Databases
The app has 21 engine choices. Some share a protocol adapter. A connection path doesn’t certify every server version or hosted provider.

Limits
Results are limited to 1,000 rows and 16 MiB. Most engines also limit individual cells to 4 MiB. PostgreSQL and MySQL/MariaDB use the overall result limit. Database drivers can allocate data before the app checks these display limits.
SSH tunnels, interactive cloud sign-in, cluster administration and bulk database transfer aren’t built in. BigQuery starts with a 1 GiB maximum-billed-bytes limit per query; other provider charges may still apply.
