tigerbeetle-node - npm Package Versions

TigerBeetle 0.16.43

Released: 2025-05-30

This release includes the tigerbeetle recover subcommand, which can be used to safely recover a replica that is permanantly lost.

Additionally, it includes Change Data Capture (CDC) support to stream TigerBeetle state to Advanced Message Queuing Protocol (AMQP) targets, such as RabbitMQ and other compatible brokers.

Check out the documentation to learn about how to use CDC and tigerbeetle recover!

Safety And Performance

• #2996

  Add the tigerbeetle recover subcommand, to safely recover a replica that is permanantly lost (e.g. if the SSD fails).

  Earlier, the only way to recover a permanantly lost replica was using the tigerbeetle format command. Howerver, this was unsafe, as a newly-formatted replica may nack prepares which its previous incarnation acked -- a correctness bug.

• #2880

  Implement an adaptive replication routing protocol to handle changes in network topology.

  To select the best route, primary uses outcome-focused explore-exploit approach. Every once in a while, the primary tries an alternative route, and replaces the current route if the alternative provides better replication latency.

• #2970, #3002

  Replica pulls messages from the MessageBus, as opposed to the MessageBus pushing messages.

  Earlier, replicas had to process every message that the bus pushed. This could lead to messages being dropped due to lack of available disk read/write IOPs. Now, a replica can "suspend" certain messages and return to them later when it has enough IOPs.

Features

• #2917

  CDC support to stream TigerBeetle state to AMQP targets, such as RabbitMQ and other compatible brokers.

  We implement the AMQP 0.9.1 specification instead of AMQP 1.0 as it is simpler and more widely supported (e.g., RabbitMQ only recently added native AMQP 1.0 support).

• #2957

  Improved latency and throughput in prepare repair operations.

Internals

• #2967

  Make the Quick Start page more direct by showing only the installation instructions for Linux by default, with Windows and macOS hidden behind click-to-expand sections.

TigerBeetle 0.16.40

Released: 2025-05-09

Safety And Performance

• #2959

  Fix AOF unflushed assertion.

• #2950

  Decouple prepare repair from header breaks. This helps a replica repair faster, and prevents a case where we would request a prepare only to discard it when it arrives.

• #2945, #2961

  Bump default journal write iops. Previously we were inadvertently throttling repair by not allocating enough.

• #2944

  Primary now broadcasts start_view message on checkpoint durability. This will help syncing replicas update to the latest sync target as early as possible.

• #2952

  Add assert to check return value of next_batch_of_block_requests.

Features

• #2943, #2949, #2951

  Improve logging, especially of lagging replicas.

Internals

• #2937

  Add subcommand to git-review to send review comments as a email.

• #2926

  Add subcommand to git-review to split suggested code changes out of a review commit.

• #2940

  Speed up fuzz smoke tests.

• #2941

  Improve memory usage of tests 10x and test runtime 10x.

• #2936

  Add arbitrary debug output to CFO seeds.

• #2931

  Fix for multiple CFO branches on same commit.

• #2964

  Reduce closed loop replication quorum from n to n-1.

TigerBeetle 0.16.39

Released: 2025-05-02

Heads up, we are changing our release process! From this point on, a TigerBeetle release is tagged on Friday, spends a weekend on the CFO fleet, and is published on Monday. In other words, you'll still be getting a new release every Monday, but the date of the release will be set to Friday. This setup allows extra time for fuzzers to find problems in the specific commit we are trying to release.

Safety And Performance

• #2928

  Continuously fuzz the release branch, in addition to the main branch and the pull requests.

• #2923

  Eagerly deinitialize clients upon eviction, to proactively sever TCP connections to replicas.

Features

• #2679

  Add an initial Rust client. Note that it is not published to crates.io yet.

Internals

• #2906

  Reduce verbosity when running full CI suite locally.

Released: 2025-04-14

Safety And Performance

• #2891

  Fix journal disjoint-buffer assertion.

TigerBeetle 0.16.35

Released: 2025-04-07

Please note that after #2787, which adds batching support for all operations, the batch_max limit has changed from 8190 to 8189 accounts/transfers per batch.

Safety And Performance

• #2787

  Add support for batching multiple independent requests of the same operation within a single VSR message, amortizing network and consensus costs.

  Earlier, we batched only create_accounts and create_transfers. Now, we can batch any operation!

Internals

• #2878

  Use TigerBeetle's time abstraction as opposed to raw OS time in the tracer.

• #2881

  Allow custom network packet delay functions in the VOPR. This allows us to simulate latencies for different network topologies, for example the ring/star topology.

• #2866, #2874

  Fix a VOPR false positive wherein we were accessing a crashed replica's uninitialized memory.

• #2869

  Improve error thrown when an invalid --account/transfer-batch-size is passed to the benchmark CLI.

• #2876, #2877

  Minor refactors to VSR and VOPR.

  Fixes and improvemenents in the documentation.
