-Objects test suite
-~~~~~~~~~~~~~~~~~~
-Create 49166 objects in a database and drop the database afterwards.

-3 Further testing scenarios

-
-1 Quick overview
-~~~~~~~~~~~~~~~~
-1.1 What is tested?
-A database with 49166 objects (tables and views) is created. The
-database is dropped afterwards. Only DDL statements are used. No
-data is loaded at all.
-
-1.2 Steps of the test
-- CREATE SCHEMA.
-- Populate 49166 objects.
-- Check the objects with SHOW TABLES.
-- Check the output of one SHOW CREATE TABLE.
-- DROP SCHEMA.
-
-1.3 How to run the test
-Run objects test:
-./mysql-test-run.pl --skip-ndb --suite=objects
-
-If one experiences time out problems, please use
-  --testcase-timeout=3600 --suite-timeout=3600
-
-Run objects test with Falcon storage engine only:
-- Run time. No run time due to crash.
-- Space requirements ~1.3 GB.
-./mysql-test-run.pl --skip-ndb --suite=objects --do-test=objects_falcon
-
-To avoid time out on Falcon storage engine use
-./mysql-test-run.pl --skip-ndb --testcase-timeout=3600 --suite-timeout=3600 \
---suite=objects --do-test=objects_falcon
-
-Run objects test with InnoDB storage engine only.
-- Run time ~100 minutes.
-- Space requirements ~1.5 GB.
-./mysql-test-run.pl --skip-ndb --suite=objects --do-test=objects_innodb
-
-
-2 Detailed overview
-~~~~~~~~~~~~~~~~~~~
-2.1 Background of this test
-The motivation of this test is rooted in the SAP porting project. To
-run SAP specific tests one has to create a small database (~17000 tables
-and views) or depending on the tests to be run a big database (~50000
-tables and views).
-   The SAP porting team tested various storage engines and found out
-that prior to running the SAP tests the loading of the required data
-often lead to problems and crashes in the database server.
-   As the initial data loading for a SAP test is around 5 GB the DDL
-part of the data loading was stripped out. 
-   A successful run of this test can be followed by a R3load test (data
-loading with a SAP tool), to see whether the storage engine can handle
-the rather huge amount of data and to measure the performance while
-loading the data.
-
-2.2 Usage in a given bk tree
-If one wants to test in a give bk tree, lets say 5.1-falcon, one can
-either copy or soft link this suite into the mysql-test/suite/
-folder. We recommend a soft link:
-  ln -s <path_to>/mysql-test-extra-5.1/mysql-test/suite/objects \
-  <path_to>/mysql-5.1-falcon/mysql-test/suite
-
-2.3 What kind of objects?
-Although, the number of 49166 objects sounds huge only tables and
-views are created. Please note, that this test does not create:
-- Stored procedures.
-- Foreign keys.
-- Triggers.
-- Events.
-   This means, that this test suite has a potential for improvement
-by adding further objects like stored procedures, foreign keys,
-triggers, or events.
-
-
-3 Further testing scenarios
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-3.1 Testing the functionality and performance of our INFORMATION_SCHEMA
-Tests on INFORMATION_SCHEMA can be done by disabling the DROP SCHEMA at
-the end of the test by setting the variable $drop_database to 0 (zero):
-  let $drop_database= 0;
-This can be done in the objects_<engine_type>.test file.
-   Performance tests with huge amount of tables and views can be done by
-generating the objects several time in different databases.
-
-3.2 DDL Performance
-The run time of this test can be used as an indicator for DDL performance
-of the engine.
-
-3.3 ALTER TABLE performance
-After object creation an ALTER TABLE <table_name> Engine <other_engine>
-can be done.
