[Bizgres-general] Bizgres 0.6 beta available

[Josh Berkus]

Bizgres beta version 0.6 has been released.  Source is available on the 
bizgres home page (http://bizgres.org); binaries 
for Linux and Solaris are available from GreenPlum 
(http://www.greenplum.com/prod_download.html,  as "DeepGreen PostgreSQL": 
it's the same thing as Bizgres).

This version includes the first patches which Bizgres is getting before 
mainstream PostgreSQL.   These first two patches are Alon Goldshuv's batch 
processing improvement for COPY, which improves bulk loading by as much as 
35%.   The second is Simon Riggs' patch allowing disabling of WAL logging 
on "holding tables", as are frequently used for ETL.  Combined, the two 
patches can halve disk I/O costs for ETL operations.  Both of these 
patches have been submitted to PostgreSQL and should be in PostgreSQL 8.1 
or 8.2 (if accepted).

Bizgres is based on PostgreSQL 8.0.2, and includes JDBC, an enhanced 
Java-based bulk loader, a Windows cross-compile, and a unified installer.  
Bizgres is BSD-licensed.  Documentation for this version will is avaible on 
the Bizgres documentation page 
(http://www.bizgres.org/pages.php?pg=documentation).

Bizgres version 0.7, which will include several more significant features 
(such as table partitioning and a performance configuration tool) should 
be out around July 31.  In the meantime, please download, test, and give 
us your feedback!
