As your heap gets bigger, garbage collection might cause your application to pause tens 345 of seconds, badly effecting your application performance and response times. Elastic Memory is 346 Hazelcast with off-heap memory storage to avoid GC pauses. Even if you have terabytes of cache 347 in-memory with lots of updates, GC will have almost no effect; resulting in more predictable latency 348 and throughput. 349 </para> 350 </listitem> 351 352 <listitem> 353 <para>Security Framework<superscript>(Enterprise Edition Only)</superscript>: Hazelcast Security is JAAS 354 based pluggable security framework which can be used to authenticate both cluster members and 355 clients and do access control checks on client operations. With the security framework, take control 356 of who can be part of the cluster or connect as client and which operations are allowed or not. 357 </para> 358 </listitem> 359 360 <listitem> 361 <para>Native C# Client<superscript>(Enterprise Edition Only)</superscript>: Just like our Native Java 362 Client, it supports all map, multimap, queue, topic operations including listeners and queries. 363 </para> 364 </listitem> 365 366 <listitem> 367 <para>Distributed Backups: Data owned by a member will be evenly backed up by all the other members. In 368 other word, every member takes equal responsibility to backup every other node. This leads to better 369 memory usage and less influence in the cluster when you add/remove nodes. The new backup system 370 makes it possible to form backup-groups so that you can have backups and owners fall into different 371 groups. 372 </para> 373 </listitem> 374 <listitem> 375 <para>Parallel IO: Number of socket selector threads can be configured. You can have more IO threads, if 376 you have good number of CPU/cores and high-throughput network. 377 </para> 378 </listitem> 379 <listitem> 380 <para>Connection Management: Hazelcast 2.0 is more tolerant to connection failures. On connection 381 failure it tries to repair it 382 before declaring the member as dead. So now it is ok to have short socket disconnections… No problem 383 if your virtual server migrates to a new host. 384 </para> 385 </listitem> 386 <listitem> 387 <para>Listeners such as migration, membership and map indexes can be added with configuration.</para> 388 </listitem> 389 <listitem> 390 <para>New Event Objects: Event Listeners for Queue/List/Set/Topic were delivering the item itself on 391 event methods. That’s 392 why the items had to be deserialized by Hazelcast Threads before invoking the listeners. Sometimes 393 this was causing class loader problems too. With 2.0, we have introduced new event containers for 394 Queue/List/Set and Topic just like Map has EntryEvent. The new listeners now receive ItemEvent and 395 Message objects respectively. The actual items are deserialized only if you call the appropriate get 396 method on the event objects. This is where we brake the compatibility with the older versions of 397 Hazelcast. 398 </para> 399 </listitem> 400 <listitem> 401 <para>ClientConfig API: We had too many of factory methods to instantiate a HazelcastClient.
