I'm writing a node/es app using the es javascript api....
Is there any reason to use pooling for all the javascript clients? Or
should I just use one client for the app?
Thanks,
phil

no answer, so let me ask a different way. how are most of the es
javascript client apps managing the instance of the client?
do you have one es client per app (singleton) that all requests go
through? Do you create and destroy clients for every request? Do you use
a es client pool using something like
[GitHub - coopernurse/node-pool: Generic resource pooling for node.js](https://github.com/coopernurse/node-pool) ?
Thanks for any comments!

On my platform, there is one and only one es client, through which all
requests go. It seems to work well, though "well" is defined as having just
a few people using it at one time. We plan to start stress testing the
system soon.
Cheers
