Workflow

1. if keepPartition = true backuping partitions
2. Drop database, therefore, do not use a existing database
3. Create database
4. Create tables
5. Restore partitions if keepPartition = true

TODO

• [ ] Doing dryrun pre-deployement on tmp db to validate all ddl
• [ ] Backup partitions in file to manualy restore it if process fail
• [x] Update only tables or db if updated
• [x] Use default config values for all db (output, ...)
• [x] Data catalog support
• [ ] Allow to execute raw sql like add partition

From @PauloCarneiro99 :

• [x] Enable / Disable database or table from sls
• [x] Sequential deployement by default
• [x] Remove previously deployed database if not present

Changelog

v2.0.0

• Removing custom ddl on database
