Full Changelog: v2.0.0-alpha.1...v2.0.0-alpha.2

Release Date: May 19, 2025

• New Major Release

• We are pleased to release the first alpha version of the next generation v2 for the Rust client.

• This version of the client comes with a major feature: async! This feature was started by Jonas Breuer, in his epic PR and fixed and extended by Aerospike. We would like to thank him for his amazing contribution. We also extend our gratitude to all others who also opened PRs and reported bugs and other issues.

• Please keep in mind that the API is still unstable and we WILL break it to enhance ergonomics, feature-set and the performance of the library. We invite the community to test drive the library and file tickets for bug reports or enhancement either on Github or with Aerospike support.

New Features

• Support async rust. You can use both tokio and async-std as features to enable the respective runtimes. tokio is the default.
• Support sync through blocking in the sync sub-crate.
• Support new batch protocol, allowing read, write, delete and udf operations. Use BatchOperation constructors. [CLIENT-2051]
• Support queries and scans not sending a fresh message header per partition in server v6+. [CLIENT-2321]
• Implement std::convert::TryFrom<aerospike::Value> for each variant. [CLIENT-2320]
• Support boolean particle type. [CLIENT-2099]
• Support New Scan/Query wire protocol.
• Replace error-chain with a custom implementation. We still use thiserror's macros internally (To be removed in the future.)
• Support for Replica policies, including PreferRack policy.
• Removes lifetimes that were due to &str, replacing most of them with String.

Bug Fixes

• Fixed various bugs in messagepack encoding.
• Fixed large integers packing when encoding to messagepack.
• Fixed Float serialization.

Full Changelog: v1.3.0...v2.0.0-alpha.1

Release Date: May 01, 2023

• Minor feature release

New Features

• Support boolean particle type. [CLIENT-2099]
• Implement std::convert::TryFromaerospike::Value for each variant. Resolves #124. Refer to the mentioned ticket for the use case. [CLIENT-2320]
• Support queries and scans not sending a fresh message header per partition in server v6+. [CLIENT-2321]

Improvements

• Fix tests failing without the AEROSPIKE_HOSTS environment variable set. Now they use localhost by default.
• Fix a few compiler warnings and remove a few unused struct fields.

Bug Fixes

• Fixed large integers packing when encoding to messagepack. Thanks to Babur Makhmudov.
• Fixed Float serialization. Thanks to Jonas Breuer.

Full Changelog: v1.2.0...v1.3.0

Release Date: October 22, 2021

• Major Feature Release

New Features

• Support Aerospike server v5.6+ expressions in Operate API. Thanks to Jonas Breuer

Bug Fixes

• Fix for buffer size when using CDT contexts. Thanks to Jonas Breuer

Full Changelog: v1.1.0...v1.2.0

Release Date: October 12, 2021

• Minor fix release

• This version of the client drops support for the older server versions without changing the API.

• ScanPolicy.fail_on_cluster_change, ScanPolicy.scan_percent and BasePolicy.priority are deprecated for the Scan operations and will not be sent to the server. They remain in the API to avoid breaking the API.

New Features

• Support Aerospike server v5.6+ server authentication.
• Support Aerospike server v5.6+ Scan protocol for simple cases.

Full Changelog: v1.0.0...v1.1.0

Release Date: October 29, 2020

New Features

• BREAKING CHANGE: Replace predicate expressions with new Aerospike Expression filters. Aerospike Expression filters give access to the full data type APIs (List, Map, Bit, HyperLogLog, Geospatial) and expanded metadata based filtering, to increase the power of filters in selecting records. This feature requires server version 5.2.0.4 or later. See API Changes for details. (#80) Thanks to @jonas32!
• Support operations for the HyperLogLog (HLL) data type. (#89) Thanks to @jonas32!
• Serde Serializers for Record and Value objects. (#85) Thanks to @jonas32!

Bug Fixes

• Client.is_connected() returns true even after client.close() is called. (#87)

Full Changelog: v0.6.0...v1.0.0

Release Date: September 11, 2020

New Features

• Big update for operations: (#79) Thanks to @jonas32!
  • Added operation contexts for nested operations.
  • Added missing list operations, list policies, and ordered lists.
  • Added missing map operations.
  • Added bitwise operations.

⚠️ Caution
This is a breaking change. The policy and return types for Lists require additional parameters for the CDT op functions.

Bug Fixes

• Shrink connection buffers to avoid unbounded memory allocation. (#83) Thanks to @soro!

Updates

• Restrict Travis CI tests to stable/beta/nightly. (#84)

Full Changelog: v0.5.0...v0.6.0
