Before using DataArts Studio, you need to select cloud services or databases as the data foundation, which provides storage and compute capabilities. DataArts Studio provides one-stop data development, governance, and services based on the data foundation.

Supported Data Sources

This section describes the data sources supported by DataArts Studio modules other than DataArts Migration. Table 1 lists the data sources supported by each module.

Except DataArts Migration, all other modules use the data connections created in Management Center. (A data connection can be used in a module which was selected during the creation of the connection.) To connect to these data sources, go to the DataArts Studio console and choose Management Center to create data connections.

NOTE:

The data sources supported by the migration jobs in DataArts Migration are different from those supported by other modules, and are described in the DataArts Migration chapter. Migration jobs include CDM jobs, offline jobs, and real-time jobs. They support the following data sources:

CDM jobs use the data connections created in CDM clusters. The data sources supported by CDM jobs are related to the CDM cluster version. For details, see Data Sources Supported by CDM Jobs.
Offline migration jobs use the data connections for which DataArts Migration has been selected for Applicable Modules in Management Center. For details, see Data Sources Supported by Offline Migration Jobs.
Real-time migration jobs use the data connections for which DataArts Migration has been selected for Applicable Modules in Management Center. For details, see Supported Data Sources.

Annotation

[1] MRS Spark: MRS Spark connections can be used to integrate data into the DataArts Architecture and DataArts Quality modules. MRS Hudi is a data format. The metadata is stored in Hive, and operations are performed using Spark. DataArts Catalog uses MRS Hive to collect Hudi metadata, and DataArts Architecture and DataArts Quality use MRS Spark to govern Hudi data sources. (Business metric monitoring of DataArts Quality does not support Hudi data sources.)

[2] DataArts Catalog: In addition to the data sources listed in the preceding table, DataArts Catalog can also collect metadata of the following data sources:

Relational databases, such as MySQL and PostgreSQL databases (You can use RDS connections to collect the metadata of these databases.)
Cloud Search Service (CSS)
Graph Engine Service (GES)
Object Storage Service (OBS)
MRS Hudi (MRS Hudi is a data format. The metadata is stored in Hive, and operations are performed using Spark.) You can enable synchronization of the Hive table configuration for Hudi tables, and then you can collect the metadata of Hudi tables by collecting the MRS Hive metadata.

[3] DataArts Quality: The quality jobs and comparison jobs of DataArts Quality are not supported by MRS clusters with decoupled storage and compute.

