Import Data from Amazon Redshift

If you have your data stored in Amazon Redshift Cloud Database, then you can easily import your data into Zoho Analytics for reporting & analysis. Zoho Analytics allows you to either import the data into Zoho Analytics or connect directly with the Amazon Redshift server.

  • Data Import: Data in Amazon Redshift will be imported and stored in Zoho Analytics. You can setup periodic schedules to fetch the latest data automatically from your Amazon Redshift database. Report loading time will depend on the amount of data stored in Zoho Analytics.
  • Live Connect: In this mode, data will not be fetched from Amazon Redshift and stored in Zoho Analytics. Instead for the reports that you create, Zoho Analytics will generate appropriate queries. These queries will connect the required data live from Amazon Redshift to Zoho Analytics and show you the report. In this case, the loading time will directly depend on the performance of Amazon Redshift.

2. How do I import data from the Amazon Redshift?

3. How can I edit the setup?

4. How long does it take for the data to be imported into Zoho Analytics?

After setup, you might have to wait sometime for the initial fetch to happen. This depends upon the amount of data to be imported into Zoho Analytics and also the response time of your Amazon Redshift server. You will receive an email notification once the import is complete. Please note that, if you access the workspace before the initial fetch, it will not display any data.

5. Can I import data from Views created in Amazon Redshift (apart from Tables) into Zoho Analytics?

Yes, you can import data from both Views and Tables into Zoho Analytics. Zoho Analytics allows you to import data from tables, views, external tables, managed tables, and virtual views available in your Amazon Redshift database.

6. Will foreign keys defined between my tables in Amazon Redshift database be linked in Zoho Analytics as well?

When importing multiple tables, the foreign keys defined between the tables in Amazon Redshift database will be linked in Zoho Analytics. The foreign keys will be created as Look-up columns in Zoho Analytics. 

If you import data from one table at a time (choosing single table option) then the foreign keys will not be defined. However, you can manually link the tables in Zoho Analytics using the Look-up column feature. Click here to learn about the Look-up column feature.

7. Can I change the data type of the columns imported in Zoho Analytics?

Yes, you can change the data type of the columns imported into Zoho Analytics. However it is necessary that the data type of your column is compatible with the data type of the column in your Amazon Redshift database for successful data synchronizations. It is always recommended that you change the data type in both your Amazon Redshift database as well as your Zoho Analytics workspace.

8. I have connected to a database and imported a few tables into Zoho Analytics. Can I add more tables from the same source to the existing connection?

4. How is Live Connect different from Data Import?

Tabulated below are the differences between the Data Import feature and Live Connect feature.

Data ImportLive Connect
Data in Amazon Redshift will be imported and stored in Zoho Analytics.Data from Amazon Redshift will be fetched live using appropriate reporting queries whenever you create or access a report in Zoho Analytics.
Filtered data set can be imported from Amazon Redshift using customized queries.Custom Query feature is not available in Amazon Redshift Live Connect. However, you can create Views in the source database and connect the same with Zoho Analytics.
Multiple data sources (apart from Amazon Redshift) can be imported into the same workspace and they can be combined for reporting & analysis purpose.Cannot import data from any other data source into the same workspace in which Live Connect from Amazon Redshift is setup.
Changes made to the columns such as addition/deletion will be synchronized automatically.Any changes such as column addition/deletion/renaming will not be reflected. You will have to manually map the data using the Sync Design option.
When importing multiple tables, the foreign keys defined between the tables in the Amazon Redshift database will not be linked in Zoho Analytics. However, you can manually link the tables in Zoho Analytics using the Look-up column feature.Look-up relationship will be automatically created for tables that are linked via foreign keys in the Amazon Redshift database. You can also manually link the tables in Zoho Analytics using Look-up column feature.
Users can create query tables.Users cannot create query tables.
Report loading time will be fast as the data is stored in Zoho Analytics.Report loading time directly depends on the Amazon Redshift server response time and the amount of data in Amazon Redshift.

