## Bug Fixes

-   Enterprise, Federal & Community
    
    -   AER-6662- (SMD) Internally retried SMD events are not thread safe at shutdown or with certain info commands.
-   Enterprise & Federal Only
    
    -   AER-6663 - (SINDEX) Secondary index statistics may be incorrect on a warm restart following a shutdown which occurred while dropping the secondary index.
        
    -   AER-6664 - (SINDEX) When cool restarting [`data-in-memory`](https://aerospike.com/docs/database/reference/config#namespace__data-in-memory) namespaces, a secondary-indexed record which expires after startup but before being loaded into memory will not be removed from the secondary index.
        

## Known Issues

-   If you use `equality` secondary index queries that return a small number of records, you may see a latency increase in Database 6.0.0-6.2.0. The [`inline-short-queries`](https://aerospike.com/docs/database/reference/config#namespace__inline-short-queries) configuration option provides a partial fix in Database 6.3.0, and a more advanced fix is scheduled for Database 6.4.0.
    
-   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 6.0.0. Consult the Spark Connector [rate limiting documentation](https://aerospike.com/docs/connectors/spark/rate-limiting#set-rate-quotas-in-the-spark-application) before you upgrade the database. 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.