Overview

**Table 2** Data source overview
Data Source Type	Description
DWS	HUAWEI CLOUD DWS employs the shared-nothing architecture and massively parallel processing (MPP) engine. It is compatible with ANSI SQL 99, SQL 2003, and the PostgreSQL or Oracle database ecosystem, providing competitive solutions for analyzing petabytes of data in various industries.
DLI	HUAWEI CLOUD DLI is a serverless big data compute and analysis service that is fully compatible with Apache Spark and Apache Flink ecosystems. With multi-model engines supported by DLI, enterprises can use SQL statements or programs to easily complete batch processing, stream processing, in-memory computing, and machine learning of heterogeneous data sources.
MRS HBase	HBase undertakes data storage. It is an open-source, column-oriented, distributed storage system that is suitable for storing massive amounts of unstructured or semi-structured data. It features high reliability, high performance, and flexible scalability, and supports real-time data read/write. MRS HBase stores massive amount of data and supports data queries in milliseconds. MRS HBase can load and update logistics data in milliseconds, and query and analyze petabytes of time series data in seconds.
MRS Hive	Hive is a mechanism that can store, query, and analyze large-scale data stored in Hadoop. Hive defines simple SQL-like query language, which is known as HiveQL. It allows a user familiar with SQL to query data. MRS Hive can be used to analyze terabytes or petabytes of data and quickly migrate on-premises Hadoop big data platforms (such as CDH and HDP) to the cloud without service interruption and service code modification.
MRS Kafka	HUAWEI CLOUD MRS provides dedicated MRS Kafka clusters. Kafka is an open-source, distributed, partitioned, and replicated commit log service. Kafka is publish-subscribe messaging, rethought as a distributed commit log. It provides features similar to Java Message Service (JMS) but another design. It features message endurance, high throughput, distributed methods, multi-client support, and real time. It applies to both online and offline message consumption, such as regular message collection, website activeness tracking, aggregation of statistical system operation data (monitoring data), and log collection. These scenarios engage large amounts of data collection for Internet services.
MRS Spark	Spark is an open-source parallel data processing framework. It helps users easily develop unified big data applications and perform cooperative processing, stream processing, and interactive analysis on data. Spark provides a framework featuring fast calculation, write, and interactive query. Spark has obvious advantages over Hadoop in terms of performance. Spark provides the Spark SQL language similar to SQL statements to process structured data.
MRS ClickHouse	ClickHouse is an open-source columnar database oriented to online analysis and processing. It is independent of the Hadoop big data system and features ultimate compression rate and fast query performance. In addition, ClickHouse supports SQL query and provides good query performance, especially the aggregation analysis and query performance based on large and wide tables. The query speed is one order of magnitude faster than that of other analytical databases. ClickHouse is widely used in various fields such as Internet advertising, apps, web, telecommunications, finance, and IoT. It suits business intelligence ideally.
MRS Impala	Impala provides fast, interactive SQL queries directly on your Apache Hadoop data stored in HDFS, HBase, or the Object Storage Service (OBS). In addition to using the same unified storage platform, Impala also uses the same metadata, SQL syntax (Hive SQL), ODBC driver, and user interface (Impala query UI in Hue) as Apache Hive. This provides a familiar and unified platform for real-time or batch-oriented queries. Impala is an addition to tools available for querying big data. Impala does not replace the batch processing frameworks built on MapReduce such as Hive. Hive and other frameworks built on MapReduce are best suited for long running batch jobs.
MRS Ranger	Ranger offers a centralized security management framework and supports unified authorization and auditing. It manages fine-grained access control over Hadoop and related components, such as HDFS, Hive, HBase, Kafka, and Storm. You can use the frontend web UI console provided by Ranger to configure policies to control users' access to these components.
MRS Hudi	Hudi is a data lake table format that provides the ability to update and delete data as well as consume new data on HDFS. It supports multiple compute engines and provides insert, update, and delete (IUD) interfaces and streaming primitives, including upsert and incremental pull, over datasets on HDFS. Hudi metadata is stored in Hive, and operations are performed using Spark.
MRS Presto	Presto is an open-source SQL query engine for running interactive analytic queries against data sources of all sizes. It applies to massive structured/semi-structured data analysis, massive multi-dimensional data aggregation/report, ETL, ad-hoc queries, and more scenarios. Presto allows querying data where it lives, including HDFS, Hive, HBase, Cassandra, relational databases, or even proprietary data stores. A Presto query can combine different data sources to perform data analysis across the data sources.
MRS Doris	Doris is a high-performance, real-time analytical database. It can return query results of mass data in sub-seconds and can support high-concurrency point queries and high-throughput complex analysis. Apache Doris can meet requirements in report analysis, instant query, unified data warehouse building, and data lake federated query.
RDS	HUAWEI CLOUD RDS is an online, out-of-the-box relational database service that is based on the cloud computing platform. It is stable, reliable, scalable, and easy to manage.
MySQL	MySQL is one of the most popular open-source databases. It features excellent performance, uses mature and stable architecture, supports popular applications, adapts to multiple fields and industries, and supports various web applications. It is cost-effective and preferred by small- and medium-sized enterprises.
Oracle	Oracle is a group of software that mainly applied to the distributed database. The Oracle database is one of the most popular Client/Server (C/S) and Browser/Server (B/S) databases. It is also the most widely used database management system in the world. As a general database system, the Oracle database provides complete data management functions. As a relational database, it provides complete relational models. As a distributed database, it implements distributed data processing.
DIS	DIS streams are used to schedule jobs between workspaces. If DIS streams are used, messages can be sent to the DIS streams of another account. Otherwise, messages can be sent only to streams in all regions of the current account.
Rest Client	The Rest Client can be used to execute RESTful requests that are authenticated using IAM tokens or usernames and passwords.
Host Connection	You can connect to a specified host during data development and execute shell or Python scripts on the host through script development and job development. If the host connection information changes, you only need to edit it on the Host Connections page, but do not need to edit it in scripts or jobs one by one.
