The

A dump made using PowerShell on Windows with output redirection creates a file that has UTF\-16 encoding:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] > dump\&.sql
.fi
.if n \{\
.RE
.\}
.PP
However, UTF\-16 is not permitted as a connection character set (see
Section\ \&12.4, \(lqConnection Character Sets and Collations\(rq), so the dump file cannot be loaded correctly\&. To work around this issue, use the
\fB\-\-result\-file\fR
option, which creates the output in ASCII format:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] \-\-result\-file=dump\&.sql
.fi
.if n \{\
.RE

.sp .5v

.PP
By default,
\fBmysqlpump\fR
dumps all databases (with certain exceptions noted in
mysqlpump Restrictions)\&. To specify this behavior explicitly, use the
\fB\-\-all\-databases\fR
option:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-all\-databases
.fi
.if n \{\
.RE
.\}
.PP
To dump a single database, or certain tables within that database, name the database on the command line, optionally followed by table names:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \fIdb_name\fR
mysqlpump \fIdb_name tbl_name1 tbl_name2 \&.\&.\&.\fR
.fi
.if n \{\
.RE
.\}
.PP
To treat all name arguments as database names, use the
\fB\-\-databases\fR
option:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-databases \fIdb_name1 db_name2\fR \&.\&.\&.
.fi
.if n \{\
.RE
.\}
.PP
By default,
\fBmysqlpump\fR
does not dump user account definitions, even if you dump the
mysql
system database that contains the grant tables\&. To dump grant table contents as logical definitions in the form of
CREATE USER
and
GRANT
statements, use the
\fB\-\-users\fR
option and suppress all database dumping:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-exclude\-databases=% \-\-users
.fi
.if n \{\
.RE
.\}
.PP
In the preceding command,
%
is a wildcard that matches all database names for the
\fB\-\-exclude\-databases\fR
option\&.
.PP
\fBmysqlpump\fR
supports several options for including or excluding databases, tables, stored programs, and user definitions\&. See
mysqlpump Object Selection\&.
.PP
To reload a dump file, execute the statements that it contains\&. For example, use the
\fBmysql\fR
client:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump [options] > dump\&.sql
mysql < dump\&.sql
.fi
.if n \{\

The following discussion provides additional
\fBmysqlpump\fR
usage examples\&.

To see a list of the options
\fBmysqlpump\fR
supports, issue the command
\fBmysqlpump \-\-help\fR\&.
mysqlpump Option Summary
.PP
\fBmysqlpump\fR
supports the following options, which can be specified on the command line or in the
[mysqlpump]

[client]

\fBmysqlpump\fR
read the

[mysqlpump]\&. As of 8\&.0\&.20,
[mysql_dump]

If multiple databases are being dumped, it is possible to name tables, triggers, and routines in a specific database by qualifying the object names with the database name\&. The following command dumps databases

.sp

.el \{\

The

\fBmysqlpump\fR

.sp

mysqlpump Parallel Processing

\fBmysqlpump\fR
can use parallelism to achieve concurrent processing\&. You can select concurrency between databases (to dump multiple databases simultaneously) and within databases (to dump multiple objects from a given database simultaneously)\&.
.PP
By default,
\fBmysqlpump\fR
sets up one queue with two threads\&. You can create additional queues and control the number of threads assigned to each one, including the default queue:

\fIdb_list\fR

\fIN\fR
threads\&. Otherwise, the
\fB\-\-default\-parallelism\fR

.RE
.PP
\fBmysqlpump\fR
uses the default queue for processing any databases not named explicitly with a
\fB\-\-parallel\-schemas\fR
option, and for dumping user definitions if command options select them\&.
.PP
In general, with multiple queues,
\fBmysqlpump\fR
uses parallelism between the sets of databases processed by the queues, to dump multiple databases simultaneously\&. For a queue that uses multiple threads,
\fBmysqlpump\fR
uses parallelism within databases, to dump multiple objects from a given database simultaneously\&. Exceptions can occur; for example,
\fBmysqlpump\fR
may block queues while it obtains from the server lists of objects in databases\&.
.PP
With parallelism enabled, it is possible for output from different databases to be interleaved\&. For example,
INSERT
statements from multiple tables dumped in parallel can be interleaved; the statements are not written in any particular order\&. This does not affect reloading because output statements qualify object names with database names or are preceded by
USE
statements as required\&.
.PP
The granularity for parallelism is a single database object\&. For example, a single table cannot be dumped in parallel using multiple threads\&.
.PP
Examples:
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-parallel\-schemas=db1,db2 \-\-parallel\-schemas=db3
.fi
.if n \{\
.RE
.\}
.PP
\fBmysqlpump\fR
sets up a queue to process
db1
and
db2, another queue to process
db3, and a default queue to process all other databases\&. All queues use two threads\&.
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-parallel\-schemas=db1,db2 \-\-parallel\-schemas=db3
          \-\-default\-parallelism=4
.fi
.if n \{\
.RE
.\}
.PP
This is the same as the previous example except that all queues use four threads\&.
.sp
.if n \{\
.RS 4
.\}
.nf
mysqlpump \-\-parallel\-schemas=5:db1,db2 \-\-parallel\-schemas=3:db3
.fi
.if n \{\
.RE
.\}
.PP
The queue for
db1
and
db2
uses five threads, the queue for
db3
uses three threads, and the default queue uses the default of two threads\&.
.PP
As a special case, with
\fB\-\-default\-parallelism=0\fR
and no
\fB\-\-parallel\-schemas\fR
options,
\fBmysqlpump\fR
runs as a single\-threaded process and creates no queues\&.
mysqlpump Restrictions
.PP
\fBmysqlpump\fR
does not dump the
performance_schema,
ndbinfo, or
sys

\fB\-\-databases\fR
or
\fB\-\-include\-databases\fR
option\&.
.PP
\fBmysqlpump\fR
does not dump the
INFORMATION_SCHEMA
schema\&.
.PP
\fBmysqlpump\fR
does not dump
InnoDB
CREATE TABLESPACE

.PP
\fBmysqlpump\fR
dumps user accounts in logical form using
CREATE USER

GRANT
statements (for example, when you use the
\fB\-\-include\-users\fR

\fB\-\-users\fR

mysql
system database do not by default include the grant tables that contain user definitions:
user,
db,
tables_priv,

procs_priv, or
