Klasa KustoIngestionProperties

Klasa KustoIngestionProperties zawiera podstawowe właściwości pozyskiwania w celu uzyskania dokładnej kontroli nad procesem pozyskiwania.

Właściwość Znaczenie
DatabaseName Nazwa bazy danych do pozyskiwania
TableName Nazwa tabeli do pozyskiwania
DropByTags Tagi, które będą miały każdy zakres. DropByTags są trwałe i mogą być używane w następujący sposób: .show table T extents where tags has 'some tag' lub .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags Tagi zapisywane w każdym zakresie. Można później używać z właściwością , IngestIfNotExists aby uniknąć dwukrotnego pozyskiwania tych samych danych. Aby uzyskać więcej informacji, zobacz ingest-by: tags (Pozyskiwanie według tagów).
IngestionMapping Przechowuje odwołanie do mapowania zakończenia lub listy mapowań kolumn
Dodatkowe tagi Dodatkowe tagi zgodnie z potrzebami
IngestIfNotExists Lista tagów, których nie chcesz ponownie pozyskiwać (na tabelę)
ValidationPolicy Definicje weryfikacji danych.
Format Format pozyskiwanych danych
Dodatkowe właściwości Inne właściwości, które są przekazywane jako właściwości pozyskiwania do polecenia pozyskiwania. Właściwości są przekazywane, ponieważ nie wszystkie właściwości pozyskiwania są reprezentowane w osobnym elemencie członkowskim tej klasy 
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);
}

SourceOptions klasy

Klasy sourceOptions i pochodne hermetyzują dodatkowe informacje i opcje obsługi danych źródłowych. Specyfika różni się między obsługiwanymi źródłami

    // 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'
    }

IngestionMapping klasy

Zawiera odwołanie do istniejącego mapowania lub listy mapowań kolumn.

Właściwość Znaczenie
IngestionMappings Mapowania kolumn, z których każda opisuje dane kolumny docelowej i jej źródło
IngestionMappingKind Rodzaj mapowania opisanego we właściwości IngestionMappings — jeden z następujących elementów: Csv, Json, Avro, Parquet, SStream, Orc, ApacheAvro lub W3CLogFile
IngestionMappingReference Wstępnie utworzona nazwa mapowania 
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)
}

Wyliczenie 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
}

Klasa KustoQueuedIngestionProperties

Klasa KustoQueuedIngestionProperties rozszerza właściwość KustoIngestionProperties za pomocą kilku pokrętł sterujących, których można użyć do dostosowania zachowania pozyskiwania.

Właściwość Znaczenie
FlushImmediately Wartość domyślna to false. Jeśli jest ustawiona wartość true, spowoduje obejście mechanizmu agregacji usługi Zarządzanie danymi
IngestionReportLevel Określa poziom raportowania stanu pozyskiwania (wartość domyślna to FailuresOnly). Aby uzyskać dobrą wydajność i użycie magazynu, zalecamy, aby nie ustawić parametru IngestionReportLevel na FailuresAndSuccesses
IngestionReportMethod Steruje celem raportowania stanu pozyskiwania. Dostępne opcje to: Azure Queue, Azure Table lub oba te opcje. Wartość domyślna to Queue.
