All Superinterfaces:

AutoCloseable, javax.cache.Cache<K,V>, Closeable, IgniteAsyncSupport, Iterable<javax.cache.Cache.Entry<K,V>>
```
public interface IgniteCache<K,V>
extends javax.cache.Cache<K,V>, IgniteAsyncSupport
```
Main entry point for all Data Grid APIs. You can get a named cache by calling Ignite.cache(String) method.
Functionality
This API extends Cache API which contains JCache (JSR107) cache functionality and documentation. In addition to Cache functionality this API provides:
- Ability to perform basic atomic Map-like operations available on JCache API.
- Ability to bulk load cache via loadCache(IgniteBiPredicate, Object...) method.
- Distributed lock functionality via lock(Object) methods.
- Ability to query cache using Predicate, SQL, and Text queries via query(Query) method.
- Ability to collect cache and query metrics.
- Ability to force partition rebalancing via rebalance() methopd (in case if delayed rebalancing was configured.)
- Ability to peek into memory without doing actual get(...) from cache via localPeek(Object, CachePeekMode...) methods
- Ability to evict and promote entries from on-heap to off-heap or swap and back.
- Ability to atomically collocate compute and data via invoke(Object, CacheEntryProcessor, Object...) methods.
Transactions
Cache API supports transactions. You can group and set of cache methods within a transaction to provide ACID-compliant behavior. See IgniteTransactions for more information.
Methods which can be used inside transaction (put, get...) throw TransactionException. See TransactionException for more information.

    plc - Expire policy to use.
    
    Returns:
    
    Cache instance with the specified expiry policy set.

```
    Gets an instance of IgniteCache that will be allowed to execute cache read operations regardless of partition loss policy.
    
    Returns:
    
    Cache without partition loss protection.
  - withReadRepair
```
IgniteCache<K,V> withReadRepair(ReadRepairStrategy strategy)
```
    This is an experimental API.
    Gets an instance of IgniteCache that will perform backup nodes check on each get attempt.
    Read Repair means that each backup node will be checked to have the same entry as the primary node has.
    In case consistency violations were found, the values across the topology will be replaced by repaired values according to the chosen strategy, see ReadRepairStrategy for the details.
    A consistency violation exception will be thrown when the repair is impossible.
    CacheConsistencyViolationEvent will be recorded for each violation in case it's configured as recordable.
    
    For transactional caches, values will be repaired:
    
    automatically for transactions that have TransactionConcurrency.OPTIMISTIC concurrency mode or TransactionIsolation.READ_COMMITTED isolation level,
    
    at commit() phase for transactions that have TransactionConcurrency.PESSIMISTIC concurrency mode and isolation level other than TransactionIsolation.READ_COMMITTED
    
    Warning:
    This proxy usage does not guarantee "all copies check" in case the value have been already cached inside the transaction. In case you don't use a READ_COMMITTED isolation mode and already have a cached value, for example have already read the value or performed a write, you'll just get the cached value.
    
    For atomic caches, values will be repaired automatically.
    Warning:
    Due to the nature of an atomic cache, false-positive results can be observed. For example, an attempt to check consistency under cache's loading may lead to a consistency violation exception. By default, the implementation tries to check the given key three times. The number of attempts can be changed using IgniteSystemProperties.IGNITE_NEAR_GET_MAX_REMAPS property.
    
    A consistency check is incompatible with the following cache configurations:
    
    Caches without backups.
    
    Near caches.
    
    Caches that use "read-through" mode.

    containsKey(K) && containsKeyAsync(K)

    get(K) && getAsync(K)
    
    getAll(java.util.Set<? extends K>) && getAllAsync(java.util.Set<? extends K>)
    Parameters:
    
    strategy - Read Repair strategy.
    
    Returns:
    
    Cache with explicit consistency check on each read and repair if necessary.
  - withKeepBinary
```
<K1,V1> IgniteCache<K1,V1> withKeepBinary()
```
    Returns cache that will operate with binary objects.
    Cache returned by this method will not be forced to deserialize binary objects, so keys and values will be returned from cache API methods without changes. Therefore, signature of the cache can contain only following types:
    
    org.apache.ignite.binary.BinaryObject for binary classes
    
    All primitives (byte, int, ...) and there boxed versions (Byte, Integer, ...)
    
    Arrays of primitives (byte[], int[], ...)
    
    String and array of Strings
    
    UUID and array of UUIDs
    
    Date and array of Dates
    
    Timestamp and array of Timestamps
    
    Enums and array of enums
    
    Maps, collections and array of objects (but objects inside them will still be converted if they are binary)
    
    For example, if you use Integer as a key and Value class as a value (which will be stored in binary format), you should acquire following projection to avoid deserialization:
    IgniteCache<Integer, BinaryObject> prj = cache.withKeepBinary(); // Value is not deserialized and returned in binary format. BinaryObject po = prj.get(1);
    
    Note that this method makes sense only if cache is working in binary mode if default marshaller is used. If not, this method is no-op and will return current cache.
    Type Parameters:
    
    V1 - Type of the cache value binary objects.
    
    K1 - Type of the cache key.
    
    Returns:
    
    New cache instance for binary objects.

