[email]: After creating the LKIP and writing the preliminary content, start a discussion on the LKIP proposal. Currently, the discussion must be initiated in the WeChat group [Apache Linkis Community Development Group], and the minutes can be sent to the official dev mailbox of linkis. The email address for the minutes can be placed here
[Release]: The (planned) release version of Linkis
[Proposer]：

Motivation & Background

When the current linkis entrance is executed, the user needs to associate the userCreator and tenant to the ECM, and the tenant label is automatically matched. The purpose is to no longer associate the user with the userCreator and tenant. linkis automatically matches the identifier to the user's execution task by configuring

Basic concept

Expect to achieve goals

linkis does not require users to add tags by themselves, but is added to the execution tasks by linkis, users only need to configure

Implementation plan

By intercepting, get the jobRequest, get the user's information, match the label information configured by the user, and then add the label information to the execution task.

flow chart:

Function realization
a) Data cache
● Cache tenant tag table information (the principle is the same as that of sensitive table interception and cache data)
● When the configuration table is updated, the cache is updated (increased)
b) Data configuration
● Add a new page for data configuration demo: hadoop-IDE can be associated with tenant1
● The configuration relationship can only be one label per user. demo:hadoop-IDE is associated based on user-creatorLabel
● Tenant can be configured
● When adding or modifying, determine the ECM resource corresponding to the tenant. If there is no corresponding tenant, an error message will be displayed, "Add/modify failed, contact the administrator to add the ECM corresponding to the label"
● Automatically insert configuration for new users to do label judgment
● monitor configuration detection alarm

Compatibility, Deprecation, and Migration Plan

  • What impact (if any) will there be on existing users?
  • If we are changing behavior, how will we phase out the older behavior?
  • If we require special migration tools, describe them here.
  • When will we remove the existing behavior?


  • No labels
