NAME¶
mysqlslap - load emulation clientSYNOPSIS¶
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]
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
mysqlslap --concurrency=5 --iterations=20 \ --number-int-cols=2 --number-char-cols=3 \ --auto-generate-sql
mysqlslap --concurrency=5 \ --iterations=5 --query=query.sql --create=create.sql \ --delimiter=";"
•--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
Specify how many secondary indexes to add to automatically 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.
•--commit=N
How many statements to execute before committing. The default is 0 (no commits
are done).
•--compress, -C
Compress all information sent between the client and the server if both support
compression.
•--concurrency=N, -c
N
The number of clients to simulate when issuing the SELECT 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
Set filename as the file to read default options from after the
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

•--socket=path, -S

name of the named pipe to use.
