@ThreadSafe @Deprecated public interface SegmentedAdvancedLoadWriteStore<K,V> extends AdvancedLoadWriteStore<K,V>, AdvancedCacheExpirationWriter<K,V>
Deprecated.since 11.0 replaced byNonBlockingStore
An interface implementing bothAdvancedCacheWriter
andAdvancedCacheLoader
as well as overrides of those methods that can be optimized when a segment is already known for the key or a subset of segments are to be used instead of the entire store.Various methods on this interface may be invoked even if the store is configured as being segmented. That is whether the configuration is true for
StoreConfiguration.segmented()
. Each method is documented as to if this can occur or not.- Since:

Method Detail

get
MarshallableEntry<K,V> get(int segment, Object key)
Deprecated.Fetches an entry from the storage given a segment to optimize this lookup based on. If aMarshallableEntry
needs to be created here,InitializationContext.getMarshallableEntryFactory()
andInitializationContext.getByteBufferFactory()
should be used.The provided segment may be used for performance purposes, however it it is acceptable to ignore this argument.
This method may be invoked invoked irrespective if the store is
StoreConfiguration.segmented()
.- Parameters:
segment
- the segment that the key maps tokey
- the key of the entry to fetch- Returns:
- the entry, or null if the entry does not exist
- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage
-
contains
boolean contains(int segment, Object key)
Deprecated.Returns true if the storage contains an entry associated with the given key in the given segmentThe provided segment may be used for performance purposes, however it it is acceptable to ignore this argument.
This method may be invoked invoked irrespective if the store is
StoreConfiguration.segmented()
.- Parameters:
segment
- the segment that the key maps tokey
- the key to see if exists- Returns:
- true if the key is present in this loader with a given segment
- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage
-
write
void write(int segment, MarshallableEntry<? extends K,? extends V> entry)
Deprecated.Persists the entry to the storage with the given segment to optimize future lookups.The provided segment may be used for performance purposes, however it it is acceptable to ignore this argument.
This method may be invoked invoked irrespective if the store is
StoreConfiguration.segmented()
.- Parameters:
segment
- the segment to persist this entry toentry
- the entry to write to the store- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage- See Also:
MarshallableEntry
-
delete
boolean delete(int segment, Object key)
Deprecated.Removes the entry for the provided key which is in the given segment. This method then returns whether the entry was removed or not.The provided segment may be used for performance purposes, however it it is acceptable to ignore this argument.
This method may be invoked invoked irrespective if the store is
StoreConfiguration.segmented()
.- Parameters:
segment
- the segment that this key maps tokey
- the key of the entry to remove- Returns:
- true if the entry existed in the persistent store and it was deleted.
- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage
-
size
int size(IntSet segments)
Deprecated.Returns the number of elements in the store that map to the given segments that aren't expired.The segments here must be adhered to and the size must not count any entries that don't belong to the provided segments.
This method is not invoked invoked when the store is not configured to be
StoreConfiguration.segmented()
.- Parameters:
segments
- the segments which should have their entries counted. Always non null.- Returns:
- the count of entries in the given segments
- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage
-
publishKeys
org.reactivestreams.Publisher<K> publishKeys(IntSet segments, Predicate<? super K> filter)
Deprecated.Publishes all the keys that map to the given segments from this store. The given publisher can be used by as manySubscriber
s as desired. Keys are not retrieved until a given Subscriber requests them from theSubscription
.Stores will return only non expired keys
The segments here must be adhered to and the keys published must not include any that don't belong to the provided segments.
This method is not invoked invoked when the store is not configured to be
StoreConfiguration.segmented()
.- Parameters:
segments
- the segments that the keys must map to. Always non null.filter
- a filter- Returns:
- a publisher that will provide the keys from the store
-
entryPublisher
org.reactivestreams.Publisher<MarshallableEntry<K,V>> entryPublisher(IntSet segments, Predicate<? super K> filter, boolean fetchValue, boolean fetchMetadata)
Deprecated.Publishes all entries from this store. The given publisher can be used by as manySubscriber
s as desired. Entries are not retrieved until a given Subscriber requests them from theSubscription
.If fetchMetadata is true this store must guarantee to not return any expired entries.
The segments here must be adhered to and the entries published must not include any that don't belong to the provided segments.
This method is not invoked invoked when the store is not configured to be
StoreConfiguration.segmented()
.StoreConfiguration.segmented()
.- Parameters:
segments
- the segments that the keys of the entries must map to. Always non null.filter
- a filter on the keys of the entries that if passed will allow the given entry to be returned from the publisherfetchValue
- whether the value should be included in the marshalled entryfetchMetadata
- whether the metadata should be included in the marshalled entry- Returns:
- a publisher that will provide the entries from the store that map to the given segments
-
clear
void clear(IntSet segments)
Deprecated.Removes all the data that maps to the given segments from the storage.This method must only remove entries that map to the provided segments.
This method may be invoked irrespective if the configuration is
StoreConfiguration.segmented()
or not.- Parameters:
segments
- data mapping to these segments are removed. Always non null.- Throws:
PersistenceException
- in case of an error, e.g. communicating with the external storage
-
addSegments
default void addSegments(IntSet segments)
Deprecated.Invoked when a node becomes an owner of the given segments. Note this method is only invoked for non shared store implementations.This method may be invoked irrespective if the configuration is
StoreConfiguration.segmented()
or not.- Parameters:
segments
- segments to associate with this store
-
removeSegments
default void removeSegments(IntSet segments)
Deprecated.Invoked when a node loses ownership of a segment. The provided segments are the ones this node no longer owns. Note this method is only invoked for non shared store implementations.This method may be invoked irrespective if the configuration is
StoreConfiguration.segmented()
or not.StoreConfiguration.segmented()
.- Parameters:
segments
- segments that should no longer be associated with this store
-
purge
default void purge(Executor executor, AdvancedCacheExpirationWriter.ExpirationPurgeListener<K,V> listener)
Deprecated.Using the thread in the pool, removed all the expired data from the persistence storage. For each removed entry, the supplied listener is invoked. This should be preferred toAdvancedCacheWriter.purge(Executor, PurgeListener)
since it allows for value and metadata to be provided which provides more accurate expiration when coordination is required.- Specified by:
purge
in interfaceAdvancedCacheExpirationWriter<K,V>
- Parameters:
executor
- the executor to invoke the given command onlistener
- the listener that is notified for each expired entry
