ConfigurationOptions

Namespace: Reaqtor.QueryEngine

Assembly: Reaqtor.QueryEngine.dll

Syntax

public sealed class ConfigurationOptions : Object

Properties

CheckpointDegreeOfParallelism

Gets or sets the degree of parallelism for checkpointing operations.

Declaration

public int CheckpointDegreeOfParallelism { get; set; }

Property Value

Type	Description
System.Int32

DumpRecoveryStateBlobs

Gets or sets the flag enabling persistence of recovery state blobs which can be used to debug recovery issues. See DumpRecoveryStatePath to configure the path to write the blobs to.

Declaration

public bool DumpRecoveryStateBlobs { get; set; }

Property Value

Type	Description
System.Boolean

DumpRecoveryStatePath

Gets or sets the path where recovery state dumps are written to. This setting only takes effect if DumpRecoveryStateBlobs is set to true.

Declaration

public string DumpRecoveryStatePath { get; set; }

Property Value

Type	Description
System.String

ExpressionPolicy

Gets the expression options for the query engine, including options related to caching of compiled delegates for evaluation and caching of expressions for compact storage in memory.

Declaration

public ExpressionPolicy ExpressionPolicy { get; }

Property Value

Type	Description
ExpressionPolicy

ForeignFunctionBinder

Gets the foreign function binder used to resolve foreign functions during expression binding.

Declaration

public Func<string, Expression> ForeignFunctionBinder { get; set; }

Property Value

Type	Description
System.Func<System.String, System.Linq.Expressions.Expression>

GarbageCollectionEnabled

Gets or sets the flag enabling garbage collection of orphaned artifacts. This flag does not enable sweeping by default. See GarbageCollectionSweepEnabled to configure sweeping of orphaned artifacts.

Declaration

public bool GarbageCollectionEnabled { get; set; }

Property Value

Type	Description
System.Boolean

GarbageCollectionSweepBudgetPerCheckpoint

Gets or sets the maximum number of sweep (delete) operations the garbage collector is allowed to commit per checkpoint. For this flag to take effect, garbage collection and sweeping have to be enabled. See GarbageCollectionEnabled to turn on the garbage collector. See GarbageCollectionSweepEnabled to turn on sweeping.

Declaration

public int GarbageCollectionSweepBudgetPerCheckpoint { get; set; }

Property Value

Type	Description
System.Int32

GarbageCollectionSweepEnabled

Gets or sets the flag enabling garbage collection of orphaned artifacts by undefining these during the sweep phase. For this flag to take effect, garbage collection has to be enabled. See GarbageCollectionEnabled to turn on the garbage collector.

Declaration

public bool GarbageCollectionSweepEnabled { get; set; }

Property Value

Type	Description
System.Boolean

RecoveryDegreeOfParallelism

Gets or sets the degree of parallelism for recovery operations.

Declaration

public int RecoveryDegreeOfParallelism { get; set; }

Property Value

Type	Description
System.Int32

TemplatizeExpressions

Gets or sets the flag enabling templatization of expressions. By templatizing expressions, checkpoint and recovery state can be significantly reduced if many expressions have the same shape.

Declaration

public bool TemplatizeExpressions { get; set; }

Property Value

Type	Description
System.Boolean

TemplatizeRecoveredEntitiesQuota

Gets or sets the maximum number of entities that will be migrated to templatized form in a single checkpoint. If not set, the default value is 0.

Declaration

public int TemplatizeRecoveredEntitiesQuota { get; set; }

Property Value

Type	Description
System.Int32

TemplatizeRecoveredEntitiesRegex

Gets or sets the regular expression applied to the entity key to determine if the entity should be migrated to templatized form. If not set, all entities can be migrated.

Declaration

public string TemplatizeRecoveredEntitiesRegex { get; set; }

Property Value

Type	Description
System.String
