For each Buffer required, you start by creating a basic Buffer within your own solution in the Synatic menu.
To create a basic Buffer:
The Buffer menu is located on your own Solutions menu.
To create a Buffer, click the + icon to open the Create Buffer dialog.

Buffer name
Type in a meaningful name for the Buffer and also a meaningful description.
At this point, you can enter some of the properties but they are not required just yet unless you know exactly what their selection should be.
You'll configure all the properties when Configuring the Buffer.
Properties
Indexes - Creating indexes helps improve performance against the buffer.
• Enables fast searches for lookups and queries.
• Click the + icon to add key index fields, a sort field, and a unique flag, or
• Click the </> icon to add key index fields using MongoDB Extended JSON specification code.Type - The type option lets you select the usage type for the data to be optimized in the Buffer.
The available types are:
• Data - Use this usage type if you are predominantly searching and reading data.
• Transactional - Use this usage type if you are predominantly reading and writing data.
• Log - Use this usage type if you are predominantly writing data.Cache Definition - This option sets a cache period for the Buffer definition in minutes.
• The definition only includes the buffer's defined metadata, schema, indexes, etc. but not the buffer's data.
• For example, if the cache period is set to five minutes, the Buffer definition will be re-cached in memory every five minutes.
• A setting of zero minutes implies that there will be no caching.Expire After (minutes) - This option sets a Time to Live (TTL) limit on the data in minutes.
• When the expiry time is reached, all records in the buffer that are older than the expiry minutes will be deleted.
• A setting of zero will not delete any records from the Buffer.Save Buffer - Click Save to conclude.
