I have 2 suggestions:

1. prop cannot support inline expression.
2. using random as snowflake's work_id is not correct. work_id should be a static value of one node.

So I just close this issue and label it as invalid.

...,but RANDOM in SNOWFLAKE is very useful ,This makes deployment easier and simpler。
YAML can use it，XML should use it。In this way, SHARDING-JDBC is the unified and consistent usage.
