Feature Comparison

In-Memory & Key-Value Databases features side-by-side

Feature	GridGain 10/17 features	Hazelcast 10/17 features
Rich data structures beyond strings Lists, hashes, sets, sorted sets and streams stored and manipulated server-side, not only opaque blobs.	Yes	Yes
Per-key expiration and eviction policies Keys expire on a TTL, and the store evicts by LRU, LFU or random selection when memory is full.	Yes	Yes
Snapshot persistence to disk Periodic point-in-time dumps of the in-memory dataset written to disk for restart recovery.	Yes	No
Append-only log persistence Every write is appended to a durable log so a restart loses at most a second or so of data.	Yes	Yes
Replica failover with automatic promotion Replicas stream from the primary and a sentinel or cluster manager promotes one when the primary dies.	No	Yes
Horizontal clustering of the keyspace The keyspace is sharded across nodes with client redirection, growing capacity beyond one host.	Yes	Yes
Active-active geo replication Writes accepted in several regions and merged with conflict-free replicated data types.	No	No
Pub/sub messaging channels Clients publish to and subscribe on channels for lightweight fan-out messaging.	Yes	Yes
Atomic server-side scripting Scripts or functions run atomically on the server against several keys in one call.	No	No
SSD tiering beyond available RAM Less-used values spill to SSD so the dataset can exceed memory at a lower cost per gigabyte.	Yes	No
Secondary indexes on stored values Hashes or JSON values indexed on their fields and queried with filters, not only fetched by key.	Yes	Yes
Native JSON value type JSON stored as a native type with path-level reads and updates on the server.	No	No
Multi-threaded request handling The server executes commands on several cores in parallel rather than on one event loop.	Yes	Yes
Per-user command and key ACLs Named users restricted to specific commands and key patterns, with TLS on client connections.	No	Yes
Client-side caching invalidation The server tracks keys a client has cached locally and pushes an invalidation when they change.	Yes	Yes
Streams with consumer groups An append-only log type with consumer groups for at-least-once processing by several workers.	No	No
Keyspace memory reporting Commands or dashboards report memory per key, the largest keys and fragmentation.	No	No
Overall Rating	No reviews yet	No reviews yet