5. How long does it take for me to visualize my data in Zoho Analytics?

As there is no data import process involved, the loading time depends upon the amount of data stored in your Amazon Redshift database and also the response time of your Amazon Redshift server.

6. Will the reports/dashboards query hit my database server every time I open it or can it be cached in Zoho Analytics?
(or) Can I store a cache of my data points in Zoho Analytics to get quick access to my views?

Zoho Analytics allows you to create a cache for the reports in your live connect database to reduce the query fetching time.

To enable cache for your live connect workspace, please follow the below steps:

  1. From your Workspace Explorer, click Settings from the side menubar.
  2. In the General - Workspace Settings page that opens, choose Yes for Enable Cache for this Workspace.
  3. Provide Cache Refresh Interval in Minutes.
  4. Click Save & Close.

A cache for the reports will be created for the Workspace.

Note:
  • Enabling cache will help create a cache for your reports in the workspace. This data will get updated periodically based on the time provided in the Cache Refresh Interval in Minutes. 
  • You can create a cache only for the reports, and not for tables in the workspace.
  • This option is available only for Live Connect.

7. Can I connect Views created in Amazon Redshift (apart from Tables) to Zoho Analytics?

Yes, you can connect with both Views and Tables created in Amazon Redshift to Zoho Analytics.

8. Will foreign keys defined between my tables in Amazon Redshift database be linked in Zoho Analytics as well?

Yes. In case you have linked two or more tables in your Amazon Redshift database using foreign keys, they will be linked automatically using a Look-up column in Zoho Analytics as well. You can also manually create a lookup relationship among the imported tables in Zoho Analytics.

Note: The lookups created/modified in the added (linked with Zoho Analytics) tables will not be reflected in Zoho Analytics (even with Sync Design option). You need to manually create the lookup in Zoho Analytics. However, the lookup information will be created in Zoho Analytics when new tables are linked.

9. Can I link the related tables, connected from the Cloud Database using the Live Connect option, in Zoho Analytics?

Yes, you can link the related tables in Zoho Analytics using the lookup column feature. Learn more.

Note: 
  • You will not be able to create Query Tables if you have setup the workspace using the Amazon Redshift Live Connect option as this option does not fetch and store the data locally in Zoho Analytics.
  • The Join Tables (lookup column) option will not be available in the Import Wizard. You can create a lookup relation only on the imported tables.

10. I got an alert message like this - "This view cannot be accessed due to some changes made in the table" while accessing my tables/reports in Zoho Analytics. What should I do?

This alert message will be displayed when Zoho Analytics is not able to access the information from Amazon Redshift. This could be because the tables/columns that you are trying to access in Zoho Analytics are deleted or renamed in Amazon Redshift Cloud.

In this case, it is recommended that you remap the table/column. Refer to this presentation to know how to remap a table.

 

11. What is a Mismatch?

When you connect live with your Amazon Redshift database, it is necessary that the data (table names and column names) in the Zoho Analytics database and Amazon Redshift database matches. In case they do not match, they will be listed as a mismatch in the Mismatch tab in the Redshift Connection settings page. Mismatches can occur due to a variety of reasons. Please refer to the next question.

12. When do Mismatches occur and how to resolve them?

13. Can I synchronize a data table from my Cloud Database instantly?  

Yes, you can synchronize your data table from Cloud Database instantly when needed. 

To synchronize your data instantly:

  1. From the workspace explorer, click the Data Sources tab.
  2. You will get navigated to the Amazon Redshift Connection Settings page. All the tables available in the workspace will be listed.
  3. Mouse over the required table. The option to sync the table will be displayed inline to the table name.
  4. Click the Sync link inline to the table name.​
  5. The table data from the Cloud Database will get instantly synchronized in Zoho Analytics table. 
Note: You can also synchronize all the tables available in the workspace with your Amazon Redshift data using the Sync Design button.

