Ask about the progress of iceberg data compaction development

[Li,Ang(AIDP)]

Hi all:
I am very interested in the proposal of iceberg data compaction and I have read 
the 
document<https://docs.google.com/document/d/1aXo1VzuXxSuqcTzMLSQdnivMVgtLExgDWUFMvWeXRxc/edit#heading=h.41vc5dxcib1o>.
   I think the proposal idea in the document is great!
   I want to inquire about the current progress of the program.
I am very interested and want to join the development of the program.
                                                                                
                                                Best wishes
