Erlang database drivers

 · The erlang postgres driver epgsql is also quite a bit faster than postgrex. Standalone database performance doesn’t matter as much if the drivers don’t cut it. Mysql-otp is fairly new, but hopefully, it will hold www.doorway.ruted Reading Time: 6 mins. This application provides an Erlang interface to communicate with relational SQL-databases. It is built on top of Microsofts ODBC interface and therefore requires that you have an ODBC driver to the database that you want to connect to. Databases. If you need to access a relational database such as sqlserver, mysql, postgres, oracle, cybase etc. from your erlang application using the Erlang ODBC interface is a good way to go about it. The Erlang ODBC application should work for any relational database that has an ODBC driver. But currently it is only regularly tested for sqlserver and postgres.

The db_driver is a high performance database driver based on the Erlang linked-in driver. It uses asynchronous threads to avoid IO block during the database access, the same way in which Erlang asynchronous drivers were implemented. We followed the syntax of Erlydb (erlang_mysql_driver) to design the APIs. For one database access request, the parameters will be passed to driver and processed in asynchronous threads. The erlang postgres driver epgsql is also quite a bit faster than postgrex. Standalone database performance doesn’t matter as much if the drivers don’t cut it. Mysql-otp is fairly new, but hopefully, it will hold up. A driver in Erlang is a library written in C, which is linked to the Erlang emulator and called from Erlang. Drivers can be used when C is more suitable than Erlang, to speed up things, or to provide access to OS resources not directly accessible from Erlang. A driver can be dynamically loaded, as a shared library (known as a DLL on Windows), or statically loaded, linked with the emulator when it is compiled and linked.

Connector/J provides driver support for connecting to MySQL from Java applications using the standard Java Database Connectivity (JDBC) API. epgsql Is a pure Erlang database driver for PostgreSQL. Epgsql supports conversion of db types to native Erlang types and the PostgreSQL binary format for. A driver in Erlang is a library written in C, which is linked to the Erlang emulator and called from Erlang. Drivers can be used when C is more suitable than.
