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

values
public static EvictionPolicyType[] 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 (EvictionPolicyType c : EvictionPolicyType.values()) System.out.println(c);
- 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 nameNullPointerException
- if the argument is null
