Enum CacheStrategy

java.lang.Object

java.lang.Enum<CacheStrategy>

com.codedstream.otterstream.inference.cache.CacheStrategy

All Implemented Interfaces:

Serializable, Comparable<CacheStrategy>

public enum CacheStrategy
extends Enum<CacheStrategy>

Defines caching strategies for ML inference operations in Otter Stream.

Cache strategies determine how inference results are cached to improve performance and reduce redundant model computations. Choose the appropriate strategy based on your use case and data characteristics.

Usage Example:

 CacheStrategy strategy = CacheStrategy.INPUT_HASH;
 System.out.println(strategy.getDescription());
 

Since:

1.0.0

Enum Constant Summary

Enum Constants

Enum Constant	Description
FEATURE_BASED	Cache based on specific feature values - granular caching control
INPUT_HASH	Cache based on hash of input features - best for identical inputs
MODEL_OUTPUT	Cache model outputs for reuse - useful for frequently accessed predictions
NONE	No caching - all inferences go directly to the model

Method Summary

Modifier and Type	Method	Description
String	getDescription()	Gets the human-readable description of this caching strategy.
static CacheStrategy	valueOf(String name)	Returns the enum constant of this type with the specified name.
static CacheStrategy[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

NONE

public static final CacheStrategy NONE

No caching - all inferences go directly to the model

INPUT_HASH

public static final CacheStrategy INPUT_HASH

Cache based on hash of input features - best for identical inputs

MODEL_OUTPUT

public static final CacheStrategy MODEL_OUTPUT

Cache model outputs for reuse - useful for frequently accessed predictions

FEATURE_BASED

public static final CacheStrategy FEATURE_BASED

Cache based on specific feature values - granular caching control

Method Detail

values

public static CacheStrategy[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CacheStrategy c : CacheStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static CacheStrategy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null

getDescription

public String getDescription()

Gets the human-readable description of this caching strategy.

Returns:

description of the caching approach
