Mariella DI Giacomo (ViaSat) delivers the talk, "MySQL Group Replication vs PostgreSQL Bi-Directional Replication", on DAY 1 of the Percona Live Open Source Database Conference 2019, 5/29, at Austin, TX.

Integrating the most suitable highly available multi-master, non clustered, freely accessible
relational database management system (RDBMS)
solution for large scale environments is a challenging task; it
resembles evaluating marathon champions trained by different olympic coaches.

This presentation will show the analogies and differences of
MySQL Group Replication and PostgreSQL Bi-Directional Replication (BDR),
two freely accessible and highly-available multi master non clustered RDBMS products
that have been successfully employed in large scale environments requiring high availability.

Both scenarios have demonstrated, through validated prototypes, to be successful,
satisfying data integrity, reliability, and scalability
with slightly different strategies and different upcoming pathways.
