Aerospike Database 7.0 Release Notes

November 15, 2023 | Download

New in this version

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

New storage engine for in-memory namespaces
- Unified write-block storage format
- Aerospike Enterprise Edition (EE) and Standard Edition (SE) store data in shared memory segments
- Fast restarts for EE and SE in-memory namespaces
- Compression available for in-memory namespaces
Default TTL can now be configured at set level
Secondary indexes can be built on the bytes data type (BLOBs)
See the detailed complete list of all new features

Server UDF subsystem upgraded to Lua version 5.4
Aerospike Tools 10.0
Removed limit on number of unique bin names per namespace
Increased the maximum number of sets per namespace to 4095
An optimization for data-in-memory namespaces with storage-backed persistence, where hot keys that remain exactly the same size between writes were written in-place, has been removed in Database 7.0 as part of AER-6666.
API changes
- The device_size and memory_size expressions are now deprecated. Use the new expression record_size instead.
- Developer API option to keep a CDT index on a per-bin basis is available for any storage engine
See Platform support and compatibility for all currently supported platforms

Before upgrading to 7.0, from pre-7.0, cluster-name must be set dynamically on all nodes in the pre-7.0 cluster.
index-type flash does not work with storage-engine pmem or storage-engine memory.
See configuration changes for namespace data storage and data retention.

Item	Action	Notes
`storage-engine` `memory`	added	new context supporting most of the `storage-engine` `device` configuration items
`data-size`	added	for `storage-engine` `memory`, only if there is no device/file backing (that is, “memory only”)

Item	Action	Notes
`memory-size`	removed	Starting with Database 7.1 use `indexes-memory-budget`
`stop-writes-pct`	removed	use `stop-writes-sys-memory-pct`
`data-in-memory`	removed	use `storage-engine` `memory`
`high-water-memory-pct`	removed
`commit-min-size`	removed

Item	Action
`bins`	removed

Aerospike shared memory tool (ASMT) now backs up storage-engine memory to and from shared memory (shmem).
Removed AQL truncate command. (Replaced with asadm manage command).

For full feature access in Database 7.0:

ID	Description
AER-6666	(STORAGE) Redesigned memory storage, including significant changes to configuration and statistics.
AER-6668	(KVS) The number of bin names per namespace is now unlimited.
AER-6669	(UDF) Upgraded Lua to version 5.4.
AER-6671	(STORAGE) Storage benchmark histograms may now be configured to use units of microseconds.
AER-6672	(KVS) Added set context configuration item ‘default-ttl’ to optionally specify a default ttl at the set level.
AER-6674	(KVS) Increased the maximum number of sets per namespace to 4095.
AER-6675	(UDF) Implemented record.size(), to replace the now-deprecated record.memory_size() and record.device_size() methods.
AER-6676	(EXPRESSIONS) Added a `record_size()` op, to replace the now-deprecated `device_size()` and `memory_size()` ops.
AER-6677	(CDT) Added support for persisting CDT indexes as specified per operation.
AER-6678	(CLUSTERING) It is now mandatory to set service context configuration item `cluster-name`.
AER-6679	(SINDEX) Added support for secondary indexes on “blob” type elements.
AER-6683	(UDF) Preserve the specific blob type of a bin when it is read and rewritten by a UDF.
AER-6685	(STORAGE) Removed storage context configuration item `commit-min-size`.
AER-6686	(CDT) If not already key-sorted, sort all maps written to the server.

Aerospike provides Maintenance and Support for 2 years (24 months) starting with Database release 6.3. See Platform support for details.
