MetaCPAN V1 announcement and migration plan

V1 - announcement and migration plan

We are pleased to announce a new version of the MetaCPAN.. v1.. IS NOW LIVE (2016-11-20)!

This document has been updated now that we are live...

Advantages

• Speed
• Resilience
• New Elasticsearch search features

Front end:

https://metacpan.org/

API

https://fastapi.metacpan.org/v1/

This is backed by a 3 node version 2.3 Elasticsearch cluster (rather than single node running ES 0.2!). It is also served through Fastly our CDN, which will provide better world wide routing and we are now using it to cache some requests.

Breaking changes

• GET requests with a request body will no longer work
• Any features Elasticsearch 2.3 no longer supports
• Stricter mapping matches (mostly for indexing, though this includes author.json files from PAUSE)
• /v1/ will be required in the path, previously it was optional

Support for the old https://api.metacpan.org/v0/

We are committed to running https://api.metacpan.org/v0/ until at least 2017-06-01, nearer the time we will review what traffic is still hitting this end point, we will then work out what (if any) provision we need to make for the existing traffic. We expect some clients (specifically App::cpanminus) may need longer term support.

NOTE: user specific data (faves etc) is only updated on the v1 end point
