BatchingSqlJournalSetup(Config, QueryConfiguration)

Initializes a new instance of the BatchingSqlJournalSetup class.

Declaration

protected BatchingSqlJournalSetup(Config config, QueryConfiguration namingConventions)

Parameters

Type	Name	Description
Config	config	The configuration used to configure the journal.
QueryConfiguration	namingConventions	The naming conventions used by the database to construct valid SQL statements.

Exceptions

Type	Condition
ConfigurationException	This exception is thrown for a couple of reasons. A connection string for the SQL event journal was not specified. An unknown `isolation-level` value was specified. Acceptable `isolation-level` values include: chaos \| read-committed \| read-uncommitted \| repeatable-read \| serializable \| snapshot \| unspecified
ArgumentNullException	This exception is thrown when the specified `config` is undefined.

BatchingSqlJournalSetup(String, Int32, Int32, Int32, Boolean, TimeSpan, IsolationLevel, CircuitBreakerSettings, ReplayFilterSettings, QueryConfiguration, String)

Initializes a new instance of the BatchingSqlJournalSetup class.

Declaration

[Obsolete("Use constructor with separate read and write isolation level instead. (since v1.5.2)")]
protected BatchingSqlJournalSetup(string connectionString, int maxConcurrentOperations, int maxBatchSize, int maxBufferSize, bool autoInitialize, TimeSpan connectionTimeout, IsolationLevel isolationLevel, CircuitBreakerSettings circuitBreakerSettings, ReplayFilterSettings replayFilterSettings, QueryConfiguration namingConventions, string defaultSerializer)

Parameters

Type	Name	Description
String	connectionString	The connection string used to connect to the database.
Int32	maxConcurrentOperations	The maximum number of batch operations allowed to be executed at the same time.
Int32	maxBatchSize	The maximum size of single batch of operations to be executed over a single DbConnection.
Int32	maxBufferSize	The maximum size of requests stored in journal buffer.
Boolean	autoInitialize	If set to `true`, the journal executes all SQL scripts stored under the Initializers collection prior to starting executing any requests.
TimeSpan	connectionTimeout	The maximum time given for executed DbCommand to complete.
IsolationLevel	isolationLevel	The isolation level of transactions used during query execution.
CircuitBreakerSettings	circuitBreakerSettings	The settings used by the CircuitBreaker when for executing request batches.
ReplayFilterSettings	replayFilterSettings	The settings used when replaying events from database back to the persistent actors.
QueryConfiguration	namingConventions	The naming conventions used by the database to construct valid SQL statements.
String	defaultSerializer	The serializer used when no specific type matching can be found.

Properties

AutoInitialize

If true, once created, journal will run all SQL scripts stored under Initializers collection prior to starting executing any requests. In most implementation this is used to initialize necessary tables.

Declaration

public bool AutoInitialize { get; }

Property Value

Type	Description
Boolean

CircuitBreakerSettings

Settings specific to CircuitBreaker, which is used internally for executing request batches.

Declaration

public CircuitBreakerSettings CircuitBreakerSettings { get; }

Property Value

Type	Description
CircuitBreakerSettings

ConnectionString

Connection string to a SQL database.

Declaration

public string ConnectionString { get; }

Property Value

Type	Description
String

ConnectionTimeout

Maximum time given for executed DbCommand to complete.

Declaration

public TimeSpan ConnectionTimeout { get; }

Property Value

Type	Description
TimeSpan

DefaultSerializer

The default serializer used when not type override matching is found

Declaration

[Obsolete("This property should never be used for writes, use the default `System.Object` serializer instead")]
public string DefaultSerializer { get; }

Property Value

Type	Description
String

IsolationLevel

Isolation level of transactions used during write query execution.

Declaration

[Obsolete("Use WriteIsolationLevel property instead")]
public IsolationLevel IsolationLevel { get; }

Property Value

Type	Description
IsolationLevel

MaxBatchSize

Maximum size of single batch of operations to be executed over a single DbConnection.

Declaration

public int MaxBatchSize { get; }

Property Value

Type	Description
Int32

| Improve this Doc View Source

MaxBufferSize

Maximum size of requests stored in journal buffer. Once buffer will be surpassed, it will start to apply OnBufferOverflow(IJournalMessage) method to incoming requests.

Declaration

public int MaxBufferSize { get; }

Property Value

Type	Description
Int32

| Improve this Doc View Source

MaxConcurrentOperations

Maximum number of batch operations allowed to be executed at the same time. Each batch operation must acquire a DbConnection, so this setting can be effectively used to limit the usage of ADO.NET connection pool by current journal.

Declaration

public int MaxConcurrentOperations { get; }

Property Value

Type	Description
Int32

NamingConventions

Database specific naming conventions (table and column names) used to construct valid SQL statements.

Declaration

public QueryConfiguration NamingConventions { get; }

Property Value

Type	Description
QueryConfiguration
