Please refer to Built-in Sharding Algorithm List and Built-in Key Generate Algorithm List for more details about type of algorithm.

Attention

Inline expression identifier can use ${...} or $->{...}, but ${...} is conflict with spring placeholder of properties, so use $->{...} on spring environment is better.
