Upgrade to io.dropwizard.metrics version 4.2 about vertx-dropwizard-metrics

[vietj]

@tsegismont will check the feasibility of this with respect to Cassandra client that might prevent the upgrade

[tsegismont]

@vietj in Vert.x 4, the Cassandra client depends on the Datastax Java Driver 4.9.0 which allows to configure different metrics systems (Dropwizard 4, Micrometer 1.5, Microprofile Metrics).

By default, all Datastax Java Driver metrics are disabled but the Dropwizard module dependency is not optional.

So we could exclude the Dropwizard dependency in the Vert.x Cassandra Client.

Side note: as an exercise, I tried to configure a shared Micrometer registry for Vert.x and the Datastax Java Driver. It worked:

thanks for the heads up

what if somebody wants to use Cassandra specific dropwizard metrics ?

[tsegismont]

@vietj then they'd have to:

• re-add the dependency on Dropwizard 4
• maintain a Vert.x Metrics SPI implementation with Dropwizard 4

Actually I'm not sure what's the rationale for this issue. Do you remember why you filed it?

If you look at the Dropwizard dev status table, Dropwizard 5 is marked on-pause.
Besides, both Vert.x Dropwizard and DataStax Java Driver depend on Dropwizard 4.0.x.

So it seems to me all is well :-)

[vietj]

I think it was filed when Dropwizard 5 was a thing ?

[vietj]

shall we try upgrade to release/4.2.x branch ?

[tsegismont]

The Dropwizard website promotes the version 4.1. Version 4.2 is still marked as "in-development."

If we were to upgrade, version 4.1 sounds like the target to me.

[tsegismont]

I asked the Dropwizard team about the 4.2 status. They have a beta3 out already and only a handful of remaining issues and said it should be released soon-ish

Not closed yet. DZ has been upgrade to 4.2 RC2 for 4.1 first beta.
