Developer writes GO structures with metadata (field tags & helper methods)
SQL DDL scrips are generated from the GO structures
Connectivity to existing schema is needed to generate alter statements but tool needs to work also without connecitivity (then it generates new schema with tables, UDTs etc.)
Iterations
Iteration 1 - struct -> DDL
Generating new schema (in this iteration there is no need to connect to existing cassandra schema because no alter statments are calulated yet)
Primary Keys
Default mapping for go types to cassandra types
Iteration 2 - struct -> DDL
Indexes
UDTs
customizable mapping of go types to cassandra types using new GO structure field tags
Iteration 3 - diff DDLs
Alter table/type statements
Iteration 4 - integration & doc
showcase how all four tools work together during upgrade procedure (deploying new version of microservice)
describe everything in documentation with example/tutorial
