Aerospike Database 6.1 is now Generally Available, offering enhanced secondary index features and improved Cross-Datacenter Replication (XDR) throughput for rehydration and recovery use cases. The release supports secondary indexes on nested elements of documents, reducing limitations to only indexing top-level elements of a JSON document. It also introduces warm start support for secondary indexes in Enterprise Edition, significantly reducing operational impact during restarts. Additionally, the release provides support for indexing whole namespaces, enhanced throughput for XDR, and cardinality information through info calls, allowing for optimized query performance. Secondary index names are now limited to 64 characters, and the release includes significant improvements in performance, scalability, and data distribution capabilities.
