PostgreSQL 10 vs MySQL 8Roadmap
• EnterpriseDB– Parallelism
• Parallel Hash• Parallel Bitmap Heap Scan• Gather Merge• Parallel Index Scan• parallel VACUUM
– Partitioning– Foreign Data Wrappers– Replication– Vertical Scalability– Performance– SQL Features
• Oracle– Data Dictionary
• MyISAM is Dead !!
– Account management• Using Roles
– InnoDB enhancements• AUTO_INCREMENT• shared temporary tablespace,
Ibtmp1• Dynamic
innodb_deadlock_detect
– JSON enhancements.– remove ST_ and MBR
functions– Remove mysql_install_db– InnoDB no longer supports
compressed temporary tables– Remove innodb_support_xa
