KustoIngestionProperties osztály

A KustoIngestionProperties osztály alapvető betöltési tulajdonságokat tartalmaz a betöltési folyamat részletes szabályozásához.

Tulajdonság Értelmezés
DatabaseName Annak az adatbázisnak a neve, amelybe betöltendő
TableName Annak a táblának a neve, amelybe betöltendő
DropByTags Az egyes mértékek címkéi. A DropByTagek állandóak, és a következőképpen használhatók: .show table T extents where tags has 'some tag' vagy .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags A terjedelemenként írt címkék. Később a IngestIfNotExists tulajdonsággal együtt is használható, hogy elkerülje ugyanazokat az adatokat kétszer. További információ: betöltési címkék.
IngestionMapping Egy kilépési leképezésre vagy egy oszlopleképezések listájára mutató hivatkozást tárol
További címkék Szükség szerint további címkék
IngestIfNotExists Azon címkék listája, amelyeket nem szeretne újra betöltésre használni (táblázatonként)
ValidationPolicy Adatérvényesítési definíciók.
Formátum A betöltés alatt álló adatok formátuma
Továbbitulajdonságok Egyéb tulajdonságok, amelyek betöltési tulajdonságokként vannak átadva a betöltési parancsnak. A tulajdonságok átadása azért van, mert nem minden betöltési tulajdonság jelenik meg ennek az osztálynak egy külön tagjában

    public string TableName { get; set; }

    public KustoIngestionProperties(string databaseName, string tableName);
}

Osztály SourceOptions

A SourceOptions és a származtatott osztályok további információkat és kezelési lehetőségeket tartalmaznak a forrásadatokhoz. A konkrétumok különböznek a támogatott forrásoktól

    // 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'
    }

OsztálybetöltésMapping

Meglévő leképezésre vagy oszlopleképezések listájára mutató hivatkozást tartalmaz.

Tulajdonság Értelmezés
IngestionMappings Oszlopleképezések, amelyek a céloszlop adatait és forrását írják le
IngestionMappingKind Az IngestionMappings tulajdonságban leírt leképezés típusa – az egyik: Csv, Json, Avro, Parquet, SStream, Orc, ApacheAvro vagy W3CLogFile
IngestionMappingReference Az előre létrehozott leképezés neve 
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

    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

KustoQueuedIngestionProperties osztály

A KustoQueuedIngestionProperties osztály több vezérlőgombbal bővíti ki a KustoIngestionProperties osztályt, amelyekkel finomhangolható a betöltési viselkedés.

Tulajdonság Értelmezés
FlushImmediately Alapértelmezés szerint a értékre van kapcsolva false. Ha a értékre truevan állítva, megkerüli a adatkezelés szolgáltatás összesítési mechanizmusát
IngestionReportLevel A betöltési állapot jelentésének szintjét szabályozza (alapértelmezés szerint a értékre FailuresOnly). A jó teljesítmény és a tárterület-használat érdekében javasoljuk, hogy ne állítsa be az IngestionReportLevel értéket a következő értékre: FailuresAndSuccesses
IngestionReportMethod A betöltési állapotjelentés célját szabályozza. Az elérhető lehetőségek a következők: Azure Queue, Azure Table vagy mindkettő. Az alapértelmezett érték: Queue.
