[Odonno]

• Add Open event to detect when started to listen to Live Query
• Change tests and fixes ObserveQuery/ObserveTable, using a cold Observable

Could this be extended to use System.Threading.Channels.ChannelReader<T>?

It might allow for flexibility in consumption and better handling of back pressure

Hi Simon.

I don't fully understand. What part of the code are you talking about?

Live Query are already using unbounded Channel<T>, using both a ChannelWriter<T> and ChannelReader<T> underneath. See the class here: https://github.com/surrealdb/surrealdb.net/blob/main/SurrealDb.Net/Internals/Models/LiveQuery/SurrealDbLiveQueryChannel.cs

Ahh, apologies. I was on my phone and didn't see that you already had a wrapper for it.
