What are the main features of Hazelcast?

• Scalability

• Speed

DEMO TIME

<backup-count>1</backup-count>

max backup count is 6

Backups increase memory usage since they are also kept in memory.

Data Backup

Rebalance Data on New Node

Distributed Maps

Fixed number of partitions (default 271)Each key falls into a partitionpartitionId = hash(keyData)%PARTITION_COUNTPartition ownerships are reassigned upon membership change

New Node Added

Client/Server Architecture

Embedded Architecture

Deployment Options

Great for early stages of rapid application development and iteration

Necessary for scale up or scale out deployments – decouples upgrading of clients and cluster for long term TCO
