Properties

DeferredCleanup

Deferred cleanup subsystem configuration for MVCC revision management.

public DeferredCleanupOptions DeferredCleanup { get; set; }

Property Value

DeferredCleanupOptions

Resources

Resource knobs for the engine subsystems: max concurrent transactions, WAL ring-buffer size, checkpoint cadence, and page-CRC policy.

public ResourceOptions Resources { get; set; }

Property Value

ResourceOptions

Remarks

Range-validated at DI resolution by the engine's options validator — no separate pre-flight call is required. Page-cache sizing lives on DatabaseCacheSize, not here.

Statistics

Background statistics rebuild configuration (HyperLogLog, MCV, Histogram). Null disables the background statistics worker (statistics can still be rebuilt manually).

public StatisticsOptions Statistics { get; set; }

Property Value

StatisticsOptions

Timeouts

Lock acquisition timeout configuration for all engine subsystems.

public TimeoutOptions Timeouts { get; set; }

Property Value

TimeoutOptions

Transient

Transient storage configuration (heap-backed pages for Transient components).

public TransientOptions Transient { get; set; }

Property Value

TransientOptions

Wal

WAL writer configuration. WAL + checkpoint are mandatory: this always resolves to a non-null configuration. To run without disk I/O (tests, benchmarks, throwaway sessions), register an in-memory Typhon.Engine.Internals.IWalFileIO in DI rather than disabling the WAL.

public WalWriterOptions Wal { get; set; }

Property Value

WalWriterOptions
