    Parallel Bulk Loader

    Table of Contents

    The Parallel Bulk Loader (PBL) job enables bulk ingestion of structured and semi-structured data from big data systems, NoSQL databases, and common file formats like Parquet and Avro.

    Configuration properties

    Use this job when you want to load data into Fusion from a SparkSQL compliant datasource, and send this data to any Spark supported datasource (Solr/Index Pipeline/S3/GCS/...).

    id - stringrequired

    The ID for this Spark job. Used in the API to reference this job. Allowed characters: a-z, A-Z, dash (-) and underscore (_). Maximum length: 63 characters.

    <= 63 characters

    Match pattern: [a-zA-Z][_\-a-zA-Z0-9]*[a-zA-Z0-9]?

    sparkConfig - array[object]

    Spark configuration settings.

    object attributes:{key required : {
     display name: Parameter Name
     type: string
    }    value : {
     display name: Parameter Value
     type: string
    }    }

    format - stringrequired

    Specifies the input data source format; common examples include: parquet, json, textinputformat

    path - string

    Path to load; for data sources that support multiple paths, separate by commas

    streaming - Streaming

    enableStreaming - boolean

    Stream data from input source to output Solr collection

    outputMode - string

    Specifies the output mode for streaming. E.g., append (default), complete, update

    Default: append

    Allowed values: appendcompleteupdate

    readOptions - array[object]

    Options passed to the data source to configure the read operation; options differ for every data source so refer to the documentation for more information.

    object attributes:{key required : {
     display name: Parameter Name
     type: string
    }    value : {
     display name: Parameter Value
     type: string
    }    }

    outputCollection - string

    Solr Collection to send the documents loaded from the input data source.

    outputIndexPipeline - string

    Send the documents loaded from the input data source to an index pipeline instead of going directly to Solr.

    outputParser - string

    Parser to send the documents to while sending to index pipeline. (Defaults to same as index pipeline)

    defineFieldsUsingInputSchema - boolean

    If true, define fields in Solr using the input schema; if a SQL transform is defined, the fields to define are based on the transformed DataFrame schema instead of the input.

    Default: true

    atomicUpdates - boolean

    Send documents to Solr as atomic updates; only applies if sending directly to Solr and not an index pipeline.

    Default: false

    timestampFieldName - string

    Name of the field that holds a timestamp for each document; only required if using timestamps to filter new rows from the input source.

    clearDatasource - boolean

    If true, delete any documents indexed in Solr by previous runs of this job. Default is false.

    Default: false

    outputPartitions - integer

    Partition the input DataFrame into partitions before writing out to Solr or Fusion

    optimizeOutput - integer

    Optimize the Solr collection down to the specified number of segments after writing to Solr.

    writeOptions - array[object]

    Options used when writing output. For output formats other than solr or index-pipeline, format and path options can be specified here

    object attributes:{key required : {
     display name: Parameter Name
     type: string
    }    value : {
     display name: Parameter Value
     type: string
    }    }

    transformScala - string

    Optional Scala script used to transform the results returned by the data source before indexing. You must define your transform script in a method with signature: def transform(inputDF: Dataset[Row]) : Dataset[Row]

    mlModelId - string

    The ID of the Spark ML PipelineModel stored in the Fusion blob store.

    transformSql - string

    Optional SQL used to transform the results returned by the data source before indexing. The input DataFrame returned from the data source will be registered as a temp table named '_input'. The Scala transform is applied before the SQL transform if both are provided, which allows you to define custom UDFs in the Scala script for use in your transformation SQL.

    shellOptions - array[object]

    Additional options to pass to the Spark shell when running this job.

    object attributes:{key required : {
     display name: Parameter Name
     type: string
    }    value : {
     display name: Parameter Value
     type: string
    }    }

    templateParams - array[object]

    Bind the key/values to the script interpreter

    object attributes:{key required : {
     display name: Parameter Name
     type: string
    }    value : {
     display name: Parameter Value
     type: string
    }    }

    continueAfterFailure - boolean

    If set to true, when a failure occurs when sending a document through an index pipeline, the job will continue onto the next document instead of failing

    Default: false

    type - stringrequired

    Default: parallel-bulk-loader

    Allowed values: parallel-bulk-loader
