#clustering_fields=(fields) ⇒ Object

Sets one or more fields on which the destination table should be clustered. Must be specified with time-based partitioning, data in the table will be first partitioned and subsequently clustered.

Only top-level, non-repeated, simple-type fields are supported. When you cluster a table using multiple columns, the order of columns you specify is important. The order of the specified columns determines the sort order of the data.

See Google::Cloud::Bigquery::LoadJob#clustering_fields.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

gs_url = "gs://my-bucket/file-name.csv"
load_job = dataset.load_job "my_new_table", gs_url do |job|
  job.time_partitioning_type  = "DAY"
  job.time_partitioning_field = "dob"
  job.schema do |schema|
    schema.timestamp "dob", mode: :required
    schema.string "first_name", mode: :required
    schema.string "last_name", mode: :required
  end
  job.clustering_fields = ["last_name", "first_name"]
end

load_job.wait_until_done!
load_job.done? #=> true

Parameters:

  • fields (Array<String>)

    The clustering fields. Only top-level, non-repeated, simple-type fields are supported.

end

#max_bad_records=(val) ⇒ Object

Sets the maximum number of bad records that can be ignored.

Parameters:

  • val (Integer)

    The maximum number of bad records that BigQuery can ignore when running the job. If the number of bad records exceeds this value, an invalid error is returned in the job result. The default value is 0, which requires that all records are valid.

end

#null_marker=(val) ⇒ Object

Sets the string that represents a null value in a CSV file.

Parameters:

  • val (String)

    Specifies a string that represents a null value in a CSV file. For example, if you specify \N, BigQuery interprets \N as a null value when loading a CSV file. The default value is the empty string. If you set this property to a custom value, BigQuery throws an error if an empty string is present for all data types except for STRING and BYTE. For STRING and BYTE columns, BigQuery interprets the empty string as an empty value.

#projection_fields=(new_fields) ⇒ Object

Sets the projection fields.

If the format option is set to datastore_backup, indicates which entity properties to load from a Cloud Datastore backup. Property names are case sensitive and must be top-level properties.

end

#quote=(val) ⇒ Object

Sets the character to use to quote string values in CSVs.

Parameters:

  • val (String)

If your data does not contain quoted sections, set the property value to an empty string. If your data contains quoted newline characters, you must also set the allowQuotedNewlines property to true.

#range_partitioning_start=(range_start) ⇒ Object

Sets the start of range partitioning, inclusive, for the destination table. See Creating and using integer range partitioned tables.

You can only set range partitioning when creating a table. BigQuery does not allow you to change partitioning on an existing table.

See #range_partitioning_field=, #range_partitioning_interval= and #range_partitioning_end=.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

gs_url = "gs://my-bucket/file-name.csv"
load_job = dataset.load_job "my_new_table", gs_url do |job|
  job.schema do |schema|
    schema.integer "my_table_id", mode: :required
    schema.string "my_table_data", mode: :required
  end
  job.range_partitioning_field = "my_table_id"
  job.range_partitioning_start = 0
  job.range_partitioning_interval = 10
  job.range_partitioning_end = 100
end

load_job.wait_until_done!
load_job.done? #=> true

Parameters:

  • range_start (Integer)

    The start of range partitioning, inclusive.

#record(name, description: nil, mode: nil) {|nested_schema| ... } ⇒ Object

Adds a record field to the schema. A block must be passed describing the nested fields of the record. For more information about nested and repeated records, see Loading denormalized, nested, and repeated data .

See Schema#record.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"

  schema.record "cities_lived", mode: :repeated do |cities_lived|
    cities_lived.string "place", mode: :required
    cities_lived.integer "number_of_years", mode: :required
  end
end

Parameters:

  • name (String)

    The field name. The name must contain only letters (a-z, A-Z), numbers (0-9), or underscores (_), and must start with a letter or underscore. The maximum length is 128 characters.

  • description (String) (defaults to: nil)

    A description of the field.

  • mode (Symbol) (defaults to: nil)

    The field's mode. The possible values are :nullable, :required, and :repeated. The default value is :nullable.

Yields:

  • (nested_schema)

    a block for setting the nested schema

Yield Parameters:

  • nested_schema (Schema)

    the object accepting the nested schema

#schema(replace: false) {|schema| ... } ⇒ Google::Cloud::Bigquery::Schema

Returns the table's schema. This method can also be used to set, replace, or add to the schema by passing a block. See Schema for available methods.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |j|
  j.schema do |s|
    s.string "first_name", mode: :required
    s.record "cities_lived", mode: :repeated do |r|
      r.string "place", mode: :required
      r.integer "number_of_years", mode: :required
    end
  end
end

Parameters:

  • replace (Boolean) (defaults to: false)

    Whether to replace the existing schema with the new schema. If true, the fields will replace the existing schema. If false, the fields will be added to the existing schema. When a table already contains data, schema changes must be additive. Thus, the default value is false.

Yields:

  • (schema)

    a block for setting the schema

Yield Parameters:

  • schema (Schema)

    the object accepting the schema

#schema=(new_schema) ⇒ Object

Sets the schema of the destination table.

Examples:

require "google/cloud/bigquery"

bigquery = Google::Cloud::Bigquery.new
schema = bigquery.schema do |s|
  s.string "first_name", mode: :required
  s.record "cities_lived", mode: :repeated do |nested_schema|

  end
end
dataset = bigquery.dataset "my_dataset"
job = dataset.load_job "my_table", "gs://abc/file" do |j|
  j.schema = schema
end

Parameters:

  • new_schema (Google::Cloud::Bigquery::Schema)

    The schema for the destination table. Optional. The schema can be omitted if the destination table already exists, or if you're loading data from a source that includes a schema, such as Avro or a Google Cloud Datastore backup.

end

#schema_update_options=(new_options) ⇒ Object

Sets the schema update options, which allow the schema of the destination table to be updated as a side effect of the load job if a schema is autodetected or supplied in the job configuration. Schema update options are supported in two cases: when write disposition is WRITE_APPEND; when write disposition is WRITE_TRUNCATE and the destination table is a partition of a table, specified by partition decorators. For normal tables, WRITE_TRUNCATE will always overwrite the schema. One or more of the following values are specified:

  • ALLOW_FIELD_ADDITION: allow adding a nullable field to the schema.
  • ALLOW_FIELD_RELAXATION: allow relaxing a required field in the original schema to nullable.

Parameters:

  • new_options (Array<String>)

    The new schema update options.
