QUESTION
Info: I am using AWS RDS Mysql 5.6.34 (500GB) instance (Without replica, just the master)
Note: Binlog is enabled & set to Row
Target: Modify a column field_1
from enum to tinyint
Extra info: I am using Rails application. So everytime I wanted to add a value to the enum, I need to write a migration. So converting the enum field to tinyint so I can add or delete a enum value without writing a migration using Active Enum
Other info: I also tried LHM but the RDS instance went out of memory at 93%
Database info before running gh-ost:
...ANSWER
Answered 2020-Dec-02 at 06:50I created the mysql DB from a backup of production db.
Production had innodb_file_format
parameter as Barracuda
The new environment had innodb_file_format
parameter as Antelope
The ROW_FORMAT
for the table in production was COMPRESSED
Unfortunately Antelope
db doesn't support ROW_FORMAT
as COMPRESSED
If I had looked more into the details of information_schema, I could have resolved it eatlier!
