NAME
       mysqlslap - load emulation client

SYNOPSIS
       mysqlslap [options]

DESCRIPTION
       mysqlslap is a diagnostic program designed to emulate client load for a
       MariaDB server and to report the timing of each stage. It works as if
       multiple clients are accessing the server.

       Invoke mysqlslap like this:

	   shell> mysqlslap [options]

       Some options such as --create or --query enable you to specify a string
       containing an SQL statement or a file containing statements. If you
       specify a file, by default it must contain one statement per line.
       (That is, the implicit statement delimiter is the newline character.)
       Use the --delimiter option to specify a different delimiter, which
       enables you to specify statements that span multiple lines or place
       multiple statements on a single line. You cannot include comments in a
       file; mysqlslap does not understand them.

       mysqlslap runs in three stages:

	1. Create schema, table, and optionally any stored programs or data
	   you want to using for the test. This stage uses a single client
	   connection.

	2. Run the load test. This stage can use many client connections.

	3. Clean up (disconnect, drop table if specified). This stage uses a
	   single client connection.

       Examples:

       Supply your own create and query SQL statements, with 50 clients
       querying and 200 selects for each:

	   mysqlslap --delimiter=";" \
	     --create="CREATE TABLE a (b int);INSERT INTO a VALUES (23)" \
	     --query="SELECT * FROM a" --concurrency=50 --iterations=200

       Let mysqlslap build the query SQL statement with a table of two INT
       columns and three VARCHAR columns. Use five clients querying 20 times
       each. Do not create the table or insert the data (that is, use the
       previous test´s schema and data):

	   mysqlslap --concurrency=5 --iterations=20 \
	     --number-int-cols=2 --number-char-cols=3 \
	     --auto-generate-sql

       Tell the program to load the create, insert, and query SQL statements
       from the specified files, where the create.sql file has multiple table
       creation statements delimited by ´;´ and multiple insert statements
       delimited by ´;´. The --query file will have multiple queries delimited
       by ´;´. Run all the load statements, then run all the queries in the
       query file with five clients (five times each):

	   mysqlslap --concurrency=5 \
	     --iterations=5 --query=query.sql --create=create.sql \
	     --delimiter=";"

       mysqlslap supports the following options, which can be specified on the
       command line or in the [mysqlslap] and [client] option file groups.
       mysqlslap also supports the options for processing option files.

       ·   --help, -?

	   Display a help message and exit.

       ·   --auto-generate-sql, -a

	   Generate SQL statements automatically when they are not supplied in
	   files or via command options.

       ·   --auto-generate-sql-add-autoincrement

	   Add an AUTO_INCREMENT column to automatically generated tables.

       ·   --auto-generate-sql-execute-number=N

	   Specify how many queries to generate automatically.

       ·   --auto-generate-sql-guid-primary

	   Add a GUID-based primary key to automatically generated tables.

       ·   --auto-generate-sql-load-type=type

	   Specify the test load type. The allowable values are read (scan
	   tables), write (insert into tables), key (read primary keys),
	   update (update primary keys), or mixed (half inserts, half scanning
	   selects). The default is mixed.

       ·   --auto-generate-sql-secondary-indexes=N

	   generated tables. By default, none are added.

       ·   --auto-generate-sql-unique-query-number=N

	   How many different queries to generate for automatic tests. For
	   example, if you run a key test that performs 1000 selects, you can
	   use this option with a value of 1000 to run 1000 unique queries, or
	   with a value of 50 to perform 50 different selects. The default is
	   10.

       ·   --auto-generate-sql-unique-write-number=N

	   How many different queries to generate for
	   --auto-generate-sql-write-number. The default is 10.

       ·   --auto-generate-sql-write-number=N

	   How many row inserts to perform on each thread. The default is 100.

	   statement.

       ·   --create=value

	   The file or string containing the statement to use for creating the
	   table.

       ·   --create-schema=value

	   The schema in which to run the tests.

       ·   --csv[=file_name]

	   Generate output in comma-separated values format. The output goes
	   to the named file, or to the standard output if no file is given.

       ·   --debug[=debug_options], -# [debug_options]

	   Write a debugging log. A typical debug_options string is
	   ´d:t:o,file_name´. The default is ´d:t:o,/tmp/mysqlslap.trace´.

       ·   --debug-check

	   Print some debugging information when the program exits.

       ·   --debug-info, -T

	   Print debugging information and memory and CPU usage statistics
	   when the program exits.

       ·   --default-auth=name

	   Default authentication client-side plugin to use.

       ·   --defaults-extra-file=filename

	   global defaults files has been read.	 Must be given as first
	   option.

