### Enhance Series Initialization and Capacity Management
- **`simple_bulk_memtable.rs`**: Updated the `Series` initialization to use `with_capacity` with a specified capacity of 8192, improving memory management.
- **`time_series.rs`**: Introduced `with_capacity` method in `Series` to allow custom initial capacity for `ValueBuilder`. Adjusted `INITIAL_BUILDER_CAPACITY` to 16 for more efficient memory usage. Added a new `new` method to maintain backward compatibility.

### Commit Message
#### Refactor Prometheus Validation Mode
- **Replace `is_strict_mode` with `PromValidationMode` Enum:**
- Updated `HttpOptions` and related structures to use `PromValidationMode` enum instead of the boolean `is_strict_mode`.
- Modified functions and tests to accommodate the new enum, ensuring flexible validation modes (`Strict`, `Lossy`, `Unchecked`).
- Affected files: `server.rs`, `prom_decode.rs`, `http.rs`, `prom_store.rs`, `prom_row_builder.rs`, `proto.rs`, `prom_store_test.rs`, `test_util.rs`, `http.rs`.
- **Enhance UTF-8 String Decoding:**
- Introduced `decode_string` function to handle UTF-8 string decoding based on the selected `PromValidationMode`.
- Affected files: `proto.rs`, `prom_row_builder.rs`.
This refactor improves the flexibility and clarity of Prometheus request handling by allowing different validation strategies.
* feat/lossy-string-validation-in-prom-remote-write:
- **Add Prometheus Validation Mode Configuration:**
- Updated `config/config.md`, `config/frontend.example.toml`, and `config/standalone.example.toml` to include `http.prom_validation_mode` setting for Prometheus remote write requests.
- **Enhance Benchmarking for Prometheus Requests:**
- Modified `src/servers/benches/prom_decode.rs` to benchmark different Prometheus validation modes (`Strict`, `Lossy`, `Unchecked`).
- **Implement and Test String Decoding:**
- Added `decode_string` function and comprehensive tests in `src/servers/src/proto.rs` to handle string decoding with different validation modes.
* feat/lossy-string-validation-in-prom-remote-write:
### Add Histogram Buckets to Metrics
- **Files Modified**: `src/servers/src/metrics.rs`
- **Key Changes**:
- Added specific histogram buckets to `METRIC_MYSQL_QUERY_TIMER`, `METRIC_POSTGRES_QUERY_TIMER`, and `METRIC_SERVER_GRPC_PROM_REQUEST_TIMER` to enhance granularity in query elapsed time metrics.
* feat/lossy-string-validation-in-prom-remote-write:
### Update Prometheus Validation Mode Default
- **Config Documentation**: Updated the default description for `http.prom_validation_mode` to indicate that "strict" is the default option in `config.md`, `frontend.example.toml`, and `standalone.example.toml`.
- **HTTP Server Implementation**: Changed the default `prom_validation_mode` to `PromValidationMode::Strict` in `src/servers/src/http.rs`.
* feat/lossy-string-validation-in-prom-remote-write:
**Commit Message:**
Update Prometheus Validation Mode to Strict
- Changed `http.prom_validation_mode` from `unchecked` to `strict` in `config.md`, `frontend.example.toml`, and
`standalone.example.toml` to enforce strict validation of Prometheus remote write requests.

### Refactor: Simplify Data Handling in LogStore Implementations
- **`kafka/log_store.rs`, `raft_engine/log_store.rs`, `wal.rs`, `raw_entry_reader.rs`, `logstore.rs`:**
- Refactored `entry` and `build_entry` functions to accept `Vec<u8>` directly instead of `&mut Vec<u8>`.
- Removed usage of `std::mem::take` for data handling, simplifying the code and improving readability.
- Updated test cases to align with the new function signatures.
* feat/bulk-wal:
### Add Support for Bulk WAL Entries and Flight Data Encoding
- **Add `raw_data` field to `BulkPart` and related structs**: Updated `BulkPart` and related structures in `src/mito2/src/memtable/bulk/part.rs`, `src/mito2/src/memtable/simple_bulk_memtable.rs`, `src/mito2/src/memtable/time_partition.rs`, `src/mito2/src/region_write_ctx.rs`,
`src/mito2/src/worker/handle_bulk_insert.rs`, and `src/store-api/src/region_request.rs` to include a new `raw_data` field for handling Arrow IPC data.
- **Implement Flight Data Encoding**: Added a new module `flight` in `src/common/test-util/src/flight.rs` to encode record batches to Flight data format.
- **Update `greptime-proto` dependency**: Changed the revision of the `greptime-proto` dependency in `Cargo.lock` and `Cargo.toml`.
- **Enhance WAL Writer and Tests**: Modified `src/mito2/src/wal.rs` and related test files to support bulk WAL entries and added tests for encoding and handling bulk data.
* feat/bulk-wal:
- **Update `greptime-proto` Dependency**: Updated the `greptime-proto` dependency to a new revision in `Cargo.lock` and `Cargo.toml`.
- **Add `common-grpc` Dependency**: Added `common-grpc` as a dependency in `Cargo.lock` and `src/mito2/Cargo.toml`.
- **Refactor `BulkPart` Structure**: Removed `num_rows` field and added `num_rows()` method in `src/mito2/src/memtable/bulk/part.rs`. Updated related usages in `src/mito2/src/memtable/simple_bulk_memtable.rs`, `src/mito2/src/memtable/time_partition.rs`, `src/mito2/src/memtable/time_series.rs`,
`src/mito2/src/region_write_ctx.rs`, and `src/mito2/src/worker/handle_bulk_insert.rs`.
- **Implement `TryFrom` and `From` for `BulkWalEntry`**: Added implementations for converting between `BulkPart` and `BulkWalEntry` in `src/mito2/src/memtable/bulk/part.rs`.
- **Handle Bulk Entries in Region Opener**: Added logic to process bulk entries in `src/mito2/src/region/opener.rs`.
- **Fix `BulkInsertRequest` Handling**: Corrected `region_id` handling in `src/operator/src/bulk_insert.rs` and `src/store-api/src/region_request.rs`.
- **Add Error Variant for `ConvertBulkWalEntry`**: Added a new error variant in `src/mito2/src/error.rs` for handling bulk WAL entry conversion errors.
* fix: ci
* feat/bulk-wal:
Add bulk write operation in `opener.rs`
- Enhanced the region write context by adding a call to `write_bulk()` after `write_memtable()` in `opener.rs`.
- This change aims to improve the efficiency of writing operations by enabling bulk writes.
* feat/bulk-wal:
Enhance error handling and metrics in `bulk_insert.rs`
- Updated `Inserter` to improve error handling by capturing the result of `datanode.handle(request)` and incrementing the `DIST_INGEST_ROW_COUNT` metric with the number of affected rows.
* feat/bulk-wal:
### Remove Encode Error Handling for WAL Entries
- **`error.rs`**: Removed the `EncodeWal` error variant and its associated handling.
- **`wal.rs`**: Eliminated the `entry_encode_buf` buffer and its usage for encoding WAL entries. Replaced with direct encoding to a vector using `encode_to_vec()`.
