Snap Type:

Read

Description:

This Snap outputs a list of tables in a database. The Snap will connect to the database, read its metadata, and output a document for each table found in the database. The table names are output in a topological order so that tables with the fewest dependencies are output first. In other words, if table A has a foreign key reference to table B, then table B will be output before A. The ordering is intended to ease the process of replicating a group of tables from one database to another.

Expected input: [None]
Expected output: Documents with the following fields:

- name - The fully-qualified name of the table. To use the table name in another Snap, like a Select or Insert, you can pass it through a ForEach Snap to another pipeline with the Select or Insert.
- type - The type of table. This value is currently fixed to the string "TABLE".
- dependents - (If Compute table graph is selected) A list of table names that have references to this table, including this table.

Replicating a Subset of Tables

The output of the Table List Snap can be directly used to replicate an entire database. However, if you are only interested in a subset of tables, you can use a Filter Snap to select the table names you are interested in as well as the tables that they reference. For example, given the following diamond-shaped table graph where A depends on B and C and they both depend on D:

The Table List will output the following documents:

name=D; dependents=[A, B, C, D]
name=C; dependents=[A, C]
name=B; dependents=[A, B]
name=A; dependents=[A]

So, if you wanted to copy just table 'A' and its dependencies, you can add a Filter Snap with the following expression:

 $.dependents.indexOf('A') != -1

The filter will then remove any extra tables that happen to be in the schema.

ETL Transformations & Data Flow

This snap is a data source. It works by performing a standard JDBC DatabaseMetaData#getTables() query for the tables within the database. The Schema name value is used to populate the schemaPattern parameter in that query.

This snap does not require any temporary files or other external resources.

Input & Output

Input: [None]

Any input documents are ignored.
- Input Schema Provided: No
- Output: This snap produces one document per table upon successful execution. The fields are:
- - name - The fully-qualified name of the table. To use the table name in another Snap, like a Select or Insert, you can pass it through a ForEach Snap to another pipeline with the Select or Insert.
  - type - The type of table. This value is currently fixed to the string "TABLE".
  - dependents - (If Compute table graph is selected) A list of table names that have references to this table, including this table.
- Output Schema Provided: Yes
- Preview Supported: Yes
- Passthrough Supported: No
- Output Examples:
  - Example output upon successful execution without Compute table graph selected:
    [ { "name": "\"demo\".\"'redshiftbulkload'\"", "type": "TABLE" }, { "name": "\"demo\".\"'shankaradp'\"", "type": "TABLE" }, { "name": "\"demo\".\"'shankaradp1'\"", "type": "TABLE" }, { "name": "\"demo\".\"'shankardemo'\"", "type": "TABLE" }, { "name": "\"demo\".\"'shankardemo1'\"", "type": "TABLE" } ]
  - Example output upon successful execution with Compute table graph selected:
    { "name": "\"demo\".\"account\"", "type": "TABLE", "dependents": [ "\"demo\".\"account\"" ] }, { "name": "\"demo\".\"account_transaction\"", "type": "TABLE", "dependents": [ "\"demo\".\"account_transaction\"" ] }, { "name": "\"demo\".\"accounts_oy\"", "type": "TABLE", "dependents": [ "\"demo\".\"accounts_oy\"" ] } ]

Expected upstream Snaps: Any Snap with a document output view. Note: the contents of the input view are ignored so pipelines should only be used to sequence operations.

Expected downstream Snaps: Any Snap with a document input view, such as JSON Formatter, Mapper, and so on. The CSV Formatter Snap cannot be connected directly to this Snap since the output document map data is not flat.

Modes

Ultra Pipelines: Works in Ultra Pipelines.

Prerequisites:

The Redshift account does need to specify the Endpoint, Database name, Username, and Password.
The Redshift account does not need to specify the S3 Access-key ID, S3 Secret key, S3 Bucket, and S3 Folder.
The Redshift account security settings does need to allow access from the IP Address of the cloudplex or groundplex.

Limitations and Known Issues

If you use the PostgreSQL driver (org.postgresql.Driver) with the Redshift Snap Pack, it could result in errors if the data type provided to the Snap does not match the data type in the Redshift table schema. Either use the Redshift driver (com.amazon.redshift.jdbc42.Driver) or use the correct data type in the input document to resolve these errors.

Configurations:

This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Redshift Account for information on setting up this type of account.

Views:

Input

This Snap has at most one document input view.

All input documents are ignored.

Output

This Snap has exactly one document output view.

The output document contains map data:

a "name" field containing the fully-qualified name of the table.
a "type" field containing the type of table. This is currently limited to "TABLE".
an optional "dependents" field containing a list of tables with foreign references to this table.

Error

This Snap has at most one document error view and produces zero or more documents in the view.

Troubleshooting: None.

Settings

Label

Required The name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Schema name

The database schema name. In case it is not defined, then the suggestion for the table name will retrieve all tables names of all schemas. The property is suggestible and will retrieve available database schemas during suggest values.

This field appears to support expressions but does not.

Example: test

Default value: [None]

Expression property: No

Compute table graph

Computes the dependents among tables and returns each table with a list of tables it has foreign key references to. The ordering of outputted tables is from least dependent to most-dependent.

Turning on this option will significantly slow down the Snap; it should be left as off unless you need it.

Default value: Not selected

Snap Execution

Default Value: Validate & Execute
Example: Execute only

Select an option to specify how the Snap must be executed. Available options are:

Validate & Execute: Performs limited execution of the Snap (up to 50 records) during Pipeline validation; performs full execution of the Snap (unlimited records) during Pipeline execution.
Execute only: Performs full execution of the Snap during Pipeline execution; does not execute the Snap during Pipeline validation.
Disabled: Disables the Snap and, by extension, its downstream Snaps.

Troubleshooting

Error	Reason	Resolution
`type "e" does not exist`	This issue occurs due to incompatibilities with the recent upgrade in the Postgres JDBC drivers.	Download the latest 4.1 Amazon Redshift driver here and use this driver in your Redshift Account configuration and retry running the Pipeline.

Examples

The Redshift - Execute Snap now includes a new Query type field. When Auto is selected, the Snap tries to determine the query type automatically. Behavior Change Starting with `version main22460`, in the Redshift Select Snap: When you create a table in Redshift, by default, all column names are displayed in lowercase in the output.

This upgrade is backward-compatible. The existing pipelines will continue to work as expected and the new pipelines will use the Redshift Driver as the default driver. SnapLogic will support providing fixes for the issues you might encounter with accounts that use the PostgreSQL driver only until November 2023. After November 2023, SnapLogic will not provide support for the issues with the PostgreSQL driver. Therefore, we recommend you to migrate from the PostgreSQL JDBC driver to the Redshift JDBC driver. Learn more about migrating from the PostgreSQL JDBC Driver to the Amazon Redshift Driver.
