Where can I obtain complete documentation for MySQL storage
See Chapter 16, Alternative Storage Engines. That chapter contains
information about all MySQL storage engines except for the
InnoDB storage engine and the
NDB storage engine (used for MySQL
InnoDB is covered in
Chapter 15, The InnoDB Storage Engine.
NDB is covered in
Chapter 23, MySQL NDB Cluster 8.2.
Are there any new storage engines in MySQL 8.2?
InnoDB is the default storage engine for
new tables. See Section 15.1, “Introduction to InnoDB” for
Have any storage engines been removed in MySQL 8.2?
PARTITION storage engine plugin which
provided partitioning support is replaced by a native
partitioning handler. As part of this change, the server can no
longer be built using
partition is also no longer displayed in the
SHOW PLUGINS, or shown
In order to support partitioning of a given table, the storage
engine used for the table must now provide its own
(“native”) partitioning handler.
InnoDB is the only storage engine
supported in MySQL 8.0 that includes a native partitioning
handler. An attempt to create partitioned tables in MySQL 8.0
using any other storage engine fails. (The
NDB storage engine used by MySQL
Cluster also provides its own partitioning handler, but is
currently not supported by MySQL 8.0.)
Can I prevent the use of a particular storage engine?
configuration option defines which storage engines cannot be
used to create tables or tablespaces. By default,
empty (no engines disabled), but it can be set to a
comma-separated list of one or more engines.
Is there an advantage to using the
storage engine exclusively, as opposed to a combination of
InnoDB and non-
InnoDB tables exclusively can
simplify backup and recovery operations. MySQL Enterprise Backup
does a hot backup of all
tables that use the
InnoDB storage engine.
For tables using
MyISAM or other
InnoDB storage engines, it does a
“warm” backup, where the database continues to run,
but those tables cannot be modified while being backed up. See
Section 30.2, “MySQL Enterprise Backup Overview”.
What are the unique benefits of the
ARCHIVE storage engine stores large
amounts of data without indexes; it has a small footprint, and
performs selects using table scans. See
Section 16.5, “The ARCHIVE Storage Engine”, for details.
