Brian #1: Psycopg 3

• Psycopg folks recommend starting with 3 for new projects
• 2 is still actively maintained, but no new features are planned
  • recommend staying with 2 for legacy projects
• Psycopg 3 project
• 2 vs 3 feature comparison
• A few Psycopg 3 highlights
  • native asyncio support
  • native support for more Python types (such as Enums) and PostgreSQL types (such as multirange)
  • Default server-side parameters binding
  • Allows binary parameters and query results (and text, of course)
  • Pipeline/batch mode support
  • Static typing support

Michael #2: dacite

• via Raymond Peck
• Simple creation of data classes from dictionaries
• Dacite supports following features:
  • nested structures
  • (basic) types checking
  • optional fields (i.e. typing.Optional)
  • unions
  • forward references
  • collections
  • custom type hooks
• It's important to mention that dacite is not a data validation library.
• Type hooks are interesting too.

• list of current and planned features of RIP, the biggest are listed below:
  • Downloading and aggressive caching of PyPI metadata. (done)

Michael #4: Flaky Tests follow up

• by Marwan Sarieddine
