Data Sources Configuration

This article describes the properties used to configure data sources in Data Processing Engine (DPE). To modify the default configuration, add or edit properties in the Configuration Service or in the dpe/etc/application.properties file.

For an overview of recommended database versions, see ROOT:supported-third-party-components.adoc, section Databases.

JDBC data source plugin default configuration

These properties define default JDBC connection configuration for all data sources. You can also configure each driver separately, in which case driver-specific properties override the values provided here for that particular driver.

Each property follows the pattern plugin.jdbcdatasource.ataccama.one.connections.{propertyName}.

Property Data type Description

Property	Data type	Description
`plugin.jdbcdatasource.ataccama.one.connections.pooling-enabled`	Boolean	If set to true, connection pooling is applied. If the property is not set, the default value is `false`. If you use data source throttling by specifying `ataccama.one.dpm.resource-allocation.connections.<name>`. DPM properties, this property needs to be set to false for all connected DPEs.
`plugin.jdbcdatasource.ataccama.one.connections.connection-timeout`	Number	Defines for how long the pool manager or, in case connection pooling is not enabled, a data source, lets the client’s connection request wait before a timeout exception is thrown. This typically happens when all available connections are already in use and no new connections can be added due to other limits. Expressed in milliseconds. The default value is `20000` when connection pooling is not enabled or `30000` when connection pooling is applied.
`plugin.jdbcdatasource.ataccama.one.connections.idle-timeout`	Number	Specifies for how long a connection can remain idle in the connection pool before it is closed. Applicable if connection pooling is enabled. Expressed in milliseconds. Default value: `300000`.
`plugin.jdbcdatasource.ataccama.one.connections.max-lifetime`	Number	Determines for how long a connection can remain in the pool. The connections that are currently in use are not closed. Expressed in milliseconds. Applicable if connection pooling is enabled. The period should be several seconds shorter compared to the database limit. Default value: `900000`.
`plugin.jdbcdatasource.ataccama.one.connections.minimum-idle`	Number	The minimum number of idle connections in the pool. Applicable if connection pooling is enabled. If the property is not set, the value corresponds to the value of the property maximum-pool-size. Default value: `1`.
`plugin.jdbcdatasource.ataccama.one.connections.maximum-pool-size`	Number	The maximum number of connections in the connection pool. This includes both active and idle connections. Applicable if connection pooling is enabled. When the maximum number of connections is reached, further connection requests are blocked. If the property is not set, the number of allowed connections is `10`. Default value: `5`.
`plugin.jdbcdatasource.ataccama.one.row-count-timeout`	String	Specifies the maximum waiting time for row count operation during preprocessing. Default value: `119m`.

String

Specifies the maximum waiting time for row count operation during preprocessing.

Default value: 119m.

JDBC data source driver configuration

The following properties need to be set when configuring a JDBC Data Source Plugin. You can use these properties as a template for adding custom data sources. The property names follow this pattern: plugin.jdbcdatasource.ataccama.one.driver.{driverId}.{propertyName}. The identifier of the driver (driverId) needs to be unique and should match the identifier of the database, for example, postgresql.

It is also possible to add custom JDBC properties. To do this, use the pattern plugin.jdbcdatasource.ataccama.one.driver.{driverId}.properties.{propertyName} and replace all placeholder values.

For example, if you are working with an Oracle database with the default configuration and want to define how many rows are prefetched, the following property should be provided:

plugin.jdbcdatasource.ataccama.one.driver.oracle.properties.oracle.jdbc.defaultRowPrefetch

Or, if you need to log in as a system user in an Oracle database, the following property should be added:

plugin.jdbcdatasource.ataccama.one.driver.oracle.properties.oracle.jdbc.internal_logon=sysdba

Examples of configuration with default values are provided for the following data sources: Oracle, PostgreSQL, Amazon Aurora PostgreSQL, MySQL, Amazon Aurora MySQL, MSSQL, Azure Synapse Analytics, H2, MariaDB, Teradata, Amazon Redshift, Snowflake, Apache Cassandra, Big Query, and IBM Netezza. The H2 data source should only be used for testing purposes.

The properties related to connection pooling are driver-specific values of connection pooling properties that are defined for all drivers. The <driverId>.driver-class property must be added if there are multiple drivers found in the driver’s classpath (<driverId>.driver-class-path).

