Format Level

Column Description
Format This column presents the names of formats.

Format names must be globally unique within the realm.

All names are limited to a maximum length of 256 characters.

Historical Version When you modify a deployed format definition by changing the number or names of fields, the FTL server creates a new version of the definition, and retains the old version. The FTL server retains older versions so that durable subscribers can still receive messages from the persistence store, even though those messages use older format versions.

You may explicitly delete an old format version if you are certain that it is no longer relevant: that is, the older version is no longer used by any publishing applications, nor by any messages within persistence stores.

Last Modified This timestamp indicates the date and time of the most recent change to this transport definition.
Description Optional.

This column presents a text field. You can annotate a format with a comment describing its usage.

Field Level

Column Description
Field This column presents the names of fields.

Field names must be unique within each format. (You may use the same field name in several different formats.)

Type Every field holds data of a specific data type.

Select a data type from the drop-down menu. For descriptions of the data types, see "Field Data Type Reference" in TIBCO FTL Development.
