+/**
+ * This interface provides a rich API for working with distributed caches. It includes the following
+ * main functionality:
+ * <ul>
+ * <li>
+ *  Various {@code 'get(..)'} methods to synchronously or asynchronously get values from cache.
+ *  All {@code 'get(..)'} methods are transactional and will participate in an ongoing transaction
+ *  if there is one.
+ * </li>
+ * <li>
+ *  Various {@code 'put(..)'}, {@code 'putIfAbsent(..)'}, and {@code 'replace(..)'} methods to
+ *  synchronously or asynchronously put single or multiple entries into cache.
+ *  All these methods are transactional and will participate in an ongoing transaction
+ *  if there is one.
+ * </li>
+ * <li>
+ *  Various {@code 'remove(..)'} methods to synchronously or asynchronously remove single or multiple keys
+ *  from cache. All {@code 'remove(..)'} methods are transactional and will participate in an ongoing transaction
+ *  if there is one.
+ * </li>
+ * <li>
+ *  Various {@code 'contains(..)'} method to check if cache contains certain keys or values locally.
+ * </li>
+ * <li>
+ *  Various {@code 'forEach(..)'}, {@code 'forAny(..)'}, and {@code 'reduce(..)'} methods to visit
+ *  every local cache entry within this projection.
+ * </li>
+ * <li>
+ *  Various {@code flagsOn(..)'}, {@code 'flagsOff(..)'}, and {@code 'projection(..)'} methods to
+ *  set specific flags and filters on a cache projection.
+ * </li>
+ * <li>
+ *  Methods like {@code 'keySet(..)'}, {@code 'values(..)'}, and {@code 'entrySet(..)'} to provide
+ *  views on cache keys, values, and entries.
+ * </li>
+ * <li>
+ *  Various {@code 'peek(..)'} methods to peek at values in global or transactional memory, swap
+ *  storage, or persistent storage.
+ * </li>
+ * <li>
+ *  Various {@code 'reload(..)'} methods to reload latest values from persistent storage.
+ * </li>
+ * <li>
+ *  Various {@code 'promote(..)'} methods to load specified keys from swap storage into
+ *  global cache memory.
+ * </li>
+ * <li>
+ *  Various {@code 'lock(..)'}, {@code 'unlock(..)'}, and {@code 'isLocked(..)'} methods to acquire, release,
+ *  and check on distributed locks on a single or multiple keys in cache. All locking methods
+ *  are not transactional and will not enlist keys into ongoing transaction, if any.
+ * </li>
+ * <li>
+ *  Various {@code 'clear(..)'} methods to clear elements from cache, and optionally from
+ *  swap storage. All {@code 'clear(..)'} methods are not transactional and will not enlist cleared
+ *  keys into ongoing transaction, if any.
+ * </li>
+ * <li>
+ *  Various {@code 'evict(..)'} methods to evict elements from cache, and optionally store
+ *  them in underlying swap storage for later access. All {@code 'evict(..)'} methods are not
+ *  transactional and will not enlist evicted keys into ongoing transaction, if any.
+ * </li>
+ * <li>
+ *  Various {@code 'txStart(..)'} methods to perform various cache
+ *  operations within a transaction (see {@link Transaction} for more information).
+ * </li>
+ * <li>
+ *  {@link #queries()} method to get an instance of {@link CacheQueries} service for working
+ *  with distributed cache queries.
+ * </li>
+ * <li>
+ *  Various {@code 'gridProjection(..)'} methods which provide {@link org.apache.ignite.cluster.ClusterGroup} only
+ *  for nodes on which given keys reside. All {@code 'gridProjection(..)'} methods are not
+ *  transactional and will not enlist keys into ongoing transaction.
+ * </li>
+ * <li>Method {@link GridCache#toMap()} to convert this interface into standard Java {@link ConcurrentMap} interface.
+ * </ul>
+ * <h1 class="header">Extended Put And Remove Methods</h1>
+ * All methods that end with {@code 'x'} provide the same functionality as their sibling
+ * methods that don't end with {@code 'x'}, however instead of returning a previous value they
+ * return a {@code boolean} flag indicating whether operation succeeded or not. Returning
+ * a previous value may involve a network trip or a persistent store lookup and should be
+ * avoided whenever not needed.
