n3nash edited a comment on issue #1278: [HUDI-573] Refactoring getter to avoid double extrametadata
in json representation of HoodieCommitMetadata
URL: https://github.com/apache/incubator-hudi/pull/1278#issuecomment-578251544
 
 
   When ObjectMapper converts a POJO to json string, it generates getters for the variables
in the class as well as pulls the existing getters in the class after which it will stitch
together the object to string. In HoodieCommitMetadata, there is a variable extraMetadataMap
and also a getter method getExtraMetadata(). During serialization, there will be 2 object
to string conversions 1) getExtraMetadata() 2) getExtraMetadataMap() (created by ObjectMapper)
that results in 2 copies of the same data in JSON.
