Modified DBT-1 for Postgres-XC test and evaluation This folder contains DBT-1 material to test and evaluate Postgres-XC. The following modifications were made. 1. PostgreSQL interface was changed from ODBC to libpq. It allows much more workload to apply. 2. Added housekeeping feature of ORDER table. Original DBT-1 did not maintain old ORDER table. So performance drop was observed when the benchmark is done for a long period (days to weeks). The main reason is infinite growth of ORDER table. 3. Table design change. Table design was changed to utilize Postgres-XC's parallel execution feature and to avoid cross-node operations. For details of the change, please refer to Postgres-XC's architecture document. The original DBT-1 repository will be found at git://osdldbt.git.sourceforge.net/gitroot/osdldbt/osdldbt And the summary will be at http://osdldbt.git.sourceforge.net/git/gitweb.cgi?p=osdldbt/dbt1;a=summary Postgres-XC development team appreciates Mr.Mark Wong who kindly approved to add this material to Postgres-XC releases. We also appreciate if anybody take a look at these modifications and include some of them into the original DBT-1 repository. Postgres-XC development team
