InnoDB is not your default storage engine,
you can determine if your database server or applications work
InnoDB by restarting the server
defined on the command line or with
defined in the
[mysqld] section of your MySQL
server option file.
Since changing the default storage engine only affects new tables
as they are created, run all your application installation and
setup steps to confirm that everything installs properly. Then
exercise all the application features to make sure all the data
loading, editing, and querying features work. If a table relies on
a feature that is specific to another storage engine, you will
receive an error; add the
clause to the
statement to avoid the error.
If you did not make a deliberate decision about the storage
engine, and you want to preview how certain tables work when
InnoDB, issue the command
table_name ENGINE=InnoDB; for each table. Or, to run
test queries and other statements without disturbing the original
table, make a copy:
CREATE TABLE InnoDB_Table (...) ENGINE=InnoDB AS SELECT * FROM other_engine_table;
To assess performance with a full application under a realistic workload, install the latest MySQL server and run benchmarks.
Test the full application lifecycle, from installation, through heavy usage, and server restart. Kill the server process while the database is busy to simulate a power failure, and verify that the data is recovered successfully when you restart the server.
Test any replication configurations, especially if you use different MySQL versions and options on the source server and replicas.
