Enum Constant Summary

Enum Constants

Enum Constant	Description
FULL	During ejection, everything (including key, metadata, and value) will be ejected.
NO_EVICTION	Couchbase Server keeps all data until explicitly deleted, but will reject any new data if you reach the quota (dedicated memory) you set for your bucket.
NOT_RECENTLY_USED	When the memory quota is reached, Couchbase Server ejects data that has not been used recently.
VALUE_ONLY	During ejection, only the value will be ejected (key and metadata will remain in memory).

Method Summary

Modifier and Type	Method	Description
String	alias()
static EvictionPolicyType	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Details

FULL

public static final EvictionPolicyType FULL

During ejection, everything (including key, metadata, and value) will be ejected.

Full Ejection reduces the memory overhead requirement, at the cost of performance.

This value is only valid for buckets of type BucketType.COUCHBASE.

VALUE_ONLY

public static final EvictionPolicyType VALUE_ONLY

During ejection, only the value will be ejected (key and metadata will remain in memory).

Value Ejection needs more system memory, but provides better performance than Full Ejection.

This value is only valid for buckets of type BucketType.COUCHBASE.

NOT_RECENTLY_USED

public static final EvictionPolicyType NOT_RECENTLY_USED

When the memory quota is reached, Couchbase Server ejects data that has not been used recently.

This value is only valid for buckets of type BucketType.EPHEMERAL.

NO_EVICTION

public static final EvictionPolicyType NO_EVICTION

Couchbase Server keeps all data until explicitly deleted, but will reject any new data if you reach the quota (dedicated memory) you set for your bucket.

This value is only valid for buckets of type BucketType.EPHEMERAL.

Method Details

values

public static EvictionPolicyType[] values()

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

Returns:

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

valueOf

public static EvictionPolicyType 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
