Amundsen Databuilder

Amundsen Databuilder is a data ingestion library, which is inspired by Apache Gobblin. It could be used in an orchestration framework(e.g. Apache Airflow) to build data from Amundsen. You could use the library either with an adhoc python script(example) or inside an Apache Airflow DAG(example).

For information about Amundsen and our other services, visit the main repository README.md . Please also see our instructions for a quick start setup of Amundsen with dummy data, and an overview of the architecture.

Requirements

Python >= 3.6.x

Concept

ETL job consists of extraction of records from the source, transform records, if necessary, and load records into the sink. Amundsen Databuilder is a ETL framework for Amundsen and there are corresponding components for ETL called Extractor, Transformer, and Loader that deals with record level operation. A component called task controls all these three components. Job is the highest level component in Databuilder that controls task and publisher and is the one that client use to launch the ETL job.

In Databuilder, each components are highly modularized and each components are using namespace based config, HOCON config, which makes it highly reusable and pluggable. (e.g: transformer can be reused within extractor, or extractor can be reused within extractor) (Note that concept on components are highly motivated by Apache Gobblin)

Extractor

Extractor extracts record from the source. This does not neccessarily mean that it only supports pull pattern in ETL. For example, extracting record from messaging bus make it a push pattern in ETL.

Transformer

Transfomer takes record from either extractor or from transformer itself (via ChainedTransformer) to transform record.

Loader

A loader takes record from transformer or from extractor directly and load it to sink, or staging area. As loader is operated in record level, it's not capable of supporting atomicity.

Task

A task orchestrates extractor, transformer, and loader to perform record level operation.

Record

A record is represented by one of models.

Publisher

A publisher is an optional component. It's common usage is to support atomicity in job level and/or to easily support bulk load into the sink.

Job

Job is the highest level component in Databuilder, and it orchestrates task, and publisher.

Model

Models are abstractions representing the domain.

List of extractors

DBAPIExtractor

An extractor that uses Python Database API interface. DBAPI requires three information, connection object that conforms DBAPI spec, a SELECT SQL statement, and a model class that correspond to the output of each row of SQL statement.

job_config = ConfigFactory.from_dict({
        'extractor.dbapi{}'.format(DBAPIExtractor.CONNECTION_CONFIG_KEY): db_api_conn,
        'extractor.dbapi.{}'.format(DBAPIExtractor.SQL_CONFIG_KEY ): select_sql_stmt,
        'extractor.dbapi.model_class': 'package.module_name.class_name'
        })

job = DefaultJob(
    conf=job_config,
    task=DefaultTask(
        extractor=DBAPIExtractor(),
        loader=AnyLoader()))
job.launch()

GenericExtractor

An extractor that takes list of dict from user through config.

HiveTableLastUpdatedExtractor

An extractor that extracts last updated time from Hive metastore and underlying file system. Although, hive metastore has a parameter called "last_modified_time", but it cannot be used as it provides DDL timestamp not DML timestamp. For this reason, HiveTableLastUpdatedExtractor is utilizing underlying file of Hive to fetch latest updated date. However, it is not efficient to poke all files in Hive, and it only pokes underlying storage for non-partitioned table. For partitioned table, it will fetch partition created timestamp, and it's close enough for last updated timestamp.

As getting metadata from files could be time consuming there're several features to increase performance.

Support of multithreading to parallelize metadata fetching. Although, cpython's multithreading is not true multithreading as it's bounded by single core, getting metadata of file is mostly IO bound operation. Note that number of threads should be less or equal to number of connections.
User can pass where clause to only include certain schema and also remove certain tables. For example, by adding something like TBL_NAME NOT REGEXP '(tmp|temp) would eliminate unncecessary computation.

job_config = ConfigFactory.from_dict({
    'extractor.hive_table_last_updated.partitioned_table_where_clause_suffix': partitioned_table_where_clause,
    'extractor.hive_table_last_updated.non_partitioned_table_where_clause_suffix'): non_partitioned_table_where_clause,

    task=DefaultTask(
        extractor=HiveTableLastUpdatedExtractor(),
        loader=AnyLoader()))
job.launch()

HiveTableMetadataExtractor

job_config = ConfigFactory.from_dict({
    'extractor.hive_table_metadata.{}'.format(HiveTableMetadataExtractor.WHERE_CLAUSE_SUFFIX_KEY): where_clause_suffix,
    'extractor.hive_table_metadata.extractor.sqlalchemy.{}'.format(SQLAlchemyExtractor.CONN_STRING): connection_string()})

        loader=AnyLoader()))
job.launch()

    'extractor.cassandra.{}'.format(CassandraExtractor.KWARGS_KEY): {},
    'extractor.cassandra.{}'.format(CassandraExtractor.FILTER_FUNCTION_KEY): my_filter_function,

})
job = DefaultJob(
    conf=job_config,
    task=DefaultTask(
        extractor=CassandraExtractor(),
        loader=AnyLoader()))
job.launch()

If using the function filter options here is the function description

def filter(keytab, table):
  # return False if you don't want to add that table and True if you want to add
  return True

If needed to define more args on the cassandra cluster you can pass through kwargs args

config = ConfigFactory.from_dict({
    'extractor.cassandra.{}'.format(CassandraExtractor.IPS_KEY): [127.0.0.1],
    'extractor.cassandra.{}'.format(CassandraExtractor.KWARGS_KEY): {'port': 9042}
})
# it will call the cluster constructor like this
Cluster([127.0.0.1], **kwargs)

GlueExtractor

    'extractor.glue.{}'.format(GlueExtractor.CLUSTER_KEY): cluster_identifier_string,
    'extractor.glue.{}'.format(GlueExtractor.FILTER_KEY): []})
job = DefaultJob(
    conf=job_config,
    task=DefaultTask(
        extractor=GlueExtractor(),
        loader=AnyLoader()))

[
  {
    "Key": "string",
    "Value": "string",
    "Comparator": "EQUALS"|"GREATER_THAN"|"LESS_THAN"|"GREATER_THAN_EQUALS"|"LESS_THAN_EQUALS"
  }
  ...
]

Delta-Lake-MetadataExtractor

An extractor that runs on a spark cluster and obtains delta-lake metadata using spark sql commands. This custom solution is currently necessary because the hive metastore does not contain all metadata information for delta-lake tables. For simplicity, this extractor can also be used for all hive tables as well.

Because it must run on a spark cluster, it is required that you have an operator (for example a databricks submit run operator) that calls the configuration code on a spark cluster.

spark = SparkSession.builder.appName("Amundsen Delta Lake Metadata Extraction").getOrCreate()
job_config = create_delta_lake_job_config()
dExtractor = DeltaLakeMetadataExtractor()
dExtractor.set_spark(spark)
job = DefaultJob(conf=job_config,
                 task=DefaultTask(extractor=dExtractor, loader=FsNeo4jCSVLoader()),
                 publisher=Neo4jCsvPublisher())
job.launch()

You can check out the sample deltalake metadata script for a full example.

Mode Dashboard Extractor

Here are extractors that extracts metadata information from Mode via Mode's REST API.

Prerequisite:
