Datafication.Storage.Velocity
Disk-backed columnar storage with SIMD-accelerated queries for large-scale DataBlocks.
Key Features
- DFC Columnar Storage: Segmented file format optimized for analytics
- Built-in Row IDs: O(1) updates and deletes via VelocityRowId
- Full CRUD Support: Update and delete operations without rebuilding
- Optional Primary Keys: Business-friendly key lookups when needed
- Deferred Execution: Query plan optimization for single-pass efficiency
- SIMD Acceleration: 10-30x faster window functions and computations
- Automatic Compaction: Background or on-demand storage optimization
- LZ4 Compression: Reduced storage footprint
Installation
dotnet add package Datafication.Storage.Velocity
Quick Start
using Datafication.Storage.Velocity;
// Create a VelocityDataBlock with primary key
var velocityBlock = VelocityDataBlock.CreateEnterprise(
"data/orders.dfc",
primaryKeyColumn: "OrderId"
);
// Save existing DataBlock to DFC storage
var velocityBlock = await VelocityDataBlock.SaveAsync(
"data/products.dfc",
dataBlock,
new VelocityOptions { PrimaryKeyColumn = "ProductId" }
);
// Query with deferred execution
var result = velocityBlock
.Where("Category", "Electronics")
.Where("Price", 100.0, ComparisonOperator.LessThan)
.Select("ProductName", "Price")
.Sort(SortDirection.Ascending, "Price")
.Execute();
