• Updated HeartbeatHandlerGroup to return Context alongside HeartbeatResponse.
• Added current_node_info to Context for tracking node information.
• Implemented on_node_disconnect in Context to handle node disconnection events, specifically for Frontend roles.
• Adjusted register_pusher function to return PusherId directly.
• Updated tests to accommodate changes in Context structure.
* fix/frontend-node-state: Refactor Heartbeat Handler Context Management
Refactored the HeartbeatHandlerGroup::handle method to use a mutable reference for Context instead of passing it by value. This change simplifies the
context management by eliminating the need to return the context with the response. Updated the Metasrv implementation to align with this new context
handling approach, improving code clarity and reducing unnecessary context cloning.
* revert: clean cluster info on disconnect
* fix/frontend-node-state: Add Frontend Expiry Listener and Update NodeInfoKey Conversion
• Introduced FrontendExpiryListener to manage the expiration of frontend nodes, including its integration with leadership change notifications.
• Modified NodeInfoKey conversion to use references, enhancing efficiency and consistency across the codebase.
• Updated collect_cluster_info_handler and metasrv to incorporate the new listener and conversion changes.
• Added frontend_expiry module to the project structure for better organization and maintainability.
* chore: add config for node expiry
* add some doc
* fix: clippy
* fix/frontend-node-state:
### Refactor Node Expiry Handling
- **Configuration Update**: Removed `node_expiry_tick` from `metasrv.example.toml` and `MetasrvOptions` in `metasrv.rs`.
- **Module Renaming**: Renamed `frontend_expiry.rs` to `node_expiry_listener.rs` and updated references in `lib.rs`.
- **Code Refactoring**: Replaced `FrontendExpiryListener` with `NodeExpiryListener` in `node_expiry_listener.rs` and `metasrv.rs`, removing the tick interval and adjusting logic to use a fixed 60-second interval for node expiry checks.
* fix/frontend-node-state:
Improve logging in `node_expiry_listener.rs`
- Enhanced warning message to include peer information when an unrecognized node info key is encountered in `node_expiry_listener.rs`.
* docs: update config docs
* fix/frontend-node-state:
**Refactor Context Handling in Heartbeat Services**
- Updated `HeartbeatHandlerGroup` in `handler.rs` to pass `Context` by value instead of by mutable reference, allowing for more flexible context
management.
- Modified `Metasrv` implementation in `heartbeat.rs` to clone `Context` when passing to `handle` method, ensuring thread safety and consistency in
asynchronous operations.
* fix/reject-ddl-in-follower-metasrv:
Add leader check and logging for gRPC requests in `procedure.rs`
- Implemented leader verification for `query_procedure_state`, `ddl`, and `procedure_details` gRPC requests in `procedure.rs`.
- Added logging with `warn` for requests reaching a non-leader node.
- Introduced `ResponseHeader` and `Error::is_not_leader()` to handle non-leader responses.
* fix/reject-ddl-in-follower-metasrv:
Improve leader address handling in `heartbeat.rs`
- Refactor leader address retrieval by renaming `leader` to `leader_addr` for clarity.
- Update `make_client` function to use a reference to `leader_addr`.
- Enhance logging to include the leader address in the success message for creating a heartbeat stream.
* fmt
* fix/reject-ddl-in-follower-metasrv:
**Enhance Leader Check in `procedure.rs`**
- Updated the leader verification logic in `procedure.rs` to return a failed `MigrateRegionResponse` when the server is not the leader.
- Added logging to warn when a migrate request is received by a non-leader server.

* fix/avoid-suppress-manual-compaction:
**Refactor Compaction Logic**
- Removed `PendingCompaction` struct and integrated its functionality directly into `CompactionStatus` in `compaction.rs`.
- Simplified waiter management by consolidating waiter handling logic into `CompactionStatus`.
- Updated `CompactionRequest` creation to directly handle waiters without intermediate structures.
- Adjusted test cases in `compaction.rs` to align with the new waiter management approach.
(cherry picked from commit 87e2d1c2cc9bd82c02991d22e429bef25c5ee348)
* fix/avoid-suppress-manual-compaction:
### Add Support for Manual Compaction Requests
- **Compaction Logic Enhancements**:
- Updated `CompactionScheduler` in `compaction.rs` to handle manual compaction requests using `Options::StrictWindow`.
- Introduced `PendingCompaction` struct to manage pending manual compaction requests.
- Added logic to reschedule manual compaction requests once the current compaction task is completed.
- **Testing**:
- Added `test_manual_compaction_when_compaction_in_progress` to verify the handling of manual compaction requests during ongoing compaction processes.
These changes enhance the compaction scheduling mechanism by allowing manual compaction requests to be queued and processed efficiently.
(cherry picked from commit bc38ed0f2f8ba2c4690e0d0e251aeb2acce308ca)
* chore: fix conflicts
* fix/avoid-suppress-manual-compaction:
### Add Error Handling for Manual Compaction Override
- **`compaction.rs`**: Enhanced the `set_pending_request` method to handle manual compaction overrides by sending an error to the waiter if a previous request exists.
- **`error.rs`**: Introduced a new error variant `ManualCompactionOverride` to represent manual compaction being overridden, and mapped it to the `Cancelled` status code.
* fix: format
* fix/avoid-suppress-manual-compaction:
**Add Error Handling for Pending Compaction Requests**
- Enhanced error handling in `compaction.rs` by adding logic to handle errors for pending compaction requests.
- Introduced a mechanism to send errors using `waiter.send` when a pending compaction request fails, ensuring proper error propagation and context with `CompactRegionSnafu`.
* fix/avoid-suppress-manual-compaction:
**Fix Typo and Simplify Code Logic in `compaction.rs`**
- Corrected a typo in the license comment from "langucage" to "language".
- Simplified the logic for handling `pending_compaction` in `CompactionStatus` by removing unnecessary pattern matching and directly accessing `waiter`.

