Aerospike vs NATS
A side-by-side editorial comparison of Aerospike and NATS — release velocity, themes, recent moves, and the top alternatives to consider.
Aerospike vs NATS: at a glance
What is Aerospike?
Aerospike's 8.0 branch picks up three more CVE fixes two months after the July train.
Aerospike Community Edition maintains 7.1, 7.2, 8.0 and 8.1 branches. On 16 July it published seven releases in under two hours carrying two waves of security fixes across all four. In September 8.0.0.20 added three more CVE fixes (msgpack bounds checks in UDFs, a zero-length list element crash and a heap overflow in persisted lists and maps) along with cold-start set-membership and recluster fixes.
What is NATS?
NATS second release candidates add a config reload check and faster redelivery queues.
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.

◆ Current state
Aerospike Community Edition maintains 7.1, 7.2, 8.0 and 8.1 branches. On 16 July it published seven releases in under two hours carrying two waves of security fixes across all four. In September 8.0.0.20 added three more CVE fixes (msgpack bounds checks in UDFs, a zero-length list element crash and a heap overflow in persisted lists and maps) along with cold-start set-membership and recluster fixes.
◆ Where it's heading
msgpack parsing and collection data types keep producing memory-safety bugs across both the July and September releases. 8.0.0.19 does not appear in the feed, and no 8.1 or 7.x counterpart to 8.0.0.20 has shown up yet.
◆ Prediction
If the July pattern holds, matching 8.1 and 7.2 releases with the same three CVE fixes should follow.
NATS
5.0DEVOPS
NATS second release candidates add a config reload check and faster redelivery queues.
◆ Current state
NATS keeps the 2.14 and 2.15 lines in step, and on November 6 both got a second release candidate. The RCs make filtered filestore scans skip non-matching messages, stop redelivery queues from copying whole backlogs on each dequeue, and fix AckAll and gateway interest bugs. 2.15.3-RC.2 also adds a -t --test_reload flag that tells operators whether a config change needs a restart.
◆ Where it's heading
The project is in a hardening stretch on both lines, with JetStream efficiency and correctness fixes landing alongside small operator tools. Account-hash subject mappings from RC1 remain the main new routing feature heading to release.
◆ Prediction
Expect 2.15.3 and 2.14.10 final releases shortly, carrying the RC2 fixes and the reload check.
