Once a new Buffer has been created and saved, the Buffer edit dialog is immediately opened as shown in the page below.

The edit dialog consists of four tabs:

Info Tab

View basic information about the Buffer. The Buffer size is displayed.

  • Recalc Size - Click to rescan and recount the actual number of records in the Buffer.

  • Purge - Click to delete all records from the Buffer. This action cannot be undone.

Indexes – Creating indexes helps improve performance against the Buffer and enables fast searches for lookups and queries. Click the New Index button to add key index fields, a sort field, and a unique flag.

Properties Tab

The following configuration is found in the Properties tab:

  • Type – Select the usage type for the data to be optimized in the Buffer. The available types are:

o Data - When searching and reading data.

o Transactional - When reading and writing data.

o Log - When writing data.

  • Cache Definition – 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) – 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.

Schema Tab

A schema is the structure that defines the objects in a database. The Schema tab provides functions to design and organize the data in a Buffer. The Schema objects are also used to populate the field drop-down lists.

  • Schema Viewer – Visualize the schema at different levels.

  • Regenerate Schema – Click to regenerate the Buffers schema from a random sample of data. This option will overwrite the currently defined schema.

  • Save Schema – Click to save the custom schema and all of the latest changes.

Save Buffer – Click the Save button to conclude.

Delete buffer – Click to delete the Buffer.
