MySQL import silently failing I'm trying to import a large (30GB) SQL file (generated using mysqldump) into an RDS instance MySQL 5.7 database, from an EC2 instance on the same VPC.
It's importing most without a problem, but missing around 5 tables from the end of the dump.
Looking around for related logs in the AWS console I can't really find much of use, all I'm seeing is this:

----------------------- END OF LOG ----------------------

I'm not really sure where to start looking without any logs. Only thing I can think of is maybe lack of memory, but looking at the stats it still had &quot;some&quot; memory left on the RDS instance while it was importing.
When I check the file the CREATE TABLE statements are definitely there for the missing tables.
Can anyone give any tips on how I can figure out what's going wrong?
Turned out this was just lack of memory on the chosen RDS instance. Increased it to the &quot;medium&quot; instance instead of &quot;micro&quot; and it imported fine at around 10x the speed, with all tables.
