commit ca58daba2837ae9c8f7a6242c453b091d4ebefb9 Author: Hubert Gruszecki <[email protected]> AuthorDate: Thu Jan 29 19:11:28 2026 +0100 fix(server): segments inherit topic's message_expiry instead of server default Segments created after server startup were using the server's default message_expiry (NeverExpire) rather than the topic's configured value, causing messages to never be cleaned up even when expiry was set. - Propagate topic's message_expiry to all segment creation sites - Move message_expiry config from [system.segment] to [system.topic] - Remove delete_oldest_segments toggle - Seal segments on rotation so is_expired() can evaluate them - Add comprehensive tests for time-based, size-based, and combined Closes #2629. --- Cargo.lock | 2 +- DEPENDENCIES.md | 2 +- core/bench/src/args/common.rs | 6 +- core/bench/src/args/examples.rs | 1 + core/bench/src/args/kinds/balanced/producer.rs | 10 +- .../kinds/balanced/producer_and_consumer_group.rs | 10 +- .../args/kinds/end_to_end/producing_consumer.rs | 10 +- .../kinds/end_to_end/producing_consumer_group.rs | 10 +- core/bench/src/args/kinds/pinned/producer.rs | 10 +- .../src/args/kinds/pinned/producer_and_consumer.rs | 10 +- core/bench/src/args/props.rs | 5 +- core/bench/src/benchmarks/benchmark.rs | 7 +- core/integration/tests/config_provider/mod.rs | 9 +- core/integration/tests/server/message_cleanup.rs | 124 +++ core/integration/tests/server/mod.rs | 1 + .../server/scenarios/message_cleanup_scenario.rs | 950 +++++++++++++++++++++ core/integration/tests/server/scenarios/mod.rs | 1 + core/integration/tests/server/specific.rs | 6 - core/server/Cargo.toml | 2 +- core/server/config.toml | 66 +- core/server/src/bootstrap.rs | 11 +- core/server/src/configs/defaults.rs | 3 +- core/server/src/configs/displays.rs | 8 +- core/server/src/configs/system.rs | 9 +- core/server/src/configs/validators.rs | 37 +- core/server/src/shard/system/messages.rs | 9 +- core/server/src/shard/system/partitions.rs | 6 +- core/server/src/shard/system/segments.rs | 27 +- .../src/shard/tasks/periodic/message_cleaner.rs | 216 +++-- core/server/src/streaming/segments/segment.rs | 31 +- 30 files changed, 1359 insertions(+), 240 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index fc1ce8c7f..cb294300d 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -8247,7 +8247,7 @@ dependencies = [ [[package]] name = "server" -version = "0.6.1-edge.6" +version = "0.6.1-edge.7" dependencies = [ "ahash 0.8.12", "anyhow", diff --git a/DEPENDENCIES.md b/DEPENDENCIES.md index b5861ebea..5c8193363 100644 --- a/DEPENDENCIES.md +++ b/DEPENDENCIES.md @@ -718,7 +718,7 @@ serde_with_macros: 3.16.1, "Apache-2.0 OR MIT", serde_yaml_ng: 0.10.0, "MIT", serial_test: 3.3.1, "MIT", serial_test_derive: 3.3.1, "MIT", -server: 0.6.1-edge.6, "Apache-2.0", +server: 0.6.1-edge.7, "Apache-2.0", sha1: 0.10.6, "Apache-2.0 OR MIT", sha2: 0.10.9, "Apache-2.0 OR MIT", sha3: 0.10.8, "Apache-2.0 OR MIT", diff --git a/core/bench/src/args/common.rs b/core/bench/src/args/common.rs index ebc54e48b..be983c209 100644 --- a/core/bench/src/args/common.rs +++ b/core/bench/src/args/common.rs @@ -30,7 +30,7 @@ use bench_report::benchmark_kind::BenchmarkKind; use bench_report::numeric_parameter::BenchmarkNumericParameter; use clap::error::ErrorKind; use clap::{CommandFactory, Parser}; -use iggy::prelude::{IggyByteSize, IggyDuration, TransportProtocol}; +use iggy::prelude::{IggyByteSize, IggyDuration, IggyExpiry, TransportProtocol}; use std::num::NonZeroU32; use std::str::FromStr; @@ -291,6 +291,10 @@ impl IggyBenchArgs { self.benchmark_kind.inner().max_topic_size() } + pub fn message_expiry(&self) -> IggyExpiry { + self.benchmark_kind.inner().message_expiry() + } + pub fn read_amplification(&self) -> Option<f32> { self.benchmark_kind.inner().read_amplification() } diff --git a/core/bench/src/args/examples.rs b/core/bench/src/args/examples.rs index 7a00929e5..ebd39ba91 100644 --- a/core/bench/src/args/examples.rs +++ b/core/bench/src/args/examples.rs @@ -68,6 +68,7 @@ const EXAMPLES: &str = r#"EXAMPLES: --producers (-c): Number of producers --consumers (-c): Number of consumers --max-topic-size (-T): Max topic size (e.g., "1GiB") + --message-expiry (-e): Message expiry time (e.g., "1s", "5min", "1h") Examples with detailed configuration: diff --git a/core/bench/src/args/kinds/balanced/producer.rs b/core/bench/src/args/kinds/balanced/producer.rs index 02a222288..3190fc9fd 100644 --- a/core/bench/src/args/kinds/balanced/producer.rs +++ b/core/bench/src/args/kinds/balanced/producer.rs @@ -26,7 +26,7 @@ use crate::args::{ transport::BenchmarkTransportCommand, }; use clap::{CommandFactory, Parser, error::ErrorKind}; -use iggy::prelude::IggyByteSize; +use iggy::prelude::{IggyByteSize, IggyExpiry}; use std::num::NonZeroU32; /// N producers sending to N separated stream-topic with single partition (one stream per one producer) @@ -50,6 +50,10 @@ pub struct BalancedProducerArgs { /// Max topic size in human readable format, e.g. "1GiB", "2MB", "1GiB".
