consultation for kylin2.0 parameters
Hi ,all:
I have a question about “kylin.dictionary.growing-enabled”, Can you tell me the function of this parameter?
Thanks!

When turned on, kylin tries to grow an existing dictionary instead of
creating new dictionaries. However, as tested, this hurts performance in
some cases, and because memory is usually sufficient to load many
dictionaries, this flag is off by default.
