To enhance your DataSync integration for Snowflake, you can configure the Snowflake Bulk Load Meshlet with the additional features available below!
Compare tables from ServiceNow to Snowflake
Table Compare allows you to compare tables from one ServiceNow instance to Snowflake. This is useful because you can see each table's record count, as well as a list of record discrepancies by sys_id between the two tables you're comparing—in other words, you can see which records exist in one table but not the other. To get started with comparing your ServiceNow tables to Snowflake, see Table Compare: ServiceNow to database table compare.
NOTE: This requires version Helium and above Perspectium Core update set.
Load Schema Files
This feature allows you to load your ServiceNow table schemas to the meshlet when a connection cannot be made to the originating ServiceNow instance. Schema files are used to create and update tables in Snowflake. Enabling this feature will force the meshlet to read schemas via files exclusively from the local file storage and disable all calls to ServiceNow. Any new tables shared will require table schemas to be added to the local file storage.
Export the table schemas in your ServiceNow instance. See Download Table Schemas.
Unzip the folder that was created from the previous step. Then, put the folder in the static/config directory.
The final location for each table should look like static/config/schemas/incident.xml.
In the application-dev.yml, set the following configurations:
perspectium: auth: useLocalSchema: true
NOTE: By default, useLocalSchema is set to false.
Azure External Storage
To start using Microsoft Azure as an external stage for bulk loading, follow these steps:
Configure bulk loading from Microsoft Azure by following configuring an Azure container for loading data.
In the application-dev.yml, set the following configurations:
| Directive | Description |
|---|---|
| url | Azure storage URL. perspectium: azure: url: azure://pspsnowflaketest.blob.core.windows.net/snowflakedev Where pspsnowflaketest is the storage account and snowflakedev is the container. |
| sasString | Shared Access Signatures (SAS) connection string for Azure Storage. See SAS connection string. To access the connection string, go to Storage Account > Account Name > Shared Access Signature. Then enter the required fields, and generate SAS and connection String. Allowed Resource Types:
Allowed Permissions:
perspectium: azure: sasString: ?sv=2020-08-04&ss…..ejl%2BTE%3D |
| connectionUrl | Connection URL for your Azure. To access the URL, go to Azure Portal > Storage Account > Access Keys > Show Keys > Connection String. perspectium: azure: connectionUrl: DefaultEndpointsProtocol=.....EndpointSuffix=core.windows.net |
| destinationContainer | Container you want to share your data to. perspectium: azure: destinationContainer: snowflakedev |
| deleteFiles | Stores files in Azure if necessary. perspectium: fileSubscriber: deleteFiles: true |
