The submission system is single-node Java based microservice with a RESTful API that powers a SPA (Single Page Application) front-end. Users interact with the system by way of the UI, API as well as an SFTP interface for uploading files.
Additional user guides may be found on the ICGC DCC Docs site.
The backend Java modules rely heavily on Lombok to minimize boilerplate code and type noise that is typical of Java applications.
System metadata and user submitted files are handled separately within the system. Metadata is stored in MongoDB while files are stored in Hadoop HDFS.
All files are directly streamed from SFTP to HDFS
Files are stored in the following directory structure:
[baseDir]/ICGC{release}/{projectCode}
where baseDir is the root path in HDFS, {release} is a release number, and {projectCode} is a system registered project code.
Metadata is stored in MongoDB with a simple schema, comprised of the following collections, organized by function:
CodeListDictionary
ProjectUser
Release
ProjectDataTypeReportProjectSequencingStrategyReport
Which stores the following reports
ProjectDataTypeReport |
