-------------------------------

[~ouyangwuli] Hello!

I'm currently working on a project that involves schema evolution in Postgres. 
I've been thinking about how to best handle it, and I think that if there are 
changes in schema of DataChangeEvent (like renaming columns, adding columns, 
etc), we'll need to re-discover the schema of the table from the source. But 
I'm worried about the speed and performance of the load process after these 
changes. I was wondering how you plan to handle schema evolution, and if you've 
got any tips or tricks up your sleeve.

> PostgreSQL obtains incremental data from the log log parsing, the current 
> parser does not support DDL, but we can deduce the table structure from the 
> schema information, so it is also possible to implement table structure 
> evolution.
