> In KYLIN-1851, we reduce the peek memory usage of the dictionary-building
> procedure by splitting a single Trie tree structure to Trie forest. But there
> still exist a bottleneck that all the dictionaries are built in Kylin client.
> In this issue, we want to use multi reducers to build different dictionaries
> locally and concurrently，which can further reduce the peek memory usage as
> well as speed up the dictionary-building procedure.
