It will be hard for the developers of Derby to improve the performance to a reasonable level.
A few problems have been identified: leaving autocommit on is a problem for Derby.
If it is switched off during the whole test, the results are about 20% better for Derby.
Derby does not call <code>FileDescriptor.sync() / FileChannel.force(..)</code> on each commit.
Derby calls <code>FileChannel.force(false)</code>, but only twice per log file (not on each commit).
Disabling this call improves performance for Derby by about 2%.
Unlike H2, Derby does not call <code>FileDescriptor.sync()</code> on each checkpoint.
Derby supports a testing mode (system property <code>derby.system.durability=test</code>)
where durability is disabled. According to the documentation, this setting should be used for testing only,
as the database may not recover after a crash. Enabling this setting improves performance

Nested Outer Joins
TIMESTAMPDIFF
-----------------
Example:
Test cases:
select timestampdiff(year, '2000-01-01', '2001-01-01');
select timestampdiff(year, '2000-03-01', '2001-03-01');
select timestampdiff(day, '2000-03-01', '2001-03-01');
select timestampdiff(year, '2000-02-29', '2001-02-28');
select timestampdiff(day, '2000-02-29', '2001-02-28');
select timestampdiff(month, '2000-02-29', '2001-02-28');
select timestampadd(year, 1, '2000-02-29');
create table a(x int);
create table b(x int);
create table c(x int, y int);
insert into a values(1);
insert into a values(2);
insert into b values(3);
insert into c values(1, 3);
insert into c values(4, 5);
select * from a left outer join (b left outer join c on b.x = c.y) on a.x = c.x;
explain select * from a left outer join (b left outer join c on b.x = c.y) on a.x = c.x;
drop table a;
drop table b;
drop table c;
The following doesn't work correctly:
TableFilter,
private void mapAndAddFilter(Expression on) throws SQLException {
on.mapColumns(this, 0);
if (join == null || on.isEverything(ExpressionVisitor.RESOLVED)) {
addFilterCondition(on, true);
on.createIndexConditions(session, this);
}
if (join != null) {
join.mapAndAddFilter(on);
}
}
drop table base;
drop table a;
drop table b;
create table a( pk integer, val varchar(255) );
create table b( pk integer, val varchar(255) );
create table base( pk integer, deleted integer );
insert into base values ( 1, 0 );
insert into base values ( 2, 1 );
insert into base values ( 3, 0 );
insert into a values ( 1, 'a' );
insert into b values ( 2, 'a' );
insert into b values ( 3, 'a' );
select a.pk, a_base.pk, b.pk, b_base.pk from a inner join base a_base
on a.pk = a_base.pk left outer join
( b inner join base b_base on b.pk = b_base.pk and b_base.deleted = 0 ) ;
