Amazon S3 Parquet

This article describes the three main steps required to create an Amazon S3 Parquet Collector:

• Providing read access for Anodot using a bucket policy (see below for more information)
• Creating an Amazon S3 Parquet Data Source
• Creating an Amazon S3 Parquet Stream Query

Creating an Amazon S3 Parquet Data Source

1. In the Navigation Panel, go to Integrations > Catalog. 
2. Use the Search box OR click the Storage filter to locate the data source.
3. Hover over the Amazon S3 Parquet tile, and click Start.
   Note: If the data source has already been used, a dialog is displayed in which you can select from one of the listed sources. Alternatively, create a new source by clicking Add a new source.
   
4. In the displayed dialog, select a bucket region, enter the bucket name, and enter a folder name (optional).
   
   
   
5. Setup the AWS bucket policy (see below) to enable anodot.com to access your S3 bucket.
6. Click CONTINUE to display the Stream Query window, as shown in the following section. 

Creating an Amazon S3 Parquet Stream Query

1. In the Sources page (accessed by clicking Integrations > Sources in the Navigation Panel), filter the list of streams to find the Amazon S3 Parquet source for which you want to create a stream query.
   Note: The streams associated with that source are displayed. If the Streams panel is empty, no stream queries exist for that source.
2. Hover over the Amazon S3 Parquet data source, and click + New Stream. The Stream Query page is displayed. 
   
   
   
   
3. In the Stream Properties section, set a name and owner for the stream.
4. In the Files to Collect section, define an (Optional) Root Path (such as example-month-il) and the Daily Partition Pattern (such as {{DD}}-{{MM}}-{{YYYY}}). 
5. In the File Properties section, define a Format (by default, Parquet is selected), and Compression (choose from None or Snappy).
   Note: Non-Parquet files cannot be uploaded to the Parquet files directory.
   
6. Click the Measures & Dimensions edit icon to define measures for the stream.
   
   
   - To add an item, drag from the Available fields repository on the left to the relevant Measures or Dimensions panel. At least one dimension and one measure [a numerical value] are required.
   - Select a time format from the dropdown menu, and then select a time zone.
   - When finished, click X to accept the edits and return to the Stream Query window.
   
   
7. Click the Schedule File Collection edit icon to define file collection settings for the stream.
   
   
   Define the following:
   - Set the collection interval in the Collect Files Every field.
   - Set the scheduling time zone of the data records time zone in the Files Time Zone field.
   - Set the delay according to the time it takes the data to be available in the Delay (Minutes) field.
   - Set a time span in the Ignore Files Older Than field. 
   - Set the number of intervals to waits for lagging files in the Lagging Files Policy field.
   
   For further details on the above fields and their settings, see Editing a Stream Query.
   
   
8. Click X to confirm the scheduling settings.
9. Click NEXT. The Stream Table is displayed, as described in Stream Tables.