Property Data type Description

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.name

String

The name of the data source that is displayed in ONE Web Application.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.connection-pattern

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.schema-regex

String

A regular expression for a schema name from connection string in its first group.

This is especially useful for data sources where all schemas are listed regardless of the database specified in the connection string, such as Teradata (jdbc:teradata://.database=([a-zA-Z0-9_]).) or Cassandra (jdbc:cassandra://.?/().). The database name is then case-sensitive.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.driver-class-path

String

The classpath of the driver, for example, postgresql-*.jar.

To select multiple files, use a semicolon (;) as a separator.

If you are adding a non-default JDBC driver. In that case, you need to omit the provider-class property as well.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.provider-class

String

The customized implementation class of the driver’s provider. If the property is not provided, the default provider is used. Omitted if configuring a custom JDBC driver.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.pooling-enabled

Boolean

If set to true, connection pooling is applied.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.connection-timeout

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.idle-timeout

Number

Specifies for how long a connection can remain idle in the connection pool before it is closed. Applicable if connection pooling is enabled. Expressed in milliseconds.

Default value: 300000.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.max-lifetime

Number

Default value: 900000.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.minimum-idle

Number

The minimum number of idle connections in the pool. Applicable if connection pooling is enabled.

If the property is not set, the value corresponds to the value of the property maximum-pool-size.

Default value: 1.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.maximum-pool-size

Number

If the property is not set, the number of allowed connections is 10.

Default value: 5.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.full-select-query-pattern

String

A query pattern for displaying all records, for example, SELECT {columns} FROM {table}.

Allowed placeholders: {columns}, {table}.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.preview-query-pattern

String

A query pattern for displaying a preview of records, for example, SELECT {columns} FROM {table} WHERE ROWNUM ⇐ {previewLimit}.

Allowed placeholders: {columns}, {table}, {previewLimit}.

If the property is not set, the pattern SELECT {columns} FROM {table} is used instead.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.dsl-query-preview-query-pattern

String

A DSL query pattern for loading data source preview. The property is mainly used for optimization purposes.

By default, the pattern is as follows: SELECT * FROM ({dslQuery}) dslQuery LIMIT {previewLimit}.

Allowed placeholders: {dslQuery}, {previewLimit}.

For exact configuration details, refer to the corresponding section for your data source type on this page.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.dsl-query-import-metadata-query-pattern

String

A DSL query pattern for importing metadata. The property is mainly used for optimization purposes.

By default, the pattern is as follows: SELECT * FROM ({dslQuery}) dslQuery LIMIT 0 or SELECT * FROM ({dslQuery}) dslQuery WHERE 1=0 (for example, for Teradata).

Allowed placeholders: {dslQuery}.

For exact configuration details, refer to the corresponding section for your data source type on this page.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.row-count-query-pattern

String

A query pattern for counting the number of rows in a catalog item, for example, SELECT NUM_ROWS FROM ALL_TABLES WHERE TABLE_NAME = {table}.

Allowed placeholder: {table}.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.row-number-column

String

Allowed placeholders: {table}, {columns}, {limit}, {percentageLimit}.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.query-quotation-mark

String

The punctuation mark used to delimit identifiers in queries, typically a backtick () or a quotation mark (\"`), which needs to be escaped.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.disallowed-indexes-table-types

String

Restricts which table types can be queried in the data source.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.bulk-import-table-count-threshold

Number

If set, metadata is loaded in bulk for all tables available in a schema or database provided that the number of tables selected for import exceeds the threshold specified. Otherwise, the bulk import strategy is applied only when users attempt to load the whole schema (or, in data sources that do not use schemas, the whole database). In other words, if the property is omitted or not supported for the given data source, tables are processed and queried one by one.

The property is particularly useful when working with slow databases. For example, if querying metadata for a single table takes 2 minutes and for the full schema 5 minutes, setting the threshold to 5 should significantly reduce waiting time for users when importing more than 5 tables.

In the current version, the property can be used for the following data sources: MSSQL, Oracle, PostgreSQL, Amazon Aurora PostgreSQL.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.disabled

Boolean

Disables the JDBC driver. To do so, set the property to true. For example:

plugin.jdbcdatasource.ataccama.one.driver.mysql.disabled=true
plugin.jdbcdatasource.ataccama.one.driver.aurora-mysql.disabled=true
plugin.jdbcdatasource.ataccama.one.driver.redshift.disabled=true
plugin.jdbcdatasource.ataccama.one.driver.bq.disabled=true

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.location-query

String

Customizes the query to determine the location root.