```
    Delegates to CacheStore.loadCache(IgniteBiInClosure,Object...) method to load state from the underlying persistent storage. The loaded values will then be given to the optionally passed in predicate, and, if the predicate returns true, will be stored in cache. If predicate is null, then all loaded values will be stored in cache.
    Note that this method does not receive keys as a parameter, so it is up to CacheStore implementation to provide all the data to be loaded.
    This method is not transactional and may end up loading a stale value into cache if another thread has updated the value immediately after it has been loaded. It is mostly useful when pre-loading the cache from underlying data store before start, or for read-only caches.
    
    Parameters:
    
    p - Optional predicate (may be null). If provided, will be used to filter values to be put into cache.
    
    args - Optional user arguments to be passed into CacheStore.loadCache(IgniteBiInClosure, Object...) method.

             throws javax.cache.CacheException,
                    TransactionException
```
    Stores given key-value pair in cache only if cache had no previous mapping for it. If cache previously contained value for the given key, then this value is returned. In case of CacheMode.PARTITIONED or CacheMode.REPLICATED caches, the value will be loaded from the primary node, which in its turn may load the value from the swap storage, and consecutively, if it's not in swap, from the underlying persistent storage. If value has to be loaded from persistent storage, CacheLoader.load(Object) method will be used.
    If the returned value is not needed, method putIfAbsent(Object, Object) should always be used instead of this one to avoid the overhead associated with returning of the previous value.
    If write-through is enabled, the stored value will be persisted to CacheStore via CacheWriter.write(javax.cache.Cache.Entry) method.
    Transactions
    This method is transactional and will enlist the entry into ongoing transaction if there is one.
    
    Parameters:
    
    key - Key to store in cache.
    
    val - Value to be associated with the given key.
    
    Returns:
    
    Previously contained value regardless of whether put happened or not (null if there was no previous value).
    
    Throws:
    
    NullPointerException - If either key or value are null.
    
    javax.cache.CacheException - If put operation failed.
    
    TransactionException - If operation within transaction is failed.

In case of CacheMode.PARTITIONED or CacheMode.REPLICATED caches, the value will be loaded from the primary node, which in its turn may load the value from the swap storage, and consecutively, if it's not in swap, from the underlying persistent storage. If value has to be loaded from persistent storage, CacheLoader.load(Object) method will be used.
    If the returned value is not needed, method putIfAbsentAsync(Object, Object) should always be used instead of this one to avoid the overhead associated with returning of the previous value.
    If write-through is enabled, the stored value will be persisted to CacheStore via CacheWriter.write(javax.cache.Cache.Entry) method.
    Transactions
    This method is transactional and will enlist the entry into ongoing transaction if there is one.
    
    Parameters:
    
    key - Key to store in cache.
    
    val - Value to be associated with the given key.
    
    Returns:
    
    a Future representing pending completion of the operation.
    
    Throws:
    
    NullPointerException - If either key or value are null.
    
    javax.cache.CacheException - If put operation failed.
    
    TransactionException - If operation within transaction is failed.
  - lock
```
Lock lock(K key)

```
    Asynchronously invokes each EntryProcessor from map's values against the correspondent Cache.Entry specified by map's key set.
    If an Cache.Entry does not exist for the specified key, an attempt is made to load it (if a loader is configured) or a surrogate Cache.Entry, consisting of the key and a value of null is provided.
    The order that the entries for the keys are processed is undefined. Implementations may choose to process the entries in any order, including concurrently. Furthermore there is no guarantee implementations will use the same EntryProcessor instance to process each entry, as the case may be in a non-local cache topology.
    The result of executing the EntryProcessor is returned in the future as a Map of EntryProcessorResults, one result per key. Should the EntryProcessor or Caching implementation throw an exception, the exception is wrapped and re-thrown when a call to EntryProcessorResult.get() is made.
    Please refer to documentation for CacheAtomicityMode.ATOMIC for information on system behavior in crash scenarios for atomic caches.
    Keys are locked in the order in which they appear in map. It is caller's responsibility to make sure keys always follow same order, such as by using TreeMap. Using unordered map, such as HashMap, while calling this method in parallel will lead to deadlock.
    
    Type Parameters:
    
    T - Type of the cache entry processing result.
    
    Parameters:
    
    map - Map containing keys and entry processors to be applied to values.
    
    args - Additional arguments to pass to the EntryProcessor.
    
    Returns:
    
    The map of EntryProcessorResults of the processing per key, if any, defined by the EntryProcessor implementation. No mappings will be returned for EntryProcessors that return a null value for a key.
    
    Throws:
    
    TransactionException - If operation within transaction is failed.