+ * <h1 class="header">Predicate Filters</h1>
+ * All filters passed into methods on this API are checked <b>atomically</b>. In other words the
+ * value returned by the methods is guaranteed to be consistent with the filters passed in. Note
+ * that filters are optional, and if not passed in, then methods will still work as is without
+ * filter validation.
+ * <h1 class="header">Transactions</h1>
+ * Cache API supports distributed transactions. All {@code 'get(..)'}, {@code 'put(..)'}, {@code 'replace(..)'},
+ * and {@code 'remove(..)'} operations are transactional and will participate in an ongoing transaction,
+ * if any. Other methods like {@code 'peek(..)'} or various {@code 'contains(..)'} methods may
+ * be transaction-aware, i.e. check in-transaction entries first, but will not affect the current
+ * state of transaction. See {@link Transaction} documentation for more information
+ * about transactions.
+ * <h1 class="header">Group Locking</h1>
+ * <i>Group Locking</i> is a feature where instead of acquiring individual locks, Ignite will lock
+ * multiple keys with one lock to save on locking overhead. There are 2 types of <i>Group Locking</i>:
+ * <i>affinity-based</i>, and <i>partitioned-based</i>.
+ * <p>
+ * With {@code affinity-based-group-locking} the keys are grouped by <i>affinity-key</i>. This means that
+ * only keys with identical affinity-key (see {@link org.apache.ignite.cache.affinity.CacheAffinityKeyMapped}) can participate in the
+ * transaction, and only one lock on the <i>affinity-key</i> will be acquired for the whole transaction.
+ * {@code Affinity-group-locked} transactions are started via
+ * {@link #txStartAffinity(Object, TransactionConcurrency, TransactionIsolation, long, int)} method.
+ * <p>
+ * With {@code partition-based-group-locking} the keys are grouped by partition ID. This means that
+ * only keys belonging to identical partition (see {@link org.apache.ignite.cache.affinity.CacheAffinity#partition(Object)}) can participate in the
+ * transaction, and only one lock on the whole partition will be acquired for the whole transaction.
+ * {@code Partition-group-locked} transactions are started via
+ * {@link #txStartPartition(int, TransactionConcurrency, TransactionIsolation, long, int)} method.
+ * <p>
+ * <i>Group locking</i> should always be used for transactions whenever possible. If your requirements fit either
+ * <i>affinity-based</i> or <i>partition-based</i> scenarios outlined above then <i>group-locking</i>
+ * can significantly improve performance of your application, often by an order of magnitude.
+ * <h1 class="header">Null Keys or Values</h1>
+ * Neither {@code null} keys or values are allowed to be stored in cache. If a {@code null} value
+ * happens to be in cache (e.g. after invalidation or remove), then cache will treat this case
+ * as there is no value at all.
+ * <h1 class="header">Peer Class Loading</h1>
+ * If peer-class-loading is enabled, all classes passed into cache API will be automatically deployed
+ * to any participating grid nodes. However, in case of redeployment, caches will be cleared and
+ * all entries will be removed. This behavior is useful during development, but should not be
+ * used in production.
+ * <h1 class="header">Portable Objects</h1>
+ * If an object is defined as portable Ignite cache will automatically store it in portable (i.e. binary)
+ * format. User can choose to work either with the portable format or with the deserialized form (assuming
+ * that class definitions are present in the classpath). By default, cache works with deserialized form
+ * (example shows the case when {@link Integer} is used as a key for a portable object):
+ * <pre>
+ * CacheProjection<Integer, Value> prj = Ignition.grid().cache(null);
+ *
+ * // Value will be serialized and stored in cache in portable format.
+ * prj.put(1, new Value());
+ *
+ * // Value will be deserialized since it's stored in portable format.
+ * Value val = prj.get(1);
+ * </pre>
+ * You won't be able to work with deserialized form if class definition for the {@code Value} is not on
+ * classpath. Even if you have the class definition, you should always avoid full deserialization if it's not
+ * needed for performance reasons. To work with portable format directly you should create special projection
+ * using {@link #keepPortable()} method:
+ * <pre>
+ * CacheProjection<Integer, GridPortableObject> prj = Ignition.grid().cache(null).keepPortable();
+ *
+ * // Value is not deserialized and returned in portable format.
+ * GridPortableObject po = prj.get(1);
+ * </pre>
+ * See {@link #keepPortable()} method JavaDoc for more details.
