Package org.epics.archiverappliance.config.persistence

Class MySQLPersistence

java.lang.Object

org.epics.archiverappliance.config.persistence.MySQLPersistence

All Implemented Interfaces:

ConfigPersistence

public class MySQLPersistence
extends Object
implements ConfigPersistence

Persistence layer ontop of MySQL TEXT(blobs) on InnoDB Bear in mind, an untuned mysql server does poorly in terms of performance. At the minimum consider using innodb_flush_log_at_trx_commit=0 if you plan to import large numbers of pvs etc.