The default value is data source dependent.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.schema-exclude-pattern

String

If set, any entity’s name matching this pattern is excluded from the job result.

This property is not used for the following data sources which do not support schemas: MySQL, Amazon Aurora MySQL, MariaDB. If you specify any value here, this would result in an empty job result.

Make sure that correct regular expression syntax is used (see Pattern (Java Platform SE 7). Otherwise DPE fails to run properly.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.schema-include-pattern

String

If set, only entity’s name matching this pattern is included in the job result.

This property is not used for the following data sources which do not support schemas: MySQL, Amazon Aurora MySQL, MariaDB. If you specify any value here, this would result in an empty job result.

Make sure that correct regular expression syntax is used (see Pattern (Java Platform SE 7). Otherwise DPE fails to run properly.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.table-exclude-pattern

String

If set, any entity’s name matching this pattern is excluded from the job result.

Make sure that correct regular expression syntax is used (see Pattern (Java Platform SE 7). Otherwise DPE fails to run properly.

plugin.jdbcdatasource.ataccama.one.driver.<driverId>.table-include-pattern

String

If set, only entity’s name matching this pattern is included in the job result.

Troubleshooting

Dremio error: Failure getting metadata

In case you encounter the following error Failure getting metadata: Number of fields in dataset exceeded the maximum number of fields of 800, this means you need to review and modify the configuration of wide table limits in Dremio. For more information, refer to the official Dremio documentation, specifically Creating and Querying Wide Tables.

BigQuery connection issues

When attempting to troubleshoot BigQuery connection issues, try the following:
Consult the ODBC and JDBC drivers for BigQuery documentation.
Consult the JDBC driver documentation. Included as a PDF in the downloaded JDBC driver ZIP file.
The recommended predefined Service Account roles used to access Big Query data are BigQuery Data Viewer (roles/bigquery.dataViewer) and BigQuery Job User (roles/bigquery.jobUser).
Pay attention to the Large Result Set Support section and the related AllowLargeResults, LargeResultDataset, and LargeResultTable properties.
If you are using a large result set:
- Make sure that the LargeResultDataset option is specified, the specified dataset exists, and is in the same region as the queried table.
- Otherwise, the Service Account used must have bigquery.datasets.create permissions on the BigQuery instance specified by the ProjectId property.
- Note that setting the LargeResultTable value causes all results to be written to the same table. However, the table creation time is not shown when the value is set.
If you are setting the OAuthPvtKeyPath driver property as a file path, for example, the key file is present on the DPE or the Runtime server:
- Set it directly as a JDBC string, not as a Driver property object.
- Make sure the user running the ONE platform (DPE or Runtime server) has read access to the key files .json and .p12.
Use LogLevel=6 and LogPath=<path> driver properties for the JDBC driver to create <path>/BigQuery…log files with detailed information about connecting to BigQuery, metadata processing, and SQL commands execution.

Azure SQL database token failure

Connecting to Azure SQL database fails with the following error:

MSI token failure

MSI Token failure: Failed to acquire access token from IMDS, verify your clientId

The error means that the clientId is either wrong or missing some required privileges. Verify the following in your environment:

Make sure that the Azure AD account is created within the Azure SQL server. The following example shows what the creation SQL queries look like. The user is in the table named sys.sysusers.
Creation SQL queries
```
CREATE USER name_of_the_user_managed_identity FROM EXTERNAL PROVIDER;
ALTER ROLE db_datareader ADD MEMBER name_of_the_user_managed_identity;
```
Make sure that in your Azure SQL server, the following property is enabled on the Set server firewall tab: Allow Azure services and resources to access this server.

On the virtual machine where your DPE is running, check Identity > User assigned. The managed identity should match the one in the JDBC string. Sample JDBC string:

Sample JDBC string

jdbc:sqlserver://host.database.windows.net:1433;encrypt=true;database=yourDB;encrypt=true;trustServerCertificate=false;loginTimeout=30;hostNameInCertificate=*.database.windows.net;authentication=ActiveDirectoryMSI;msiClientId=abcdxyz;

In most cases, completing the previous steps should be enough for DPE or any other external applications installed inside the VM to successfully connect to Azure SQL. If the problem still persists, try enabling the System assigned and remove msiClientId.
