Enum CompressionStrategy 

pub enum CompressionStrategy {
    None,
    Page,
    Row,
    Columnstore,
    ColumnstoreArchive,
    Lz4,
    Zstd {
        level: Option<u8>,
    },
    Snappy,
}

Compression strategy for a materialized table.

Platform renderers translate these variants into the appropriate dialect-native WITH (DATA_COMPRESSION = ...), USING DELTA, or CODEC(...) syntax.

Variants

None

No compression applied.

Page

SQL Server page-level compression.

Row

SQL Server row-level compression.

Columnstore

Columnstore compression (columnar layout; SQL Server, Synapse, Azure Fabric).

ColumnstoreArchive

Columnstore archival compression (higher ratio, slower scans).

Lz4

LZ4 block compression (Delta Lake, ClickHouse).

Zstd

Zstd compression (Delta Lake, ClickHouse, DuckDB).

Fields

level: Option<u8>

Compression level (1 = fastest, higher = smaller; dialect-specific range).

Snappy

Snappy block compression (Parquet, Delta Lake).
