What is media type versioning?
Media type versioning provides the ability to use the same URI for multiple versions of an API, by specifying the version as part of the Accept media type. The Accept header can provide versioning in two different ways: As part of the media type name itself: application/vnd.
What are the versioning options that are available?
There are four common ways to version a REST API.
- Versioning through URI Path.
- Versioning through query parameters.
- Versioning through custom headers.
- Versioning through content negotiation.
What is Jaxrs Jersey?
JAX-RS is an specification (just a definition) and Jersey is a JAX-RS implementation. Jersey framework is more than the JAX-RS Reference Implementation. Jersey provides its own API that extend the JAX-RS toolkit with additional features and utilities to further simplify RESTful service and client development.
When should I use API versioning?
APIs only need to be up-versioned when a breaking change is made.
- a change in the format of the response data for one or more calls.
- a change in the request or response type (i.e. changing an integer to a float)
- removing any part of the API.
What is the most common method of versioning a REST API?
URI path versioning
There are several methods for managing the version of your API. URI path versioning is the most common.
What is major minor and patch version?
MAJOR version increment indicates incompatible API changes. MINOR version increment indicates addition of functionality in a backwards-compatible manner. PATCH version increment indicates backwards-compatible bug fixes.
What does API v2 mean?
The v2 API is a modernized self-documenting API interface covering most current Solr APIs. It is anticipated that once the v2 API reaches full coverage, and Solr-internal API usages like SolrJ and the Admin UI have been converted from the old API to the v2 API, the old API will eventually be retired.
What is V3 API?
The new V3 API provides fast, easy access to MBTA schedules, alerts, and real-time information. The V3 API uses the JSON API format, so you can get started quickly using any of the available libraries. V3 API documentation is available using Swagger.
What is media type versioning and Uri versioning?
URI Versioning – version the URI space using version indicators Media Type Versioning – version the Representation of the Resource When we introduce the version in the URI space, the Representations of Resources are considered immutable. So when changes need to be introduced in the API, a new URI space needs to be created.
What happens when an API version is changed?
If part of the API moves to the new version, then the entire API has to move along with it. This also makes upgrading clients from v1 to v2 a major undertaking – which leads to slower upgrades and much longer sunset periods for the old versions.
What happens if I change the Uri version of an API?
If the URI is versioned, then the cache will need to keep multiple copies of each Resource – one for every version of the API. This puts a load on the cache and decreases the cache hit rate since different clients will use different versions. Also, some cache invalidation mechanisms will no longer work.
Why is it easier to cache media types than Uris?
From the perspective of client caching however, the solution that versions the media type involves slightly more work than the one where URIs contain the version identifier. This is because it’s simply easier to cache something when its key is an URL than a media type.
