> 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;
