Class KustoIngestionProperties

KustoIngestionProperties class contains basic ingestion properties for fine control over the ingestion process and the way Kusto engine will handle it.

Property Meaning
DatabaseName Name of the database to ingest into
TableName Name of the table to ingest into
DropByTags Tags that each extent will have. DropByTags are permanent and can be used as follows: .show table T extents where tags has 'some tag' or .drop extents <| .show table T extents where tags has 'some tag'
IngestByTags Tags that are written per extent. Can later be used with the IngestIfNotExists property to avoid ingesting the same data twice
IngestionMapping Holds either a reference to an exiting mapping or a list of column mappings
AdditionalTags Additional tags as needed
IngestIfNotExists List of tags that you don't want to ingest again (per table)
ValidationPolicy Data validation definitions.
Format Format of the data being ingested
AdditionalProperties Other properties that will be passed as ingestion properties to the ingestion command. The properties will be passed because not all of the ingestion properties are represented in a separate member of this class
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);
}

Class SourceOptions

SourceOptions and derived classes encapsulate additional information and handling options for the source data. The specifics differ between supported sources

    // 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'
    }

Class IngestionMapping

Holds a reference to an existing mapping or a list of column mappings.

Property Meaning
IngestionMappings Column mappings, each describing the target column data and its source
IngestionMappingKind Kind of mapping described in the IngestionMappings property - one of: Csv, Json, Avro, Parquet, SStream, Orc, ApacheAvro or W3CLogFile
IngestionMappingReference The pre-created mapping name
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
}

Example of KustoIngestionProperties definition

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
};

Interface IKustoQueuedIngestClient

IKustoQueuedIngestClient interface adds tracking methods that follow the ingestion operation result and exposes RetryPolicy for the ingest client.

  • PeekTopIngestionFailures
  • GetAndDiscardTopIngestionFailures
  • GetAndDiscardTopIngestionSuccesses
public interface IKustoQueuedIngestClient : IKustoIngestClient
{
    /// <summary>
    /// Peeks top (== oldest) ingestion failures  
    /// </summary>
    /// <param name="messagesLimit">Maximum ingestion failures to peek. Default value peeks 32 messages.</param>
    /// <returns>A task which its result contains IEnumerable of <see cref="IngestionFailure"/>. The received messages won't be discarded from the relevant azure queue.</returns>
    Task<IEnumerable<IngestionFailure>> PeekTopIngestionFailures(int messagesLimit = -1);

    /// <summary>
    /// Returns and deletes top (== oldest) ingestion failure notifications 
    /// </summary>
    /// <param name="messagesLimit">Maximum ingestion failure notifications to get. Default value peeks 32 messages.</param>

    Task<IEnumerable<IngestionSuccess>> GetAndDiscardTopIngestionSuccesses(int messagesLimit = -1);

    /// <summary>
    /// An implementation of IRetryPolicy that will be enforced on every ingest call,
    /// which affects how the ingest client handles retrying on transient failures 
    /// </summary>
    IRetryPolicy QueueRetryPolicy { get; set; }
}

Class KustoQueuedIngestionProperties

KustoQueuedIngestionProperties class extends KustoIngestionProperties with several control knobs that can be used to fine-tune the ingestion behavior.

FlushImmediately Defaults to false. If set to true, will bypass aggregation mechanism of the Data Management service