       ·   --defaults-file=filename

	   Set filename as the file to read default options from, override
	   global defaults files.  Must be given as first option.

       ·   --delimiter=str, -F str

	   The delimiter to use in SQL statements supplied in files or via
	   command options.

       ·   --detach=N

	   Detach (close and reopen) each connection after each N statements.
	   The default is 0 (connections are not detached).

       ·   --engine=engine_name, -e engine_name

	   Comma separated list of storage engines to use for creating the
	   table. The test is run for each engine. You can also specify an
	   option for an engine after a colon, for example
	   memory:max_row=2300.

       ·   --host=host_name, -h host_name

	   Connect to the MariaDB server on the given host.

       ·   --init-command=str

	   SQL Command to execute when connecting to MariaDB server. Will
	   automatically be re-executed when reconnecting.

       ·   --iterations=N, -i N

	   The number of times to run the tests.

       ·   --no-defaults

	   Do not read default options from any option file. This must be
	   given as the first argument.

       ·   --no-drop

	   Do not drop any schema created during the test after the test is
	   complete.

       ·   --number-char-cols=N, -x N

	   The number of VARCHAR columns to use if --auto-generate-sql is
	   specified.

       ·   --number-int-cols=N, -y N

	   The number of INT columns to use if --auto-generate-sql is
	   specified.

       ·   --number-of-queries=N

	   Limit each client to approximately this many queries. Query
	   counting takes into account the statement delimiter. For example,
	   if you invoke mysqlslap as follows, the ; delimiter is recognized
	   so that each instance of the query string counts as two queries. As
	   a result, 5 rows (not 10) are inserted.

	       shell> mysqlslap --delimiter=";" --number-of-queries=10
			--query="use test;insert into t values(null)"

       ·   --only-print

	   Do not connect to databases.	 mysqlslap only prints what it would
	   have done.

       ·   --password[=password], -p[password]

	   The password to use when connecting to the server. If you use the
	   short option form (-p), you cannot have a space between the option
	   and the password. If you omit the password value following the
	   --password or -p option on the command line, mysqlslap prompts for
	   one.

	   Specifying a password on the command line should be considered
	   insecure. You can use an option file to avoid giving the password
	   on the command line.

       ·   --pipe, -W

	   On Windows, connect to the server via a named pipe. This option
	   applies only if the server supports named-pipe connections.

       ·   --plugin-dir=dir_name

	   Directory for client-side plugins.

       ·   --port=port_num, -P port_num

	   The TCP/IP port number to use for the connection.

       ·   --post-query=value

	   The file or string containing the statement to execute after the
	   tests have completed. This execution is not counted for timing
	   purposes.

       ·   --post-system=str

	   The string to execute via system() after the tests have completed.
	   This execution is not counted for timing purposes.

       ·   --pre-query=value

	   The file or string containing the statement to execute before
	   running the tests. This execution is not counted for timing
	   purposes.

       ·   --pre-system=str

	   The string to execute via system() before running the tests. This
	   execution is not counted for timing purposes.

       ·   --print-defaults

	   Print the program argument list and exit.  This must be given as
	   the first argument.

       ·   --protocol={TCP|SOCKET|PIPE|MEMORY}

	   The connection protocol to use for connecting to the server. It is
	   useful when the other connection parameters normally would cause a
	   protocol to be used other than the one you want.

       ·   --query=value, -q value

	   The file or string containing the SELECT statement to use for
	   retrieving data.

       ·   --shared-memory-base-name=name

	   On Windows, the shared-memory name to use, for connections made via
	   shared memory to a local server. This option applies only if the
	   server supports shared-memory connections.

       ·   --silent, -s

	   Silent mode. No output.

       ·   --socket=path, -S path

	   For connections to localhost, the Unix socket file to use, or, on
	   Windows, the name of the named pipe to use.

	   Enable SSL for connection (automatically enabled with other flags).
	   Disable with --skip-ssl.

       ·   --ssl-ca=name

	   CA file in PEM format (check OpenSSL docs, implies --ssl).

       ·   --ssl-capath=name

	   CA directory (check OpenSSL docs, implies --ssl).

	   Certificate revocation list path (check OpenSSL docs, implies
	   --ssl).

       ·   --ssl-verify-server-cert

	   Verify server's "Common Name" in its cert against hostname used
	   when connecting. This option is disabled by default.

       ·   --user=user_name, -u user_name

	   The MariaDB user name to use when connecting to the server.

       ·   --verbose, -v

	   Verbose mode. Print more information about what the program does.
