For each Buffer required, you start by creating a basic Buffer within your own solution in the Synatic menu.

To create a basic Buffer:

  1. The Buffer menu is located on your own Solutions menu.

  2. To create a Buffer, click the + icon to open the Create Buffer dialog.

Create Buffer

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.


  • 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.


The following option is available:
