Aerospike is introducing Aerospike Graph Service (AGS) 2.5.0, supporting strong consistency (SC) in graph workloads to enable guaranteed atomicity and isolation for real-time graph updates.
Backed by the new Aerospike Database 8.0, this release makes AGS a formidable engine for delivering accurate, scalable, and always-on graph solutions, the company said.
Without strong consistency, simultaneous updates, such as a mergeV() to unify identities and an addV() triggered by a new signal, can result in duplicate or orphaned profiles. In practice, this can lead to wasted ad spend, poor attribution, and degraded personalization—the exact opposite of what these platforms try to achieve.
AGS 2.5.0 solves these issues with transactional isolation for mutation queries, according to the company. That means:
- Atomic profile updates: No partial merges or lost edges during concurrent writes. All mutation Gremlin steps can now be executed atomically.
- Reliable attribution: Consistent, real-time identity graphs for better targeting accuracy.
- No orphaned identities: Query steps such as mergeV() and addE() are executed transactionally, eliminating data drift.
AGS 2.5.0 introduces support for Aerospike transactions, which apply to all mutation queries when the database namespace is configured with SC mode. With transactions enabled:
- Mutation queries are atomic and isolated, even during cluster splits.
- Read-only queries continue to follow an eventual consistency model for performance.
- Isolation levels differ for reads and writes, giving you the flexibility to optimize where it matters most.
Other highlights in 2.5.0 include key improvements such as:
- Query tracing: Get a detailed view into query execution paths to identify performance bottlenecks.
- Metric enhancements: New observability metrics (server_connection_queue_size and server_io_queue_size) offer deeper insights into AGS performance.
- Bug fixes: Smarter union step results, better timeout handling, and clearer error messages when using unsupported vertex IDs.
According to Aerospike, AGS 2.5.0 was designed with AdTech in mind, but its capabilities extend to any domain that relies on fast, consistent relationship data: fraud detection, personalization, recommendation engines, and more.
