LeanCorpus.Compression.Snappy

Use this package when you want fast stored-field compression with a speed and size profile similar to LZ4.

Enable Snappy compression

Install the core and codec packages:

dotnet add package LeanCorpus
dotnet add package LeanCorpus.Compression.Snappy

using Rowles.LeanCorpus.Codecs.StoredFields;
using Rowles.LeanCorpus.Compression.Snappy;
using Rowles.LeanCorpus.Index.Indexer;

SnappyCompression.Register();

var config = new IndexWriterConfig
{
    CompressionPolicy = FieldCompressionPolicy.Snappy
};

Use config when constructing the IndexWriter. The policy is stored in the segment header, so mixed-policy indices remain readable when every required codec is registered.

Note

Normal .NET applications also receive automatic module-initialiser registration. Calling Register() explicitly is harmless and makes startup intent visible.

Important

Native AOT applications should call SnappyCompression.Register() explicitly before opening or writing an index that uses Snappy. Confirm that all package assets required by the deployment target are published.

Choose Snappy when

compression and decompression latency are the main concern;
interoperability with an existing Snappy-oriented deployment matters;
a modest compression ratio is acceptable.

The core package already includes Deflate and Brotli. See stored-field compression for policy trade-offs and block-size guidance.
