类 KustoIngestionProperties

KustoIngestionProperties 类包含基本引入属性，可用于精细控制引入过程。

属性	含义
DatabaseName	要将数据引入到其中的数据库的名称
TableName	要将数据引入到其中的表的名称
DropByTags	每个盘区都会有的标记。 DropByTags 是永久性的，可以按如下方式使用：.show table T extents where tags has 'some tag' 或 .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags	按盘区写入的标记。 以后可以与 IngestIfNotExists 属性一起使用，以免引入相同的数据两次。 有关详细信息，请参阅 ingest-by: tags。
IngestionMapping	保存对现有映射的引用或列映射列表
AdditionalTags	根据需要添加额外标记
IngestIfNotExists	不希望再次引入的标记的列表（按表）
ValidationPolicy	数据验证定义。
格式	要引入的数据的格式
AdditionalProperties	其他作为引入属性传递给引入命令的属性。 这些属性会被传递，因为并非所有引入属性都以此类的独立成员的形式表示

public class KustoIngestionProperties
{
    public string DatabaseName { get; set; }
    public string TableName { get; set; }
    public IEnumerable<string> DropByTags { get; set; }
    public IEnumerable<string> IngestByTags { get; set; }
    public IEnumerable<string> AdditionalTags { get; set; }
    public IEnumerable<string> IngestIfNotExists { get; set; }
    public IngestionMapping IngestionMapping { get; set; }
    public ValidationPolicy ValidationPolicy { get; set; }
    public DataSourceFormat? Format { get; set; }
    public bool IgnoreSizeLimit { get; set; } // Determines whether the limit of 4GB per single ingestion source should be ignored. Defaults to false.
    public IDictionary<string, string> AdditionalProperties { get; set; }

    public KustoIngestionProperties(string databaseName, string tableName);
}

类 SourceOptions

SourceOptions 和派生类封装源数据的其他信息和处理选项。 支持的源之间的具体信息有所不同

    // Base class
    public abstract class SourceOptions
    {
        public Guid SourceId  { get; set; };    // Identifies the ingestion source
        public bool Compress { get; set; };     // Determines whether data should be compressed before being uploaded.
    }

    // Represents a local file/blob/ADLSv2 file
    public sealed class StorageSourceOptions : SourceOptions
    {
        public long? Size { get; set; };    // Uncompressed data size. Should be used to comunicate the file size to the service for efficient ingestion
        public bool DeleteSourceOnSuccess { get; set; };    // Indicates whether the ingestion source should be deleted after successful ingestion. Defaults to 'false'. When set to 'true', will require the service to individually delete each blob, which could put extra pressure on the service.
        public DataSourceCompressionType CompressionType { get; set; }; //  Indicates compression used. Defaults to 'none'
    }

类 IngestionMapping

保存对现有映射的引用或列映射列表。

属性	含义
IngestionMappings	列映射，每个列映射均描述目标列数据及其源
IngestionMappingKind	IngestionMappings 属性中描述的映射的类型 - 以下类型之一：Csv、Json、Avro、Parquet、SStream、Orc、ApacheAvro 或 W3CLogFile
IngestionMappingReference	预先创建的映射名称

public class IngestionMapping
{
    public IEnumerable<ColumnMapping> IngestionMappings { get; set; }
    public IngestionMappingKind IngestionMappingKind { get; set; }
    public string IngestionMappingReference { get; set; }

    public IngestionMapping()
    public IngestionMapping(IngestionMapping ingestionMapping)
}

枚举 DataSourceFormat

public enum DataSourceFormat
{
    csv,        // Data is in a CSV(-comma-separated values) format
    tsv,        // Data is in a TSV(-tab-separated values) format
    scsv,       // Data is in a SCSV(-semicolon-separated values) format
    sohsv,      // Data is in a SOHSV(-SOH (ASCII 1) separated values) format
    psv,        // Data is in a PSV (pipe-separated values) format
    tsve,       // Tab-separated value with '\' escaping character.
    txt,        // Each record is a line and has just one field
    raw,        // The entire stream/file/blob is a single record having a single field
    json,       // Data is in a JSON-line format (each line is record with a single JSON value)
    multijson,  // The data stream is a concatenation of JSON documents (property bags all)
    avro,       // Data is in a AVRO format
    orc,        // Data is in a ORC format
    parquet,    // Data is in a Parquet format
}

KustoIngestionProperties 定义的示例

var guid = new Guid().ToString();
var kustoIngestionProperties = new KustoIngestionProperties("TargetDatabase", "TargetTable")
{
    DropByTags = new List<string> { DateTime.Today.ToString() },
    IngestByTags = new List<string> { guid },
    AdditionalTags = new List<string> { "some tags" },
    IngestIfNotExists = new List<string> { guid },
    IngestionMapping = new IngestionMapping() {
        IngestionMappingKind = Data.Ingestion.IngestionMappingKind.Csv,
        IngestionMappings = new ColumnMapping[] { new ColumnMapping() {
            ColumnName = "stringColumn",
            Properties = new Dictionary<string, string>() {
            { MappingConsts.Ordinal, "1"} }
        } },
    },
    ValidationPolicy = new ValidationPolicy { ValidationImplications = ValidationImplications.Fail, ValidationOptions = ValidationOptions.ValidateCsvInputConstantColumns },
    Format = DataSourceFormat.csv
};

接口 IKustoQueuedIngestClient

IKustoQueuedIngestClient 接口添加了用于跟踪引入操作结果的跟踪方法，并为引入客户端公开 RetryPolicy。

类 KustoQueuedIngestionProperties

KustoQueuedIngestionProperties 类使用几个可用于微调引入行为的控制旋钮扩展了 KustoIngestionProperties。

属性	含义
FlushImmediately	默认为 false。 如果设为 true，将绕过数据管理服务的聚合机制
IngestionReportLevel	控制引入状态报告的级别（默认为 FailuresOnly）。 为了获得良好的性能和存储使用率，建议你不要将 IngestionReportLevel 设为 FailuresAndSuccesses
IngestionReportMethod	控制引入状态报告的目标。 可用选项包括：Azure 队列和/或 Azure 表。 默认为 Queue。
