Fdw.Services.EtlMappers.Pooled

Zero-allocation ETL row mapper using dictionary pooling.

Overview

This package provides a high-performance ETL row mapper implementation that eliminates per-row dictionary allocations by using an object pool. The PooledDictionaryMapper pre-computes field ordinals during initialization and reuses dictionaries via a thread-safe DictionaryPool, achieving zero estimated allocations per row after warmup. This is the default mapper type registered with EtlRowMapperProvider.

Installation

<PackageReference Include="Fdw.Services.EtlMappers.Pooled" Version="x.y.z" />

Key Types

  • PooledDictionaryMapper - IEtlRowMapper implementation with zero allocations per row
  • PooledDictionaryMapperType - TypeOption registered as "Pooled" in EtlRowMapperTypes
  • PooledDictionaryMapperFactory - Factory for creating PooledDictionaryMapper instances
  • PooledDictionaryMapperConfiguration - Configuration with pool size and dictionary size limits
  • DictionaryPool - Thread-safe ConcurrentBag-based dictionary pool
  • RowMappingContext - Pre-computed field ordinals and names cached per read operation

Usage

// Automatic registration via EtlRowMapperTypes (default mapper type)
EtlRowMapperTypes.Configure(services, configuration, loggerFactory);
EtlRowMapperTypes.Register(services, loggerFactory);

// Configuration in appsettings.json
// "EtlMappers:Pooled": { "MaxPoolSize": 1000, "MaxDictionarySize": 100 }
