Fields

root_path: PathBuf

Base directory where stream directories are created.

max_segment_size: u64

Soft limit for segment file size in bytes. A new segment is created if the current one exceeds this size. Default: 64 MB.

max_entries_per_segment: u64

Soft limit for number of entries per segment. A new segment is created if the current one exceeds this count. Default: u64::MAX (Disabled).

max_open_segments: usize

Maximum number of file descriptors to keep open simultaneously for writing. Uses an LRU policy to enforce this limit. Default: 50.

write_buffer_size: usize

Size of the in-memory write buffer before flushing to the OS kernel. Default: 64 KB.

read_buffer_size: usize

Size of the buffer used for reading/scanning files. Default: 128 KB.

block_cache_size: Option<u64>

Size of the Read Block Cache (in bytes). If None, caching is disabled. Default: None.

sync_mode: SyncMode

compression: CompressionType

read_strategy: ReadStrategy

on_corruption: CorruptionPolicy

min_compression_size: usize

If a batch is smaller than this (in bytes), it will be written uncompressed even if compression is enabled. Default: 1 KB.
