Overview
A source that records can be read and decoded from.
Instance Attribute Summary collapse
-
#base_specs ⇒ Array<Hash<String,Object>>
While splitting, sources may specify the produced bundles as differences against another source, in order to save backend-side memory and allow bigger jobs.
-
#codec ⇒ Hash<String,Object>
The codec to use to decode data read from the source.
-
#does_not_need_splitting ⇒ Boolean
(also: #does_not_need_splitting?)
Setting this value to true hints to the framework that the source doesn't need splitting, and using SourceSplitRequest on it would yield SOURCE_SPLIT_OUTCOME_USE_CURRENT.
-
#metadata ⇒ Google::Apis::DataflowV1b3::SourceMetadata
Metadata about a Source useful for automatically optimizing and tuning the pipeline, etc.
-
#spec ⇒ Hash<String,Object>
The source to read from, plus its parameters.
Instance Method Summary collapse
-
#initialize(**args) ⇒ Source
constructor
A new instance of Source.
-
#update!(**args) ⇒ Object
Update properties of this object.

#initialize(**args) ⇒ Source

While splitting, sources may specify the produced bundles as differences
against another source, in order to save backend-side memory and allow bigger
jobs. For details, see SourceSplitRequest. To support this use case, the full
set of parameters of the source is logically obtained by taking the latest
explicitly specified value of each parameter in the order: base_specs (later
items win), spec (overrides anything in base_specs).
Corresponds to the JSON property baseSpecs

#codec ⇒ Hash<String,Object>

#does_not_need_splitting ⇒ Boolean Also known as: does_not_need_splitting?
Setting this value to true hints to the framework that the source doesn't need
splitting, and using SourceSplitRequest on it would yield
SOURCE_SPLIT_OUTCOME_USE_CURRENT. E.g. a file splitter may set this to true
when splitting a single file into a set of byte ranges of appropriate size,
and set this to false when splitting a filepattern into individual files.
However, for efficiency, a file splitter may decide to produce file subranges
directly from the filepattern to avoid a splitting round-trip. See
SourceSplitRequest for an overview of the splitting process. This field is
meaningful only in the Source objects populated by the user (e.g. when filling
in a DerivedSource). Source objects supplied by the framework to the user don'
t have this field populated.
