SSTable writer configuration

Fields

block_size: SSTableBlockSize

Target uncompressed entry bytes per block; default 16 KiB.

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