```
    Keys are locked in the order in which they appear in map. It is caller's responsibility to make sure keys always follow same order, such as by using TreeMap. Using unordered map, such as HashMap, while calling this method in parallel will lead to deadlock.

                        throws TransactionException
```
    Asynchronously copies all of the entries from the specified map to the Cache.
    The effect of this call is equivalent to that of calling putAsync(Object, Object) putAsync(k, v)} on this cache once for each mapping from key k to value v in the specified map.
    The order in which the individual puts occur is undefined.
    The behavior of this operation is undefined if entries in the cache corresponding to entries in the map are modified or removed while this operation is in progress. or if map is modified while the operation is in progress.
    In Default Consistency mode, individual puts occur atomically but not the entire putAll. Listeners may observe individual updates.

```
    Asynchronously removes the mapping for a key from this cache if it is present.
    More formally, if this cache contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The cache can contain at most one such mapping.)
    A future result is true if this cache previously associated the key, or false if the cache contained no mapping for the key.
    The cache will not contain a mapping for the specified key once the returned future is completed.

    Asynchronously invokes an CacheEntryProcessor against the Cache.Entry specified by the provided key. If an Cache.Entry does not exist for the specified key, an attempt is made to load it (if a loader is configured) or a surrogate Cache.Entry, consisting of the key with a null value is used instead.
    An instance of entry processor must be stateless as it may be invoked multiple times on primary and backup nodes in the cache. It is guaranteed that the value passed to the entry processor will be always the same.
    
    Type Parameters:
    
    T - Type of the cache entry processing result.
    
    Parameters:
    
    key - The key to the entry.
    
    entryProcessor - The CacheEntryProcessor to invoke.
    
    arguments - Additional arguments to pass to the CacheEntryProcessor.
    
    Returns:
    
    a Future representing pending completion of the operation.
    
    Throws:
    
    NullPointerException - If key or CacheEntryProcessor is null
    
    IllegalStateException - If the cache is Cache.isClosed()
    
    ClassCastException - If the implementation is configured to perform runtime-type-checking, and the key or value types are incompatible with those that have been configured for the Cache.
    
    javax.cache.processor.EntryProcessorException - If an exception is thrown by the CacheEntryProcessor, a Caching Implementation must wrap any Exception thrown wrapped in an EntryProcessorException.

  - close
```
void close()
```
    Closes this cache instance.
    For local cache equivalent to destroy(). For distributed caches, if called on clients, stops client cache, if called on a server node, just closes this cache instance and does not destroy cache data.
    After cache instance is closed another IgniteCache instance for the same cache can be created using Ignite.cache(String) method.

  - destroy
```
void destroy()
```
    Completely deletes the cache with all its data from the system on all cluster nodes.
  - rebalance
```
@Deprecated
IgniteFuture<Boolean> rebalance()
```
    Deprecated.
    Use baseline topology feature instead. Please, be aware this API will be removed in the next releases.
    
