//! Bulk API Log Benchmark Example
//!
//! This benchmark demonstrates the LogTableDataProvider for generating synthetic log data
//! and measuring GreptimeDB bulk API ingestion performance.
//!
//! Note: The bulk API does not automatically create tables. You must manually create the table
//! before running this benchmark using the following schema:
//!
//! ```sql
//! CREATE TABLE IF NOT EXISTS `benchmark_logs` (
//!   `ts` TIMESTAMP(3) NOT NULL,
//!   `log_uid` STRING NULL,
//!   `log_message` STRING NULL,
//!   `log_level` STRING NULL,
//!   `host_id` STRING NULL,
//!   `host_name` STRING NULL,
//!   `service_id` STRING NULL,
//!   `service_name` STRING NULL,
//!   `container_id` STRING NULL,
//!   `container_name` STRING NULL,
//!   `pod_id` STRING NULL,
//!   `pod_name` STRING NULL,
//!   `cluster_id` STRING NULL,
//!   `cluster_name` STRING NULL,
//!   `trace_id` STRING NULL,
//!   `span_id` STRING NULL,
//!   `user_id` STRING NULL,
//!   `session_id` STRING NULL,
//!   `request_id` STRING NULL,
//!   `response_time_ms` BIGINT NULL,
//!   `log_source` STRING NULL,
//!   `version` STRING NULL,
//!   TIME INDEX (`ts`)
//! )
//! ENGINE=mito
//! WITH(
//!   append_mode = 'true',
//!   skip_wal = 'true'
//! );
//! ```
//!
//! Usage:
//!   cargo run --example bulk_api_log_benchmark --release
//!
//! Environment variables:
//!   GREPTIME_ENDPOINT - GreptimeDB endpoint (default: localhost:4001)
//!   GREPTIMEDB_DBNAME - Database name (default: public)  
//!   TABLE_ROW_COUNT   - Number of rows to generate (default: 1_000_000)
//!   BATCH_SIZE        - Batch size for ingestion (default: 64 * 1024)
//!   PARALLELISM       - Parallel requests (default: 8)
//!   COMPRESSION       - Enable compression (default: lz4)
