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: N/A
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".
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:
A
/ \
B C
\ /
D
The Table List will output the following documents:
This Snap uses account references created on the Accounts page of SnapLogic Manager to handle access to this endpoint. See Configuring Vertica Accounts for information on setting up this type of account.
Views:
Input
This Snap has exactly one input view.
Output
This Snap has at most one output view.
Error
This Snap has at most one error view and produces zero or more documents in the view.
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. Selecting a schema filters the Table name list to show only those tables within the selected schema. The property is suggestible and retrieves available database schemas during suggest values.
Example: public
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. Note that as 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
Select one of the following three modes in which the Snap executes:
Validate & Execute: Performs limited execution of the Snap, and generates a data preview during Pipeline validation. Subsequently, performs full execution of the Snap (unlimited records) during Pipeline runtime.
Execute only: Performs full execution of the Snap during Pipeline execution without generating preview data.
Disabled: Disables the Snap and all Snaps that are downstream from it.
Default Value: Execute only Example: Validate & Execute
Examples
In this pipeline, the Vertica Table List Snap lists the tables present in the schema, 'public'.
