1 MySQL and PostgreSQL Evaluation Past tests, tools and highlights António Amorim, Carlos Jesus. CU1 - First Database Testing Meeting, 20/Nov/08

2 Test objectives Past studies evaluated the architecture and performance of MySQL Cluster and PostgreSQL solutions for the Gaia Databases. MySQL Cluster: –MySQL-Cluster Poor performance Redundancy benefits –PostgreSQL Sends 2x more data than MySQL Poor Bytea performance Network load(400K objects) PostgreSQL: 2072M MYSQL:1050 Mb ORACLE-XE: 520 Mb António Amorim, Carlos Jesus. CU1 - First Database Testing Meeting, 20/Nov/08

3 Single MySQL Server In order to pinpoint bottlenecks associated with MySQL, a series of basic tests were performed, these new tests made use of the available MDBExtractorIngestor package. Control and Monitor: Available at the local infrastructure was the SMS (Supervisor Monitor Scheduler) batch system, we deployed in one node the database and in another the Ingestor. At the local infrastructure was available the SMS (Supervisor Monitor Scheduler) batch system. The tests basic 2 node client server model the nodes where as following: Hardware setup António Amorim, Carlos Jesus. CU1 - First Database Testing Meeting, 20/Nov/08
