Release 4.1.0

Happy 18th Birthday HAPI

HAPI HL7v2 v0.1 was released on

November 15 2001

​

This is our 42nd major release!

HAPI FHIR: What's New

ValueSet Precalculation

• Mostly invisible feature with a huge impact
• ValueSet expansions are now automatically calculated and cached in a background job
• This change allows expansion of very large ValueSets
• Most importantly: this change dramatically improves validation performance

HAPI FHIR: What's New

HAPI FHIR: What's New

Bulk Export Support

• Bulk Export allows a background export job to generate “extract files” with all or a useful subset of your FHIR data
• Currently only system-level export is supported (more planned)

​

HAPI FHIR: What's New

ElasticSearch Support

• Lucene Indexes are used for fulltext indexing, and to power HAPI FHIR Terminology Services
• ElasticSearch may now be used as a fully supported alternative, which is great for scalability
• See the hapi-fhir-jpaserver-starter project for details on setup

Note: We may consider deprecating Raw Lucene mode in the future but this is not currently planned

​

HAPI FHIR: What's New

Terminology Delta Operations

• As implementers roll FHIR repositories into more large-scale production systems, we recognize a need to live terminology maintenance
• New “delta operations” allow hot patching of CodeSystems by adding/removing sets of codes and hierarchy entries

See: https://smilecdr.com/docs/fhir_repository/terminology.html#delta-add-operation-apply-codesystem-delta-add

​

HAPI FHIR: What's New

Externalized Binary and DocumentReference

• Igloo release introduced Externalized Binary Storage mode
• Repositories can now be configured to automatically offload binary payloads found within Binary (and similar) resources into Externalized Binary Storage

HAPI FHIR: What's New

JSON Serializer Performance Improvement

• A contributed pull request was merged that improves JSON serialization performance by 20-50%!

2019.11.R01

Next Quarterly Release

• This is our 12th release since we formally launched Smile CDR

Smile CDR: What's New

LiveBundles

• LiveBundles are a feature that allows large and potentially complex/costly tables of data to be kept up to date using FHIR CDR data

​

Smile CDR: What's New

Infinispan Query Cache

• The query cache can now be offloaded into an external optimized store
• This is particularly useful for very high volume deployments (1000s of searches per second) as it reduces pressure on the RDBMS
• RedHat Infinispan is our first target, others may be added in the future (e.g. Redis, Memcached)

​

Smile CDR: What's New

Request Source and Transaction ID Tracking

• Transactions are all now tagged with (either/both) a source system and a unique request ID
• These IDs can be traced in the CDR Transaction Log, and can be used to bind requests to broader application context (e.g. using systems such as DynaTrace)

​

Smile CDR: What's New

Javascript Credential Management API

• A new scripting API allows system credentials (such as database passwords) to be fetched from an external credential store such as CyberArk Conjur

​

Smile CDR: What's New

3rd Party OIDC Server Integration Tutorial

• An increasingly common pattern is the integration of a Smile CDR repository with a 3rd-party OIDC server (e.g. MitreID Connect, Okta, etc)
• A complete tutorial has been added to describe the ways this can be achieved

​

What's Coming

What's Coming

Bulk Import (HAPI FHIR + Smile CDR)

• Now that Bulk Export is complete, we will be working on support for Bulk Import in order to support large data imports

​

​

What's Coming

Task Scheduler API (HAPI FHIR + Smile CDR)

• FHIR Repositories now have many background tasks with little visibility:
• Bulk Export
• Manual Subscription Triggering
• Cleanup jobs
• Custom Search Parameter Reindexing
• A new API is being developed which will improve visibility into these jobs

​

​

What's Coming

Stateless Clustering (Smile CDR)

• Current “N master + M clones” design for clustering has proven challenging in docker/k8s based deployments
• We are working on a design to allow the concept of “clone nodes” to be removed entirely, which should greatly simplify clustering devops

​

​

What's Coming

MongoDB Support (Smile CDR)

• A new FHIR Storage module based on MongoDB is in the final stages of development
• MongoDB Storage is intended for ultra-high performance scenarios
• We are already producing pre-release builds, please let us know if you are interested

​

​

What's Coming

HAPI FHIR Website Relaunch

• Watch for a completely redesigned HAPI FHIR website in the coming weeks
• We will be introducing a global HAPI FHIR atlas inspired by the (beautiful) OpenMRS Atlas: https://atlas.openmrs.org/
• Reminder to fill out our community survey: http://bit.ly/33HO4cs
