클래스 KustoIngestionProperties

KustoIngestionProperties 클래스에는 수집 프로세스를 세부 제어하기 위한 기본 수집 속성이 포함되어 있습니다.

속성 의미
DatabaseName 수집할 데이터베이스의 이름
TableName 수집할 테이블의 이름
DropByTags 각 익스텐트에서 가질 태그입니다. DropByTags는 영구적이며 다음과 같이 사용할 수 있습니다. .show table T extents where tags has 'some tag' 또는 .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags 익스텐트별로 작성된 태그입니다. 나중에 동일한 데이터를 두 번 수집하지 않도록 속성과 함께 IngestIfNotExists 사용할 수 있습니다. 자세한 내용은 ingest-by: 태그를 참조하세요.
IngestionMapping 종료 매핑 또는 열 매핑 목록에 대한 참조를 보유합니다.
AdditionalTags 필요에 따라 추가 태그
IngestIfNotExists 다시 수집하지 않으려는 태그 목록(테이블당)
ValidationPolicy 데이터 유효성 검사 정의.
서식 수집되는 데이터의 형식
AdditionalProperties 수집 속성으로 수집 명령으로 전달되는 기타 속성 입니다. 모든 수집 속성이 이 클래스의 별도 멤버에 표시되지 않으므로 속성이 전달됩니다. 
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);
}

클래스 SourceOptions

SourceOptions 및 파생 클래스는 원본 데이터에 대한 추가 정보 및 처리 옵션을 캡슐화합니다. 지원되는 원본 간에 세부 사항이 다릅니다.

    // 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'
    }

클래스 IngestionMapping

기존 매핑 또는 열 매핑 목록에 대한 참조를 보유합니다.

속성 의미
IngestionMappings 대상 열 데이터 및 해당 원본을 설명하는 각 열 매핑
IngestionMappingKind IngestionMappings 속성에 설명된 매핑 종류 - Csv, Json, Avro, Parquet, SStream, Orc, ApacheAvro 또는 W3CLogFile 중 하나
IngestionMappingReference 미리 생성된 매핑 이름 
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)
}

Enum 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
}

클래스 KustoQueuedIngestionProperties

KustoQueuedIngestionProperties 클래스는 수집 동작을 미세 조정하는 데 사용할 수 있는 여러 컨트롤 노브를 사용하여 KustoIngestionProperties를 확장합니다.

속성 의미
FlushImmediately 기본값은 false입니다. 로 true설정하면 데이터 관리 서비스의 집계 메커니즘을 무시합니다.
IngestionReportLevel 수집 상태 보고 수준을 제어합니다(기본값은 FailuresOnly). 성능 및 스토리지 사용량을 위해 IngestionReportLevel을 로 설정하지 않는 것이 좋습니다. FailuresAndSuccesses
IngestionReportMethod 수집 상태 보고의 대상을 제어합니다. 사용 가능한 옵션은 Azure Queue, Azure Table 또는 둘 다입니다. 기본값은 Queue입니다.
