* feat/bridge-bulk-insert: ## Implement Bulk Insert and Update Dependencies - **Bulk Insert Implementation**: Added `handle_bulk_inserts` method in `src/operator/src/bulk_insert.rs` to manage bulk insert requests using `FlightDecoder` and `FlightData`. - **Dependency Updates**: Updated `Cargo.lock` and `Cargo.toml` to use the latest revision of `greptime-proto` and added new dependencies like `arrow`, `arrow-ipc`, `bytes`, and `prost`. - **gRPC Enhancements**: Modified `put_record_batch` method in `src/frontend/src/instance/grpc.rs` and `src/servers/src/grpc/flight.rs` to handle `FlightData` instead of `RawRecordBatch`. - **Error Handling**: Added new error types in `src/operator/src/error.rs` for handling Arrow operations and decoding flight data. - **Miscellaneous**: Updated `src/operator/src/insert.rs` to expose `partition_manager` and `node_manager` as public fields. * feat/bridge-bulk-insert: - **Update `greptime-proto` Dependency**: Updated the `greptime-proto` dependency to a new revision in `Cargo.lock` and `Cargo.toml`. - **Refactor gRPC Query Handling**: Removed `RawRecordBatch` usage from `grpc.rs`, `flight.rs`, `greptime_handler.rs`, and test files, simplifying the gRPC query handling. - **Enhance Bulk Insert Logic**: Improved bulk insert logic in `bulk_insert.rs` and `region_request.rs` by using `FlightDecoder` and `BooleanArray` for better performance and clarity. - **Add `common-grpc` Dependency**: Added `common-grpc` as a workspace dependency in `store-api/Cargo.toml` to support gRPC functionalities. * fix: clippy * fix schema serialization * feat/bridge-bulk-insert: Add error handling for encoding/decoding in `metadata.rs` and `region_request.rs` - Introduced new error variants `FlightCodec` and `Prost` in `MetadataError` to handle encoding/decoding failures in `metadata.rs`. - Updated `make_region_bulk_inserts` function in `region_request.rs` to use `context` for error handling with `ProstSnafu` and `FlightCodecSnafu`. - Enhanced error handling for `FlightData` decoding and `filter_record_batch` operations. * fix: test * refactor: rename * allow empty app_metadata in FlightData * feat/bridge-bulk-insert: - **Remove Logging**: Removed unnecessary logging of affected rows in `region_server.rs`. - **Error Handling Enhancement**: Improved error handling in `bulk_insert.rs` by adding context to `split_record_batch` and handling single datanode fast path. - **Error Enum Cleanup**: Removed unused `Arrow` error variant from `error.rs`. * fix: standalone test * feat/bridge-bulk-insert: ### Enhance Bulk Insert Handling and Metadata Management - **`lib.rs`**: Enabled the `result_flattening` feature for improved error handling. - **`request.rs`**: Made `name_to_index` and `has_null` fields public in `WriteRequest` for better accessibility. - **`handle_bulk_insert.rs`**: - Added `handle_record_batch` function to streamline processing of bulk insert payloads. - Improved error handling and task management for bulk insert operations. - Updated `region_metadata_to_column_schema` to return both column schemas and a name-to-index map for efficient data access. * feat/bridge-bulk-insert: - **Refactor `handle_bulk_insert.rs`:** - Replaced `handle_record_batch` with `handle_payload` for handling payloads. - Modified the fast path to use `common_runtime::spawn_global` for asynchronous task execution. - **Optimize `multi_dim.rs`:** - Added a fast path for single-region scenarios in `MultiDimPartitionRule::partition_record_batch`. * feat/bridge-bulk-insert: - **Update `greptime-proto` Dependency**: Updated the `greptime-proto` dependency to a new revision in both `Cargo.lock` and `Cargo.toml`. - **Optimize Memory Allocation**: Increased initial and builder capacities in `time_series.rs` to improve performance. - **Enhance Data Handling**: Modified `bulk_insert.rs` to use `Bytes` for efficient data handling. - **Improve Bulk Insert Logic**: Refined the bulk insert logic in `region_request.rs` to handle schema and payload data more effectively and optimize record batch filtering. - **String Handling Improvement**: Updated string conversion in `helper.rs` for better performance. * fix: clippy warnings * feat/bridge-bulk-insert: **Add Metrics and Improve Error Handling** - **Metrics Enhancements**: Introduced new metrics for bulk insert operations in `metrics.rs`, `bulk_insert.rs`, `greptime_handler.rs`, and `region_request.rs`. Added `HANDLE_BULK_INSERT_ELAPSED`, `BULK_REQUEST_MESSAGE_SIZE`, and `GRPC_BULK_INSERT_ELAPSED` histograms to monitor performance. - **Error Handling Improvements**: Removed unnecessary error handling in `handle_bulk_insert.rs` by eliminating redundant `let _ =` patterns. - **Dependency Updates**: Added `lazy_static` and `prometheus` to `Cargo.lock` and `Cargo.toml` for metrics support. - **Code Refactoring**: Simplified function calls in `region_server.rs` and `handle_bulk_insert.rs` for better readability. * chore: rebase main * chore: merge main

Introduction
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.
Features
| Feature | Description |
|---|---|
| Unified Observability Data | Store metrics, logs, and traces as timestamped, contextual wide events. Query via SQL, PromQL, and streaming. |
| High Performance & Cost Effective | Written in Rust, with a distributed query engine, rich indexing, and optimized columnar storage, delivering sub-second responses at PB scale. |
| Cloud-Native Architecture | Designed for Kubernetes, with compute/storage separation, native object storage (AWS S3, Azure Blob, etc.) and seamless cross-cloud access. |
| Developer-Friendly | Access via SQL/PromQL interfaces, REST API, MySQL/PostgreSQL protocols, and popular ingestion protocols. |
| Flexible Deployment | Deploy anywhere: edge (including ARM/Android) or cloud, with unified APIs and efficient data sync. |
