クラス KustoIngestionProperties

KustoIngestionProperties クラスには、インジェストプロセスを細かく制御するための基本的なインジェストプロパティが含まれています。

プロパティ	説明
DatabaseName	取り込むデータベースの名前
TableName	取り込むテーブルの名前
DropByTags	各エクステントに含まれるタグ。 DropByTags は永続的であり、`.show table T extents where tags has 'some tag'` または `.drop extents <\| .show table T extents where tags has 'some tag'`のように使用できます
IngestByTags	エクステントごとに記述されるタグ。後でプロパティと共に `IngestIfNotExists` 使用して、同じデータを 2 回取り込むのを避けることができます。詳細については、ingest-by: タグに関する記事を参照してください。
IngestionMapping	終了したマッピングへの参照または列マッピングの一覧を保持します
AdditionalTags	必要に応じて追加のタグ
IngestIfNotExists	再度取り込みたくないタグの一覧 (テーブルごと)
ValidationPolicy	データ検証の定義。
フォーマット	取り込まれているデータの形式
AdditionalProperties	インジェストプロパティとしてインジェストコマンドに渡されるその他のプロパティ。すべてのインジェストプロパティがこのクラスの別のメンバーで表されるわけではないため、プロパティが渡されます

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);
}

クラス SourceOptions

SourceOptions および派生クラスは、ソースデータの追加情報と処理オプションをカプセル化します。サポートされているソースによって仕様が異なります

    // 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'
    }

クラス IngestionMapping

既存のマッピングへの参照または列マッピングの一覧を保持します。

プロパティ	説明
IngestionMappings	各列にターゲット列のデータとそのソースが説明されている列マッピング
IngestionMappingKind	IngestionMappings プロパティに説明されているマッピングの種類: Csv、Json、Avro、Parquet、SStream、Orc、ApacheAvro、または W3CLogFileのうちの 1 つ
IngestionMappingReference	事前に作成されたマッピング名

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)
}

列挙型 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
}

    DropByTags = new List<string> { DateTime.Today.ToString() },

インターフェイス IKustoQueuedIngestClient

IKustoQueuedIngestClient インターフェイスは、インジェスト操作の結果に従い、インジェストクライアントの RetryPolicy を公開する追跡メソッドを追加します。

クラス KustoQueuedIngestionProperties

KustoQueuedIngestionProperties クラスは、インジェスト動作を微調整するために使用できるいくつかのコントロールのノブを持つ KustoIngestionProperties を拡張します。

プロパティ	説明
FlushImmediately	既定値は `false` です。 `true` に設定すると、データ管理サービスの集計メカニズムがバイパスされます
IngestionReportLevel	インジェストステータスレポートのレベルを制御します (既定値: `FailuresOnly` )。最適なパフォーマンスとストレージの使用のため、IngestionReportLevel を `FailuresAndSuccesses`に設定しないことをお勧めします
IngestionReportMethod	インジェストステータスレポートのターゲットを制御します。使用可能なオプションは、Azure キュー、Azure テーブル、またはその両方です。既定値は `Queue` です。

public class KustoQueuedIngestionProperties : KustoIngestionProperties
{
    /// <summary>
    /// Allows to stop the batching phase and will cause to an immediate ingestion.
    /// Defaults to 'false'. 
    /// </summary>
    public bool FlushImmediately { get; set; }

    /// <summary>
    /// Controls the ingestion status report level.
    /// Defaults to 'FailuresOnly'.
    /// </summary>
    public IngestionReportLevel ReportLevel { get; set; }

    /// <summary>
    /// Controls the target of the ingestion status reporting. Available options are Azure Queue, Azure Table, or both.
    /// Defaults to 'Queue'.
    /// </summary>
    public IngestionReportMethod ReportMethod { get; set; }
    
    /// <summary>
    /// Controls the target of the ingestion status reporting. Available options are Azure Queue, Azure Table, or both.
    /// Defaults to 'Queue'.
    /// </summary>
    public IngestionReportMethod ReportMethod;

    public KustoQueuedIngestionProperties(string databaseName, string tableName);
