Populate both tables so that an indexed column of the cached table has a foreign key reference to the main table. This database can be used to demonstrate efficient queries to retrieve the data from the cached table. 1.7.1 insert timings for 100000 rows, cache scale 12: simple table, no extra index: 52 s with index on lastname only: 56 s with index on zip only: 211 s foreign key, referential_integrity true: 216 s The above have improved a lot in 1.7.2 This test now incorporates the defunct TestTextTables author:    fredt@users version:    1.8.0 since:    1.7.0 Field Summary  boolean addForeignKey       int bigops       int bigrows       Connection cConnection       int cacheScale       int cacheSizeScale       boolean createTempTable       boolean deleteWhileInsert       int deleteWhileInsertInterval      protected  boolean filedb      protected  String filepath       boolean indexLastName       boolean indexZip       String logType       boolean multikeytable       boolean nioMode       String password       boolean refIntegrity       boolean reportProgress       Statement sStatement      protected  boolean shutdown       int smallops       int smallrows       String tableType      protected  String url       String user       int writeDelay       FileWriter writer      Method Summary protected  void checkResults()      static  void deleteDatabase(String path)       void deleteTest()       void deleteZipTable()      public static  void main(String[] argv)       int nextIntRandom(Random r, int range)       void selectID()       void selectZip()       void selectZipTable()      protected  void setUp()       void storeResult(String description, int count, long time, long rate)      protected  void tearDown()      public  void testFillUp()       void updateID()       void updateIDLinear()      Field Detail addForeignKey boolean addForeignKey(Code) bigops int bigops(Code) bigrows int bigrows(Code) cConnection Connection cConnection(Code) cacheScale int cacheScale(Code) cacheSizeScale int cacheSizeScale(Code) createTempTable boolean createTempTable(Code) deleteWhileInsert boolean deleteWhileInsert(Code) deleteWhileInsertInterval int deleteWhileInsertInterval(Code) filedb protected boolean filedb(Code) filepath protected String filepath(Code) indexLastName boolean indexLastName(Code) indexZip boolean indexZip(Code) logType String logType(Code) multikeytable boolean multikeytable(Code) nioMode boolean nioMode(Code) password String password(Code) refIntegrity boolean refIntegrity(Code) reportProgress boolean reportProgress(Code) sStatement Statement sStatement(Code) shutdown protected boolean shutdown(Code) smallops int smallops(Code) smallrows int smallrows(Code) tableType String tableType(Code) url protected String url(Code) user String user(Code) writeDelay int writeDelay(Code) writer FileWriter writer(Code) Method Detail checkResults protected void checkResults()(Code) deleteDatabase static void deleteDatabase(String path)(Code) deleteTest void deleteTest()(Code) deleteZipTable void deleteZipTable()(Code) main public static void main(String[] argv)(Code) nextIntRandom int nextIntRandom(Random r, int range)(Code) selectID void selectID()(Code) selectZip void selectZip()(Code) selectZipTable void selectZipTable()(Code) setUp protected void setUp()(Code) storeResult void storeResult(String description, int count, long time, long rate)(Code) tearDown protected void tearDown()(Code) testFillUp public void testFillUp()(Code) Fill up the cache updateID void updateID()(Code) updateIDLinear void updateIDLinear()(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
