Loading SNOMED CT into Snowstorm

First download the most recent SNOMED CT International Edition RF2 release files release files.

Then make sure Elasticsearch is running and choose one of the sections below.

Loading Release Snapshot

This loads the content of the current release and skips loading outdated content. This is the recommended option.

To delete any existing Snowstorm Elasticsearch indices and load the RF2 Snapshot start Snowstorm with the following arguments:

java -Xms2g -Xmx4g -jar target/snowstorm*.jar --delete-indices --import=<Absolute-path-of-SNOMED-CT-RF2-zip>

This will take between 30-60 minutes depending on the performance of your machine.

Loading Release Full Files

It's possible to load the RF2 Full files which gives you access to previous releases in addition to the current content. This will take many hours (one import has taken more than 24 hours).

Simply replace the --import argument above with --import-full.
