Aerospike Database Release Notes 6.1.0.13

April 06, 2023

This release is a hotfix for Aerospike server 6.1.

Bug Fixes

Enterprise, Federal & Community
- [AER-6621] - (LOGGING) CDT operations resulting in "normal" errors ELEMENT_NOT_FOUND & ELEMENT_EXISTS are logged as warnings instead of detail.
- [AER-6623] - (QUERY) For AP namespaces, queries may miss records during certain migration scenarios.
Enterprise & Federal Only
- [AER-6620] - (KVS) For index-type flash namespaces, configuring index-stage-size 4G or larger may cause assertions or other bad symptoms on warm restart.
- [AER-6622] - (SINDEX) When cool restarting data-in-memory namespaces, a secondary-indexed record which expires after startup but before being loaded into memory will assert.

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.
There is a possibility of partial de-duplicate (repeated records) in secondary index query (SI query) responses for SI queries that use list or map type secondary indexes. Any record that satisfies such a query at least once will be included, but it is possible and normal to see a record more than once.
