Domain Layer Schema

Summary

This document describes Apache DevLake's domain layer schema.

Referring to DevLake's architecture, the data in the domain layer is transformed from the data in the tool layer. The tool layer schema is based on the data from specific tools such as Jira, GitHub, GitLab, Jenkins, etc. The domain layer schema can be regarded as an abstraction of tool-layer schemas.

DevLake Dataflow

Use Cases

  1. All metrics from pre-built dashboards are based on this data schema.
  2. As a user, you can create your own customized dashboards based on this data schema.
  3. As a contributor, you can refer to this data schema while working on the ETL logic when adding/updating data source plugins.

Data Models

This is the up-to-date domain layer schema for DevLake. Tables (entities) are categorized into 5 domains.

  1. Issue tracking: Jira issues, GitHub issues, GitLab issues, etc.
  2. Source code management: Git/GitHub/GitLab commits and refs(tags and branches), etc.
  3. Code review: GitHub PRs, GitLab MRs, etc.
  4. CI/CD: Jenkins jobs & builds, etc.
  5. Code Quality: SonarQube issues, hotspots, file metrics, etc.
  6. Cross-domain: entities that map entities from different domains to break data isolation.

Schema Diagram

Domain Layer Schema

When reading the schema, you'll notice that many tables' primary key is called id. Unlike auto-increment id or UUID, id is a string composed of several parts to uniquely identify similar entities (e.g. repo) from different platforms (e.g. GitHub/GitLab) and allow them to co-exist in a single table.

Tables that end with WIP are still under development.

Naming Conventions

  1. The name of a table is in plural form. E.g. boards, issues, etc.
  2. The name of a table which describe the relation between 2 entities is in the form of [BigEntity in singular form]_[SmallEntity in plural form]. E.g. board_issues, sprint_issues, pull_request_comments, etc.
  3. Value of the field in enum type are in capital letters. E.g. table.issues.type has 3 values, REQUIREMENT, BUG, INCIDENT. Values that are phrases, such as 'IN_PROGRESS' of table.issues.status, are separated with underscore '_'.

How to Customize Data Models

Apache DevLake provides 2 plugins:

  • customize: to create/delete columns in the domain layer schema with the data extracted from raw layer tables
  • dbt: to transform data based on the domain layer schema and generate new tables

Domain 1 - Issue Tracking

issues

An issue is the abstraction of GitHub/GitLab/BitBucket/Jira/TAPD/Zentao... issues.

fieldtypelengthdescriptionkey
idvarchar255An issue's id is composed of < plugin >:< Entity >:< PK0 >[:PK1]..."
  • For Github issues, a Github issue's id is like "github:GithubIssues:< GithubIssueId >". E.g. 'github:GithubIssues:1049355647'
  • For Jira issues, a Github repo's id is like "jira:JiraIssues:< JiraSourceId >:< JiraIssueId >". E.g. 'jira:JiraIssues:1:10063'. < JiraSourceId > is used to identify which jira source the issue came from, since DevLake users can import data from several different Jira instances at the same time.
PK
issue_keyvarchar255The key of this issue. For example, the key of this Github issue is 1145.
urlvarchar255The url of the issue. It's a web address in most cases.

typevarchar100The standard type of this issue. There are 3 standard types:
  • REQUIREMENT: this issue is a feature
  • BUG: this issue is a bug found during test
  • INCIDENT: this issue is a bug found after release
The 3 standard types are transformed from the original types of an issue. The transformation rule is set in the '.env' file or 'config-ui' before data collection. For issues with an original type that has not mapped to a standard type, the value of type will be the issue's original type.
original_typevarchar100The original type of an issue.
statusvarchar100The standard statuses of this issue. There are 3 standard statuses:
  • TODO: this issue is in backlog or to-do list

The 3 standard statuses are transformed from the original statuses of an issue. The transformation rule:
  • For Jira issue status: transformed from the Jira issue's statusCategory. Jira issue has 3 default status categories: 'To Do', 'In Progress', 'Done'.
  • For Github issue status:
    • open -> TODO
    • closed -> DONE

cicd_deployments

A cicd_deployment refers to a deployment at the project level. In the case where a pipeline run or build deploys across three distinct repositories, it will be categorized as ONE cicd_deployment while being recorded as THREE separate cicd_deployment_commits. It may come from several sources:

  • Domain layer cicd_pipelines, such as GitHub workflow runs, GitLab pipelines, Jenkins builds and BitBucket pipelines, etc. Deployments from cicd_pipelines will be transformed according to the regex configuration set in the Blueprint transformation before adding to this table.
  • Tool layer deployments: in v0.20, only the BitBucket\Bamboo\GitLab and GitHub(Use GraphQL APIs) plugins collect the independent deployment entity which you can find in table._tool_bitbucket_deployments and _tool_bamboo_deploy_builds, there will be more in the future.
  • Deployments pushed directly from webhooks

Additional Notes

  • CICD deployments are recorded at the project level, not the repository level.
  • CICD deployment commits are individual commits that represent a single deployment across multiple repositories.

cicd_deployment_commits

A cicd_deployment_commit is a deployment in a specific repo. A deployment may come from several sources:

  • Domain layer cicd_pipelines, such as GitHub workflow runs, GitLab pipelines, Jenkins builds and BitBucket pipelines, etc. Deployments from cicd_pipelines will be transformed according to the regex configuration set in the Blueprint transformation before adding to this table.
  • Tool layer deployments: in v0.18, only the BitBucket and Bamboo plugins collect the independent deployment entity which you can find in table._tool_bitbucket_deployments and _tool_bamboo_deploy_builds, but there will be more in the future.
  • Deployments pushed directly from webhooks

You can query deployments from this table by SELECT DISTINCT cicd_deployment_id FROM cicd_deployment_commits.

Normally, one deployment only deploy to one repo. But in some cases, one deployment may deploy in multiple repos with different commits. In these cases, there will be multiple pairs of deployment-commit-repo, appeared in multiple entries in this table.

Domain 6 - Cross-Domain Entities

These entities are used to map entities between different domains. They are the key players to break data isolation.

There are low-level entities such as issue_commits, users, and higher-level cross domain entities such as board_repos

issue_commits

A low-level mapping between "issue tracking" and "source code management" domain by mapping issues and commits. Issue(n): Commit(n).

The original connection between these two entities lies in either issue tracking tools like Jira or source code management tools like GitLab. You have to use tools to accomplish this.

For example, a common method to connect Jira issue and GitLab commit is a GitLab plugin Jira Integration. With this plugin, the Jira issue key in the commit message written by the committers will be parsed. Then, the plugin will add the commit urls under this jira issue. Hence, DevLake's Jira plugin can get the related commits (including repo, commit_id, url) of an issue.

pull_request_issues

This table shows the issues closed by pull requests. It's a medium-level mapping between "issue tracking" and "source code management" domain by mapping issues and commits. Issue(n): Commit(n).

Get Domain Layer Models in Developer Mode

When developing a new plugin, you need to refer to domain layer models, as all raw data should be transformed to domain layer data to provide standardized metrics across tools. Please use the following method to access the domain data models.

import "github.com/apache/incubator-devlake/models/domainlayer/domaininfo"

domaininfo := domaininfo.GetDomainTablesInfo()
for _, table := range domaininfo {
// do something
}

If you want to learn more about plugin models, please visit PluginImplementation
