Aerospike Server Community Edition 4.9.0.3

Description

COMMUNITY EDITION USERS: Please use release 4.9.0.5 or newer in lieu of this version.

• ATTENTION: As of Aerospike Server version 4.9, expirations and evictions are disabled by default.
  • For expirations, nsup-period must be configured (new default is 0).
  • For evictions, the relevant high-water-disk-pct/high-water-memory-pct/mounts-high-water-pct must be configured (new defaults are 0).
  • For details refer to the Namespace Retention Configuration documentation.
• The Aerospike Server will not start If the value of default-ttl is non-zero and nsup-period is zero (the default).
• Record bins containing (collection data type) Ordered Lists that had operations performed under Aerospike Server versions 3.16.0.1-3.16.0.5 could be incompatible with server versions 4.6 or later due to stricter CDT validation. Also, Unordered Lists created with UDFs under server versions 3.16.0.1-4.5.3.15 could be marked as ordered, even if the application did not explicitly specify this, and would also be incompatible with server versions 4.6 or later. However induced, the incompatibility could also block XDR shipping. The Aerospike CDT Validation Tool is available in the Aerospike Tools 3.24.1 or newer release to identify -and if possible correct- such records. Aerospike recommends the validation tool be run on all namespaces that created or modified List CDTs under a pre-4.6 server. Refer to the Aerospike CDT Validation Tool documentation for steps necessary to run the tool and interpret the output.
• Support added for HyperLogLog (HLL) probabilistic data types.
  • Clusters connected using Cross Datacenter Replication (XDR) all clusters must have been upgraded to Aerospike Server 4.9 prior to using the HyperLogLog (HLL) data type.
  • Before downgrading from Aerospike Server 4.9 all HyperLogLog (HLL) bins must be removed by the application.
  • During the unlikely case of a downgrade the drives would need to be wiped. It is advised to review your Aerospike Server 4.9 environment prior to implementing the usage of HyperLogLog (HLL) data type bins.
• Added support for:
  • Partition-based basic scans, enabling accurate scans during migrations.
  • Added a max records option for sampling with basic scans.
  • Optional element creation in nested CDT operations.
• XDR, using ACL, in server versions between 4.1.0.1 and 4.3.0.6 cannot ship to this version. The simplest workaround is to avoid using those versions.
• When upgrading the Aerospike Server refer to the Special Upgrades documentation.
• Please reach out to your account representative if you are interested in Kerberos support.

New Features

• Enterprise & Community
  • [AER-6199] - (KVS) Added support for HyperLogLog (HLL) data types.
  • [AER-5474] - (SCAN) Basic scans now based on lists of partitions and/or digests sent by client.

Improvements

• Enterprise & Community
  • [AER-6184] - (KVS) Configuring any eviction threshold (e.g. high-water-memory-pct) to 0 disables that eviction threshold.
  • [AER-6186] - (KVS) Changed eviction-related high water percentage configuration defaults to 0, so that eviction is inactive by default.
  • [AER-6187] - (KVS) Changed default value of nsup-period to 0, and added namespace context configuration item allow-ttl-without-nsup to allow records with TTLs when nsup-period is 0.
  • [AER-6185] - (BATCH) Added service context configuration item batch-without-digests to exclude digests from batch responses.
  • [AER-6209] - (NETWORK) Ignore additional addresses for an interface once the limit (20) is reached.
  • [AER-6192] - (MIGRATION) Increased metadata batch size and maximum outstanding data size limit, to help performance across longer links.
  • [AER-6191] - (LOGGING) Changed warning message about failure to resolve a mount point to a detail level message.
  • [AER-6210] - (LOGGING) Changed default logging level to 'critical' for all contexts.
  • [AER-6116] - (STATS) Converted 'batch-index' histogram to tracked histogram.
  • [AER-6183] - (STATS) Added delay count to batch-index log ticker line.
• Enterprise Only
  • [AER-6205] - (KVS) Changed response (zlib) compression level to 1.
  • [AER-6208] - (KVS) Non-durable deletes will now ignore tombstones and return Not Found.
  • [AER-6158] - (TLS) Increased socket accept timeout to accommodate heartbeat across longer links.
  • [AER-6206] - (XDR) Changed (zlib) compression level to 1.

Bug Fixes

• Enterprise & Community
  • [AER-6211] - (KVS) Dynamically increasing both the system file descriptor limit and service context configuration item proto-fd-max to a value larger than the system limit at startup may cause an assert.
