+ /**
+  * 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.
