Modifier and Type	Method	Description
`default void`	`addQueryPassthroughCapabilityIfEnabled(com.google.common.collect.ImmutableMap.Builder<String,List<OptimizationSubType>> capabilities, Map<String,String> configOptions)`	Adds the query passthrough implementation, if user has not disabled it, to the connector's capabilities
`default boolean`	`allowQueryPassthrough(Map<String,String> configOptions)`	A method that checks the Lambda's environment variables to see if QPT is disabled/enabled
`default void`	`customConnectorVerifications(Map<String,String> engineQptArguments)`	Provides a mechanism to perform custom connector verification logic.
`List<String>`	`getFunctionArguments()`
`String`	`getFunctionName()`
`String`	`getFunctionSchema()`
`default String`	`getFunctionSignature()`	Returns the full function schema and name
`org.slf4j.Logger`	`getLogger()`	note: due to needing to stay compatible with JDK8; we can't use JDK9 private method
`default List<OptimizationSubType>`	`getQueryPassthroughCapabilities()`	Creates a list of Optimization that includes the query passthrough definition
`default void`	`verify(Map<String,String> engineQptArguments)`	verify that the arguments returned by the engine are the same that the connector defined And call on any connector-custom verification
`default boolean`	`verifyFunctionSignature(Map<String,String> argumentValues)`	Verifying that the query passthrough function signature is the one expected by the connector
