If you use equality secondary index queries that return a small number of records, you may see a latency increase in Database 6..0-6.2. The inline-short-queries configuration option provides a partial fix in Database 6.3, and a more advanced fix is scheduled for Database 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 Database 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.
