Autoreconnect

[MaxThom]

Hi, I would like the SDK to have some autoreconnect features and better status when its loose its connection and reocnnect. I could help work on this. This would really help make software with Surreal more reliable and easier to operate in a bigger system. People tend to not do autoreconnection in their softwares and operation team suffers from this. So if its baked in the sdk, it would help increase the reliability of Surreal thus its image.

I see two approaches to find down connectivity:

• test of connection every few seconds (tbd)
• when a request happens and it failed for connection issues (favorite)

When the connection fails, the socket is broken and we have to recreate it.

I see two options to fix it:

• we recreate to socket on each new db request
• we test the connection every few seconds, in the meantime, all request get discarded (favorite)

would be nice to have status handlers on connect, reconnect, loose connection and close so people can also act on them. Similar to NatsIO GoSDK

I found three librairies that implement that over gorilla ws. I think we should do it ourselves, but could draw inspiration:

• github.com/centrifugal/centrifuge-go
• https://github.com/sacOO7/gowebsocket
• https://github.com/recws-org/recws

What u guys think?

Hi @MaxThom!
Let me link #110 (comment) here. We are discussing the plan for the upcoming SDK v0.7.0, specifically regarding auto-reconnect, or a helper to make it easy.

sweet, that sound cool. Another thing I am thinking is having context pass to all the queries method would be nice so we can control timeout and else.

Thank you for confirming @MaxThom! JFYI, all the query methods are now context-aware since v0.6.0.
There's also a new context-aware Connect function to initialize the client, replacing and deprecating the existing non-context-aware New function.
