Enum Constant Summary

Enum Constants

Enum Constant	Description
NO_REUSE	No re-use, will pass null into the relevant code paths, which will result in new objects getting allocated on the fly, and needing to be garbage collected.
SINGLETON_THREAD_LOCAL	Thread-local per JVM.
THREAD_LOCAL_PER_INGESTION_TASK	Thread-local per ActiveActiveStoreIngestionTask.

Method Summary

Modifier and Type	Method	Description
Supplier<IngestionTaskReusableObjects>	supplier()
static IngestionTaskReusableObjects.Strategy	valueOf(String name)	Returns the enum constant of this class with the specified name.
static IngestionTaskReusableObjects.Strategy[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

NO_REUSE

public static final IngestionTaskReusableObjects.Strategy NO_REUSE

No re-use, will pass null into the relevant code paths, which will result in new objects getting allocated on the fly, and needing to be garbage collected.

THREAD_LOCAL_PER_INGESTION_TASK

public static final IngestionTaskReusableObjects.Strategy THREAD_LOCAL_PER_INGESTION_TASK

Thread-local per ActiveActiveStoreIngestionTask. This avoids hot path allocations but is likely not very efficient, since there can be many AASIT and each will have its own independent set of objects, even if/when the AASIT becomes dormant. This is the first mode which was built, and it is considered stable.

SINGLETON_THREAD_LOCAL

public static final IngestionTaskReusableObjects.Strategy SINGLETON_THREAD_LOCAL

Thread-local per JVM. Likely the most efficient.

Method Details

values

public static IngestionTaskReusableObjects.Strategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static IngestionTaskReusableObjects.Strategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

supplier
