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 rowPooledDictionaryMapperType- TypeOption registered as "Pooled" in EtlRowMapperTypesPooledDictionaryMapperFactory- Factory for creating PooledDictionaryMapper instancesPooledDictionaryMapperConfiguration- Configuration with pool size and dictionary size limitsDictionaryPool- Thread-safe ConcurrentBag-based dictionary poolRowMappingContext- 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 }
