Aerospike Server Community Edition 8.1.2.0
New in this version
- Enhanced path expressions
- Operation projection added to queries
- Set index management
- Support for AlmaLinux 9 and 10
Enhanced path expressions
Enhanced the expression API to make path expressions easier to write.
Path expressions significantly enhance Aerospike's capability as a document store, simplifying the developer experience by offering native support for JSON-like models. Developers can effectively model data as a list of map elements and easily index, query, and retrieve data from those complex structures. When combined with index expressions, you can use path expressions to index and query data within deeply nested structures.
See Path expressions for details.
Operation projection in queries
Queries now accept the same bin projection, operations, and read expressions used in single-key and operate batched-commands. This unifies the developer API and eliminates the two-phase query and batch workaround.
- Use read operations (bin reads, collection data type (CDT) API and read expressions) in query projections.
- Apply path expressions in query projection, not only in the filter expression.
- Reduce bandwidth and latency by projecting only requested bins or values computed server-side.
- Projection of a list of bin-names remains supported for backward compatibility.
See Operation projection in queries for details.
Manage set indexes with info commands
You can create and delete set indexes using the same info commands as secondary indexes, with the sindex-admin privilege. With this change, you can manage set indexes on Aerospike Cloud, where the sys-admin role is not available to users.
- Create a set index – Use
sindex-createwithindextype=setand a required index name, namespace, and set. The equivalent command inasadmismanage sindex create INDEX-NAME ns NAMESPACE set SET. - Delete a set index – Use
sindex-deletewith the index name, namespace, and set. The sindex-admin privilege is required. - List indexes –
sindex-listandshow sindexinclude both secondary and set indexes. The output includes a mode column (secondaryordigest).
See Managing set indexes and Set index.
Deprecated: set-config / enable-index for set index lifecycle
Creating or removing set indexes via set-config (or asadm manage config) with enable-index is deprecated. Use sindex-create and sindex-delete instead. Deprecation warnings are logged when the config method is used. Backward compatibility is maintained: you can still use set-config/enable-index for existing workflows, but new set indexes should use sindex-create. See Managing set indexes and Special upgrades for upgrade guidance.
Control group (cgroup) memory tracking
The new cgroup-mem-tracking service configuration parameter enables control group (cgroup)-aware stop-writes memory calculations. When enabled, system_free_mem_kbytes and system_free_mem_pct report control group (cgroup)-aware values. The new host_free_mem_kbytes and host_free_mem_pct statistics always report host-level memory. Even when disabled, the server logs a warning if a control group (cgroup) memory limit is detected and less than 10% is available.
Query threads limit warning
The warning about exceeding query-threads-limit is now rate-limited through the ticker instead of emitted per query. Per-job failure warnings are demoted to detail level.
TLS CA hot-reload (Enterprise only)
The TLS refresh mechanism now monitors ca-file and ca-path for changes. When CA trust material changes, the SSL context is rebuilt and swapped, enabling CA rotation without a node restart.
XDR recovery drain on prole (Enterprise only)
Pending XDR recovery retry requests are now drained when a partition transitions to prole, preventing a possible invariant violation where a node could become master with more than MAX_IN_PROGRESS outstanding requests.