    This cache node to re-balance its partitions. This method is usually used when CacheConfiguration.getRebalanceDelay() configuration parameter has non-zero value. When many nodes are started or stopped almost concurrently, it is more efficient to delay rebalancing until the node topology is stable to make sure that no redundant re-partitioning happens.
    In case ofCacheMode.PARTITIONED caches, for better efficiency user should usually make sure that new nodes get placed on the same place of consistent hash ring as the left nodes, and that nodes are restarted before rebalanceDelay expires. To place nodes on the same place in consistent hash ring, use IgniteConfiguration.setConsistentId(Serializable) to make sure that a node maps to the same hash ID if re-started.
    See CacheConfiguration.getRebalanceDelay() for more information on how to configure rebalance re-partition delay.
    
    Returns:
    
    Future that will be completed when rebalancing is finished. Future.get() returns true when rebalance was successfully finished.
  - indexReadyFuture
```
IgniteFuture<?> indexReadyFuture()
```
    Returns future that will be completed when all indexes for this cache are ready to use.
    
    Returns:
    
    Future.
  - metrics
```
CacheMetrics metrics()
```
    Gets whole cluster snapshot metrics (statistics) for this cache.
    
    Returns:
    
    Cache metrics.
  - metrics
```
CacheMetrics metrics(ClusterGroup grp)
```
    Gets cluster group snapshot metrics for caches in cluster group.
    
    Parameters:
    
    grp - Cluster group.
    
    Returns:
    
    Cache metrics.
  - localMetrics
```
CacheMetrics localMetrics()
```
    Gets local snapshot metrics (statistics) for this cache.
    
    Returns:
    
    Cache metrics.
  - lostPartitions
```
Collection<Integer> lostPartitions()
```
    Gets a collection of lost partition IDs. This method provides a facility for fine-tuned handling of lost partitions. Once all lost partitions are considered recovered (for example, after the previously failed primary and backup nodes, that stored partition data in Ignite persistence, are booted) Ignite.resetLostPartitions(Collection) can used in order to clear lost flag making all partitions fully operational.
    
    Returns:
    
    Lost partitions.

    PartitionLossPolicy, EventType.EVT_CACHE_REBALANCE_PART_DATA_LOST, Ignite.resetLostPartitions(Collection)
  - enableStatistics
```
void enableStatistics(boolean enabled)
```
    Sets statistics enabled flag cluster wide for this cache.
    
    Parameters:
    
    enabled - Statistics enabled flag.
  - clearStatistics
```
void clearStatistics()
```
    Clear cluster statistics for this cache.
  - preloadPartition
```
void preloadPartition(int partition)
```
    Efficiently preloads cache primary partition into page memory.
    This is useful for fast iteration over cache partition data if persistence is enabled and the data is "cold".
    Preload will reduce available amount of page memory for subsequent operations and may lead to earlier page replacement.
    This method is irrelevant for in-memory caches. Calling this method on an in-memory cache will result in exception.
    
    Parameters:
    
    partition - Partition.
  - preloadPartitionAsync
```
IgniteFuture<Void> preloadPartitionAsync(int partition)
```
    Efficiently preloads cache partition into page memory.
    This is useful for fast iteration over cache partition data if persistence is enabled and the data is "cold".
    Preload will reduce available amount of page memory for subsequent operations and may lead to earlier page replacement.
    This method is irrelevant for in-memory caches. Calling this method on an in-memory cache will result in exception.
    
    Parameters:
    
    partition - Partition.
    
    Returns:
    
    A future representing pending completion of the partition preloading.
  - localPreloadPartition
```
boolean localPreloadPartition(int partition)
```
    Efficiently preloads cache partition into page memory if it exists on the local node.
    This is useful for fast iteration over cache partition data if persistence is enabled and the data is "cold".
    Preload will reduce available amount of page memory for subsequent operations and may lead to earlier page replacement.
    This method is irrelevant for in-memory caches. Calling this method on an in-memory cache will result in exception.
    
    Parameters:
    
    partition - Partition.
    
    Returns:
    
    True if partition was preloaded, false if it doesn't belong to local node.
