Aerospike Database Release Notes 6.3

Aerospike Database Release Notes 6.3, March 30, 2023​

Aerospike Database software version 6.3 is now available.

New in this version​

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

Updates​

  • Support for OpenSSL 3.0 in Enterprise and Federal editions
  • Aerospike Tools 8.2.

New features​

  • Short query performance enhancement with inline-short-queries.
  • Using Aerospike for a multitenant data store is made easier by the new ability to cap the storage used by a set.
  • Log messages can now be streamed to syslog-compatible Unix domain sockets.
  • All Flash improvements - the namespace supervisor (NSUP) avoids duplicate resolution of records that have already been resolved during the relevant period.
  • Faster truncations
    • Truncate jobs leverage set indexes, significantly speeding them up. This optimization is skipped if the set contains tombstones.
    • truncate-threads now controls the number of threads used by a new truncate job. Users that truncate many sets concurrently should consider tuning this config.
  • Runtime resource protection:
  • Better Vault integration
    • Added support for Vault Enterprise through vault-namespace.
    • Refresh the Vault token by setting a new token and then dynamically configuring vault-token-file to the same path as before.
  • Deploy secondary indexes durably on Intel Optane™ Persistent Memory (PMem). The low cost, high performance, and memory density of PMem (compared to RAM) makes it possible for Aerospike users to create multiple secondary indexes on very large datasets.
  • The ability to compare a Map argument to a Map bin using Expressions with Document-oriented modeling.
  • New ORDERED_MAP and UNORDERED_MAP return types for map operations.
  • LuaJIT is back for clusters running on ARM64 machines.
  • This version and subsequent server 6.3.x Debian package software files (*.deb) and Red Hat Package Manager files (*.rpm) are now GPG Signed.

Breaking changes​

  • Reissued feature key files to customers through the support portal. For details, see 6.3 Special Upgrade.
  • Removed support for Ubuntu 18.04.
  • Removed support for Debian 10 on ARM64.
  • Customers using the audit trail security features must modify their config when upgrading to server 6.3 or later.

Prerequisites and notes​

Product lifecycle updates​

Long-term Support (LTS) releases are maintained and supported for 2.5 years (30 months). Interim releases are maintained and supported for 15 months. See Platform support for details.

Known issues​

  • If you use equality secondary index queries that return a small number of records, you may see a latency increase in server releases 6.0-6.2. The inline-short-queries configuration option provides a partial fix in server 6.3, and a more advanced fix is scheduled for server 6.4.
    • If your secondary index query only returns 0 records or 1 record, meaning that it is acting as a unique index, you should consider converting such a query to a get/exists operation by creating a self-managed reverse index (lookup table).
  • Spark Connector version 3.5 starts using batch writes when possible, a feature which was introduced in Aerospike server version 6.0. Consult the Spark Connector rate limiting documentation before you upgrade the server. Pay attention to throttling write throughput, and use Spark Connector 3.5.5 or later, which fixes throttling behavior to conform to the aerospike.transaction.rate.
  • See Known issues for 6.3.0.0
