In accordance with an embodiment, described herein is a system and method for heterogeneous database replication from a remote server, for example a remote database server. A capture process can be registered as a replication slave to the remote server, and configured to receive transaction event data from that server. Transaction log events associated with a modification to the database at the remote server can be processed, and output as change data, in a canonical format output, for use with one or more heterogeneous targets, for example a target database server or message queue. The process enables capture of transaction log events associated with database transactions at a remote server that may be located on a different computer or network, or within an access-restricted environment such as a cloud environment, without the need to create additional copies of its transaction logs.

System and method for heterogeneous database replication from a remote server

Techniques are described herein for simulating triggers in a database. A database server receives a query that targets a database managed by the database server. The database server is registered with a plugin that determines whether the query is a particular type of query. If so, plugin sends a message to an external process that includes features of the query. The database server can also execute the query regardless of whether the particular type of query is detected.

Simulating data definition triggers in a database system

A system and method for transferring data between different types of systems, and in particular uses log-based replication to transfer data between different types of systems. In accordance with an embodiment, the system can be used to perform a one-time or initial copy of the MySQL data from a source database system to a target database system, and/or to replicate the on-going transactions captured from a MySQL database's binary log into one or additional non-MySQL database(s) on a continuous basis, such that the two systems are synchronized for transactions of interest. In accordance with an embodiment, full or partial data changes can be extracted from the MySQL binary log, optionally transformed, skipped or augmented, output or written to a file, and then applied at any of one or more target systems (e.g. another MySQL database, or a non-MySQL database), thereby synchronizing the source and target systems.