**GreptimeDB** is an open-source time-series database focusing on efficiency, scalability, and analytical capabilities.
**GreptimeDB** is an open-source, cloud-native database purpose-built for the unified collection and analysis of observability data (metrics, logs, and traces). Whether you’re operating on the edge, in the cloud, or across hybrid environments, GreptimeDB empowers real-time insights at massive scale — all in one system.
Designed to work on infrastructure of the cloud era, GreptimeDB benefits users with its elasticity and commodity storage, offering a fast and cost-effective **alternative to InfluxDB** and a **long-term storage for Prometheus**.
## Why GreptimeDB
## Features
Our core developers have been building time-series data platforms for years. Based on our best-practices, GreptimeDB is born to give you:
| Feature | Description |
| --------- | ----------- |
| [Unified Observability Data](https://docs.greptime.com/user-guide/concepts/why-greptimedb) | Store metrics, logs, and traces as timestamped, contextual wide events. Query via [SQL](https://docs.greptime.com/user-guide/query-data/sql), [PromQL](https://docs.greptime.com/user-guide/query-data/promql), and [streaming](https://docs.greptime.com/user-guide/flow-computation/overview). |
| [High Performance & Cost Effective](https://docs.greptime.com/user-guide/manage-data/data-index) | Written in Rust, with a distributed query engine, [rich indexing](https://docs.greptime.com/user-guide/manage-data/data-index), and optimized columnar storage, delivering sub-second responses at PB scale. |
| [Cloud-Native Architecture](https://docs.greptime.com/user-guide/concepts/architecture) | Designed for [Kubernetes](https://docs.greptime.com/user-guide/deployments/deploy-on-kubernetes/greptimedb-operator-management), with compute/storage separation, native object storage (AWS S3, Azure Blob, etc.) and seamless cross-cloud access. |
| [Developer-Friendly](https://docs.greptime.com/user-guide/protocols/overview) | Access via SQL/PromQL interfaces, REST API, MySQL/PostgreSQL protocols, and popular ingestion [protocols](https://docs.greptime.com/user-guide/protocols/overview). |
| [Flexible Deployment](https://docs.greptime.com/user-guide/deployments/overview) | Deploy anywhere: edge (including ARM/[Android](https://docs.greptime.com/user-guide/deployments/run-on-android)) or cloud, with unified APIs and efficient data sync. |
* **Easy horizontal scaling**

Seamless scalability from a standalone binary at edge to a robust, highly available distributed cluster in cloud, with a transparent experience for both developers and administrators.
Fully open-source distributed cluster architecture that harnesses the power of cloud-native elastic computing resources.
## Architecture
***Performance and Cost-effective**
*Read the [architecture](https://docs.greptime.com/contributor-guide/overview/#architecture) document.
* [DeepWiki](https://deepwiki.com/GreptimeTeam/greptimedb/1-overview) provides an in-depth look at GreptimeDB:
Flexible indexing capabilities and distributed, parallel-processing query engine, tackling high cardinality issues down. Optimized columnar layout for handling time-series data; compacted, compressed, and stored on various storage backends, particularly cloud object storage with 50x cost efficiency.
<imgalt="GreptimeDB System Overview"src="docs/architecture.png">
* **Compatible with InfluxDB, Prometheus and more protocols**
Widely adopted database protocols and APIs, including MySQL, PostgreSQL, and Prometheus Remote Storage, etc. [Read more](https://docs.greptime.com/user-guide/clients/overview).
*Python toolchain (optional): Required only if built with PyO3 backend. More detail for compiling with PyO3 can be found in its [documentation](https://pyo3.rs/v0.18.1/building_and_distribution#configuring-the-python-version).
*C/C++ building essentials, including `gcc`/`g++`/`autoconf` and glibc library (eg. `libc6-dev` on Ubuntu and `glibc-devel` on Fedora)
* Python toolchain (optional): Required only if using some test scripts.

The wal benchmarker serves to evaluate the performance of GreptimeDB's Write-Ahead Log (WAL) component. It meticulously assesses the read/write performance of the WAL under diverse workloads generated by the benchmarker.
### How to use
To compile the benchmarker, navigate to the `greptimedb/benchmarks` directory and execute `cargo build --release`. Subsequently, you'll find the compiled target located at `greptimedb/target/release/wal_bench`.
The `./wal_bench -h` command reveals numerous arguments that the target accepts. Among these, a notable one is the `cfg-file` argument. By utilizing a configuration file in the TOML format, you can bypass the need to repeatedly specify cumbersome arguments.
