/*

  Drizzle Slap

  A simple program designed to work as if multiple clients querying the database,

  then reporting the timing of each stage.

  Drizzle slap runs three stages:

  1) Create schema,table, and optionally any SP or data you want to beign

  the test with. (single client)

  2) Load test (many clients)

  3) Cleanup (disconnection, drop table if specified, single client)

  Examples:

  Supply your own create and query SQL statements, with 50 clients

  querying (200 selects for each):

  drizzleslap --delimiter=";" \

  --create="CREATE TABLE A (a int);INSERT INTO A VALUES (23)" \

  --query="SELECT * FROM A" --concurrency=50 --iterations=200

  Let the program build the query SQL statement with a table of two int

  columns, three varchar columns, five clients querying (20 times each),

  don't create the table or insert the data (using the previous test's

  schema and data):

  drizzleslap --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, and then run all the queries in the query file

  with five clients (five times each):

  drizzleslap --concurrency=5 \

  --iterations=5 --query=query.sql --create=create.sql \

  --delimiter=";"

  @todo

  Add language for better tests

  String length for files and those put on the command line are not

  setup to handle binary data.

  More stats

  Break up tests and run them on multiple hosts at once.

  Allow output to be fed into a database directly.
