HTTP webClient pools

[Rui Silva]

Hi!

I have a doubt related with webClients (we are using the implementation from Rx: io.vertx.rxjava3.ext.web.client.WebClient) and their connection pools.

If my application has 2 distinct webClient references, but they point to the same target/destination, will their connection pools be shared or will they be independent from each other?

For example, if I have a webClient A pointing to target T with max pool size of 10 and another webClient B, also pointing to target T, and also with max pool size of 10, what will happen? Will these connections pools be completely independent? So, 10 connections for each web client? Or they will be shared and thus, a max of 20 connections for both clients?

Note: both web clients are running in a single verticle instance.

Thanks!

hi,

each web client has its pool.

since recently you can use a shared pool that will use the same
underlying pool:
https://vertx.io/docs/vertx-core/java/#_client_sharing

it should work equally with the WebClient
