Planing to migrate from driver cassandra to lua-cassandra

[leandromoreira]

Since the cassandra driver is not in active development we're planning to move on to this 🥇 awesome project.

I would like to know how different the API is from cassandra? socket options and client

Hi,

Glad to hear! The API for the single module is pretty much the same, but the usage of the clustering module differs a bit more, especially with the necessity to store the cluster instance as a local upvalue. Everything is documented online:

https://thibaultcha.github.io/lua-cassandra/

Depending on your cluster, you might want to look at the different load balancing policies and the desired level of consistency too.

Thank you @thibaultcha, I'll be posting here any issues or advice for anyone in the same situation.

FYI, these days work is being done on the refactor/perf+style branch and will likely result in a more friendly cluster interface (I'd like to avoid the need for users to cache the instance themselves in an upvalue). But this is not before a while.

Let's now close this, if you have further questions, feel free to open another issue.

We postpone but we'll do it this quarter! I'll keep this up to date, thanks.

Hi @thibaultcha, just a sanity check related to this migration, there isn't setkeepalive function for cluster module, can I assume that the coordinator does that by default?

[thibaultcha]

@rafatio Yes indeed!

@thibaultcha nice :) Testing the cluster driver we are having some could not refresh cluster: no host details for and no host details for. Is those errors usual or there is something wrong?
