Struct SSTableWriterConfig 

pub struct SSTableWriterConfig {
    pub compression_level: CompressionLevel,

SSTable writer configuration

Fields

compression_level: CompressionLevel

Compression level (1-22, higher = better compression but slower)

use_dictionary: bool

Whether to train and use a dictionary for compression

dict_size: usize

Dictionary size in bytes (default 64KB)

use_bloom_filter: bool

Whether to build a bloom filter

bloom_bits_per_key: usize

Bloom filter bits per key (default 10 = ~1% false positive rate)

Implementations

impl SSTableWriterConfig

pub fn from_optimization(optimization: IndexOptimization) -> Self

Create config from IndexOptimization mode

pub fn fast() -> Self

Fast configuration - prioritize write speed over compression

pub fn max_compression() -> Self

Maximum compression configuration - prioritize size over speed
