public final class JdbcAppender
extends AbstractDatabaseAppender<JdbcDatabaseManager>

This Appender writes logging events to a relational database using standard JDBC mechanisms. It takes a list of ColumnConfigs with which it determines how to save the event data into the appropriate columns in the table. A ConnectionSource plugin instance instructs the appender (and JdbcDatabaseManager) how to connect to the database. This appender can be reconfigured at run time.

Factory method for creating a JDBC appender within the plugin manager.

name - The name of the appender.
ignore - If "true" (default) exceptions encountered when appending events are logged; otherwise they are propagated to the caller.
filter - The filter, if any, to use.
connectionSource - The connections source from which database connections should be retrieved.
bufferSize - If an integer greater than 0, this causes the appender to buffer log events and flush whenever the buffer reaches this size.
tableName - The name of the database table to insert log events into.
columnConfigs - Information about the columns that log event data should be inserted into and how to insert that data.
