Summary: More Robust Global Dictionary
Key: KYLIN-2192
URL: https://issues.apache.org/jira/browse/KYLIN-2192
Project: Kylin
Issue Type: Improvement
Components: Job Engine
Affects Versions: v1.5.4.1
Reporter: Yerui Sun
Assignee: Yerui Sun
Fix For: v1.6.0
Global dictionary have been released over 2 months, I've received some
feedbacks and bug reports. Here's the patch to make global dictionary more
robust, including some functional improvements.
* Break through 255 bytes limitation for value, but still recommend value
length less than 8K, avoiding stack overflow error;
* Fix 'Value not exists' or stack overflow error when dict size is larger than
1GB, the root cause is similar with KYLIN-1834; A check tool also provided for
check corrupted or not of existing dict data;
* Support parallel dictionary building in one job server, used for parallel
segments building;
