-------------------------------------
Summary: Should provide a REST API to allow users to build
specific indexes
Key: KYLIN-5572
URL: https://issues.apache.org/jira/browse/KYLIN-5572
Project: Kylin
Issue Type: New Feature
Components: Modeling, REST Service
Affects Versions: 5.0-alpha
Reporter: Guangyuan Feng
Fix For: 5.0-alpha
Our product (KC 4.5.22.2) currently doesn’t support building specific indexes
through API. Users can only refresh the whole segments to rebuild some of the
indexes in the segment which is very inefficient. However, the same capability
is available in the UI. Therefore, UBS wants to have a REST API to provide:
# The ability to build specific indexes instead of all indexes in segments
# The indexes to be built can be specified by *indexes ID or(and) status.*
Status can be any valid status of indexes, for example, NO BUILD, ONLINE, etc.
# The response of this API should return the job ID for further tracking
Why should we provide this API? (Business Impact)
Without this API, users can only rely on a *Kyligence ADMIN* to operate index
building for each team from UI or simply rebuild the whole segment. In UBS, all
operations on production have to be automated. No manual operations are
allowed. To fully utilize the capability of AI recommendations, providing such
an API will help UBS make the whole workflow more smooth and increase Kyligence
usage. Meanwhile, the maintenance effort and total infra cost can be
significantly reduced also.
