Configuration for file-based event log

Fields

base_dir: PathBuf

Base directory for event log files

max_file_size: u64

Maximum size of a single log file before rotation (bytes)

write_buffer_size: usize

Buffer size for writes

batch_buffer_size: usize

Maximum size for batch write buffer (bytes)

max_event_size: usize

Maximum size of a single event payload (bytes)

max_batch_bytes: usize

Maximum total size for a single append batch (bytes)

flush_on_append: bool

Whether to flush the write buffer after each append (default: true).

When true, every append_with_id / append_events_batch call flushes the BufWriter, ensuring data reaches the OS page cache immediately. Set to false for maximum throughput at the cost of losing in-flight buffered events on a process crash (the OS-level file won’t be corrupted, but un-flushed events will be lost).