14. Can I connect new columns added in my Amazon Redshift database to Zoho Analytics?

Yes, you can connect the new columns that are added in your Amazon Redshift database to Zoho Analytics from the Amazon Redshift​ Connection Settings page by following the below steps:

  1. From the workspace explorer, click the Data Sources tab.
  2. You will get navigated to the Amazon Redshift Connection Settings page. All the tables available in the workspace will be listed.
  3. Mouse over the required table. The option to sync the table will be displayed inline to the table name.
  4. Click the Sync link inline to the table name.

The data added in the particular table in your data source will be synced here. You can also synchronize all the tables available in the workspace with your Amazon Redshift data using the Sync Design button.

Note: If there exists a mismatch between the already available data in your Zoho Analytics workspace and your Amazon Redshift database, Zoho Analytics will NOT be able to fetch the new column information. In this case, you need to first resolve the mismatches to connect to the new columns.

15. Can I change the data type of the columns in Zoho Analytics?

No, you cannot change the data type of the columns in Zoho Analytics.

16. Can I import data from other data sources into the same workspace that I have used to connect with Amazon Redshift?

No, you cannot import data from other data sources into the same workspace that you have used to connect with Amazon Redshift.

17. Can I create Query Tables over the Amazon Redshift data?

No, you will not be able to create Query Tables if you have setup the workspace using the Amazon Redshift Live Connect option. This is because this option does not fetch and store the data locally in Zoho Analytics. If you wish to create Query Tables, you can create the required query as a view in the data source and connect the same with Zoho Analytics.

18. What happens when I delete or rename the database in Amazon Redshift?

When you delete or rename a database in Amazon Redshift, Zoho Analytics loses its connectivity with Amazon Redshift. Thereafter, a warning message, as shown below, would be displayed. This error message will also be displayed if there are any connectivity issues or if your Amazon Redshift Cloud credentials have expired.
​

For more information regarding the same, refer to the Edit Connection presentation.

19. How do I delete a view from a workspace?

You can easily delete a view from a live connect workspace, by following the below steps:

  1. Click the More Actions icon that appears on mouse-over the view name.
  2. Click the Delete option from the drop-down menu.
  3. You can also delete multiple views by selecting all the views that you want to delete and clicking the Delete option from the top.

The deleted views will be successfully removed from the workspace and placed in Trash. You can restore the views within 45 days of deletion from the Trash. After the mentioned timeframe, the views will get deleted permanently.

20. How to restore a deleted view in the workspace?

You can restore a deleted view from the workspace trash. To restore a deleted view, 

  1. Open the trash by clicking the Trash icon on the left menubar of the workspace.
  2. All the deleted views will be listed here. You can restore the required view by clicking the Restore icon that appears on mouse-over the view.
  3. You can restore multiple views by selecting the required views and clicking the Restore option from the top.
    ​
Note:

  • You cannot have two or more of the same tables with the same name in a workspace, hence you cannot restore a table if you have connected to the same table from the source database.

  • When you have two or more of the same tables in the trash, you can restore only one table. This instance occurs when you import and delete the same table multiple times.

21. How do I remove the Setup?

You have to delete the workspace in Zoho Analytics to remove the connection setup. 

To delete the workspace,

  1. From your Zoho Analytics account, click the More Actions icon that appears on mouse hover adjacent to the workspace name that you want to delete.
  2. Click the Delete Workspace option from the drop-down menu.

22. What are the limitations of using the Amazon Redshift Live Connect?

Given below are a few shortcomings that one might face while using the Amazon Redshift​​ Live Connect option.

  • Data from your Amazon Redshift database will NOT be locally stored in Zoho Analytics. Zoho Analytics will generate appropriate queries to fetch the required data live from Amazon Redshift and show you the report. Hence, the loading time will directly depend on the performance of Amazon Redshift Cloud.
  • Any changes such as column addition/deletion/renaming will not be mapped automatically. The user must manually map the updates made.
  • Users cannot combine data from other data sources into the same workspace in which you have connected the Amazon Redshift database. 
  • Users cannot create query tables.
  • Users cannot change the data type of the columns in Zoho Analytics.
