For dump file reloading, faster secondary index creation for
InnoDB
tables by adding indexes after rows are inserted
.RE
.PP
\fBmysqlpump\fR
requires at least the
SELECT
privilege for dumped tables,
SHOW VIEW
for dumped views,
TRIGGER
for dumped triggers, and
LOCK TABLES
if the
\fB\-\-single\-transaction\fR
option is not used\&. The
SELECT
privilege on the
mysql
system database is required to dump user definitions\&. Certain options might require other privileges as noted in the option descriptions\&.
.PP
To reload a dump file, you must have the privileges required to execute the statements that it contains, such as the appropriate
CREATE
privileges for objects created by those statements\&.

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\ \&10.4, \(lqConnection Character Sets and Collations\(rq), so the dump file does not load 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 \{\

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\&.

\fBmysqlpump\fR
supports, issue the command
\fBmysqlpump \-\-help\fR\&.

\fBmysqlpump\fR
supports the following options, which can be specified on the command line or in the
[mysqlpump]

[client]
groups of an option file\&. (Prior to MySQL 5\&.7\&.30,
\fBmysqlpump\fR
read the
[mysql_dump]
group rather than
[mysqlpump]\&. As of 5\&.7\&.30,
[mysql_dump]
is still accepted but is deprecated\&.) For information about option files used by MySQL programs, see

\fB\-\-compress\-output=\fR\fB\fIalgorithm\fR\fR
By default,
\fBmysqlpump\fR
does not compress output\&. This option specifies output compression using the specified algorithm\&. Permitted algorithms are
LZ4
and
ZLIB\&.
.sp
To uncompress compressed output, you must have an appropriate utility\&. If the system commands
\fBlz4\fR
and
\fBopenssl zlib\fR
are not available, as of MySQL 5\&.7\&.10, MySQL distributions include
\fBlz4_decompress\fR
and
\fBzlib_decompress\fR
utilities that can be used to decompress
\fBmysqlpump\fR
output that was compressed using the
\fB\-\-compress\-output=LZ4\fR
and
\fB\-\-compress\-output=ZLIB\fR
options\&. For more information, see
lz4_decompress(1), and
zlib_decompress(1)\&.
.sp
Alternatives include the
\fBlz4\fR
and
\fBopenssl\fR
commands, if they are installed on your system\&. For example,
\fBlz4\fR
can uncompress
LZ4
output:
.sp
.if n \{\
.RS 4
.\}
.nf
lz4 \-d \fIinput_file output_file\fR
.fi
.if n \{\
.RE
.\}
.sp
ZLIB
output can be uncompresed like this:
.sp
.if n \{\
.RS 4

.nf
openssl zlib \-d < \fIinput_file\fR > \fIoutput_file\fR

\fB\-\-databases\fR,

Normally,
\fBmysqlpump\fR
treats the first name argument on the command line as a database name and any following names as table names\&. With this option, it treats all name arguments as database names\&.
CREATE DATABASE
statements are included in the output before each new database\&.

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

The

\fIdb_list\fR
is a list of comma\-separated database names\&. If the option argument begins with
\fIN\fR:, the queue uses
\fIN\fR
threads\&. Otherwise, the
\fB\-\-default\-parallelism\fR

option create multiple queues\&.

Names in the database list are permitted to contain the same

.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\&.
