New buffer replacement strategy that improves caching (Jan)
|
||||
</para>
|
||||
<para>
|
||||
Prior releases use a least-recently-used (LRU) cache to keep
|
||||
recently referenced pages in the cache. Unfortunately, the cache
|
||||
did not consider the number of times a specific cache entry was
|
||||
accessed. Large table scans could force out useful cache pages.
|
||||
The new cache uses four separate cache areas to track most
|
||||
recently used and most frequently used cache pages to dynamically
|
||||
optimize their replacement based on the work load. This should
|
||||
lead to much more efficient use of the shared buffer cache.
|
||||
Administrators who have tested shared buffer sizes in the past
|
||||
should retest with this new cache replacement policy.

Add subprocess to write dirty buffers periodically to reduce checkpoint writes (Jan)
|
||||
</para>
|
||||
<para>
|
||||
In previous releases, the checkpoint process, which runs every few
|
||||
minutes, would write all dirty buffers to the operating system
|
||||
buffer cache then flush all operating system dirty buffers to
|
||||
disk. This often resulted in a periodic spike in disk usage that
|
||||
hurt performance. The new code uses a background writer to trickle
|
||||
disk writes at a steady pace so checkpoints have far fewer dirty
|
||||
pages to write to disk. This should improve performance and
|
||||
minimize performance degradation during checkpoints.

Optimizer improvements and subquery fixes (Tom)

</para>

<para>
|
||||
It is difficult to explain all the optimizer improvements that go
|
||||
into a release like this. They involve complex adjustments to the
|
||||
logic used to select indexes, join methods, and join order. They
|
||||
are difficult to explain, but the result is that the optimizer
|
||||
make quicker and better choices in how to execute queries,
|
||||
resulting in improved performance. The close relationship between
|
||||
our developers and users reporting problems allows us to make
|
||||
rapid and complex optimizer improvements that would be very
|
||||
difficult for lose-source companies to emulate.

Implement dollar quoting to simplify single-quote usage (Andrew)

In previous releases, because single quotes had to be used to

mechanisms. With this release we add the ability to use "dollar

quoting" to quote a block of text that eliminates the awkwardness

of single quotes used inside the function. Dollar quoting can
