: 2049) Connection open (user: 2050) Connection open (user: 2051) Connection close: 2051 Connection open (user: 2052) Connection open (user: 2053) Connection open (user: 2054)
