Aerospike Database 7.0 Release Notes

Aerospike Database Release Notes 7.0

November 15, 2023

Aerospike Database software version 7.0 is now available.

New in this version

This version implements a variety of feature requests and improvements to enhance performance, usability and reliability.

New features

• New storage engine for in-memory namespaces
  • Unified write-block storage format
  • Aerospike Enterprise Edition (EE) and Standard Edition (SE) store data in shared memory segments
  • Fast restarts for EE and SE in-memory namespaces
  • Compression available for in-memory namespaces
• Default TTL can now be configured at set level
• Secondary indexes can be built on the bytes data type (BLOBs)
• See the detailed complete list of all new features

Updates

• Server UDF subsystem upgraded to Lua version 5.4
• Aerospike Tools 10.0
• Removed limit on number of unique bin names per namespace
• Increased the maximum number of sets per namespace to 4095
• An optimization for data-in-memory namespaces with storage-backed persistence, where hot keys that remain exactly the same size between writes were written in-place, has been removed in Server 7.0 as part of AER-6666.
• API changes
  • The device_size and memory_size expressions are now deprecated. Use the new expression record_size instead.
  • Developer API option to keep a CDT index on a per-bin basis is available for any storage engine
• See Platform support and compatibility for all currently supported platforms

Configuration changes

• Before upgrading to 7.0, from pre-7.0, cluster-name must be set dynamically on all nodes in the pre-7.0 cluster.
• index-type flash does not work with storage-engine pmem or storage-engine memory.
• See configuration changes for namespace data storage and data retention.
