> Reporter: Liu Shaohui
> Assignee: Liu Shaohui
> Priority: Minor

> When the global dict is too large than the spark executor memory, there will be too many dict slice evictions and loads in AppendTrieDictionary, and the build job will be very slow.
> It's better to throw an exception in advance in this case.
