-----------------------------------
Summary: Remove Jackson annotations from POJO classes in Meta
Key: CALCITE-839
URL: https://issues.apache.org/jira/browse/CALCITE-839
Project: Calcite
Issue Type: Bug
Components: avatica
Reporter: Julian Hyde
Assignee: Julian Hyde
The Meta interface contains several POJO classes that represent RPC requests or
responses. Currently a few of those classes have Jackson annotations such as
@JsonCreator, @JsonProperty to help Jackson serialize the POJO to JSON and
de-serialize from JSON to the object.
As [~ndimiduk] pointed out in
http://mail-archives.apache.org/mod_mbox/incubator-calcite-dev/201503.mbox/%3CCANZa=gvkgd+bkj4+ejmuo6ivhs+okgskg1vwdazcy-zijyy...@mail.gmail.com%3E
these annotations are a "code smell" and should be removed. It makes it look
as if Jackson is the only possible transport, which is not the case. We can
continue to use Jackson as a transport, just specify the mappings elsewhere,
not as annotations.
