Class DataSourceFactory

java.lang.Object

io.dropwizard.db.DataSourceFactory

public class DataSourceFactory
extends Object

A factory for pooled ManagedDataSources.

Configuration Parameters:

Name	Default	Description
driverClass	REQUIRED	The full name of the JDBC driver class.
url	REQUIRED	The URL of the server.
user	REQUIRED	The username used to connect to the server.
password	none	The password used to connect to the server.
abandonWhenPercentageFull	0	Connections that have been abandoned (timed out) won't get closed and reported up unless the number of connections in use are above the percentage defined by abandonWhenPercentageFull. The value should be between 0-100.
alternateUsernamesAllowed	false	Set to true if the call getConnection(username,password) is allowed. This is used for when the pool is used by an application accessing multiple schemas. There is a performance impact turning this option on, even when not used.
commitOnReturn	false	Set to true if you want the connection pool to commit any pending transaction when a connection is returned.
autoCommitByDefault	JDBC driver's default	The default auto-commit state of the connections.
readOnlyByDefault	JDBC driver's default	The default read-only state of the connections.
properties	none	Any additional JDBC driver parameters.
defaultCatalog	none	The default catalog to use for the connections.
defaultTransactionIsolation	JDBC driver default	The default transaction isolation to use for the connections. Can be one of none, default, read-uncommitted, read-committed, repeatable-read, or serializable.
useFairQueue	true	If true, calls to getConnection are handled in a FIFO manner.
initialSize	10	The initial size of the connection pool.
minSize	10	The minimum size of the connection pool.
maxSize	10	The maximum size of the connection pool.
initializationQuery	none	A custom query to be run when a connection is first created.
logAbandonedConnections	false	If true, logs stack traces of abandoned connections.
logValidationErrors	false	If true, logs errors when connections fail validation.
maxConnectionAge	none	If set, connections which have been open for longer than maxConnectionAge are closed when returned.
maxWaitForConnection	30 seconds	If a request for a connection is blocked for longer than this period, an exception will be thrown.
minIdleTime	1 minute	The minimum amount of time an connection must sit idle in the pool before it is eligible for eviction.
validationQuery	SELECT 1	The SQL query that will be used to validate connections from this pool before returning them to the caller or pool. If specified, this query does not have to return any data, it just can't throw a SQLException.
checkConnectionWhileIdle	true	Set to true if query validation should take place while the connection is idle.
checkConnectionOnBorrow	false	Whether or not connections will be validated before being borrowed from the pool. If the connection fails to validate, it will be dropped from the pool, and another will be borrowed.
checkConnectionOnConnect	false	Whether or not connections will be validated before being added to the pool. If the connection fails to validate, it won't be added to the pool.
checkConnectionOnReturn	false	Whether or not connections will be validated after being returned to the pool. If the connection fails to validate, it will be dropped from the pool.
autoCommentsEnabled	true	Whether or not ORMs should automatically add comments.
evictionInterval	5 seconds	The amount of time to sleep between runs of the idle connection validation, abandoned cleaner and idle pool resizing.
validationInterval	30 seconds	To avoid excess validation, only run validation once every interval.
