Method Details

from

static AgroalDataSource from(Supplier<AgroalDataSourceConfiguration> configurationSupplier,
 AgroalDataSourceListener... listeners)
                      throws SQLException

Create an AgroalDataSource from a supplier of the configuration.

Throws:

SQLException

from

static AgroalDataSource from(AgroalDataSourceConfiguration configuration,
 AgroalDataSourceListener... listeners)
                      throws SQLException

Create an AgroalDataSource from configuration.

Throws:

SQLException

getConfiguration

AgroalDataSourceConfiguration getConfiguration()

Allows inspection of the configuration. Some properties allow read / write.

getMetrics

AgroalDataSourceMetrics getMetrics()

Allows access to metrics. If metrics are not enabled, returns default values.

flush

void flush(AgroalDataSource.FlushMode mode)

Performs a flush action on the connections of the pool.

setPoolInterceptors

void setPoolInterceptors(Collection<? extends AgroalPoolInterceptor> interceptors)

Sets pool interceptors.

getPoolInterceptors

List<AgroalPoolInterceptor> getPoolInterceptors()

Get the list of pool interceptors. Interceptors are sorted from high to low priority.

isHealthy

default boolean isHealthy(boolean newConnection)
                   throws SQLException

Performs a health check. The newConnection parameter determines that a new database connection is established for this purpose, otherwise attempts to get a connection from the pool. WARNING: Using a new connection may cause the size of the pool to go over max-size.

Throws:

SQLException

close

void close()
