Catalog Limitations – Iterable Support Center

NOTE

To add Catalog to your Iterable account, talk to your customer success manager.

This article describes some limitations of Iterable's Catalog feature.

# In this article

Organizations must store no more than 15GB of catalog data across all their Iterable projects.
Catalog names must be unique (regardless of case).
Catalog names may contain letters, numbers, and dashes (no spaces, underscores, or other special characters) and must be 255 characters or less.
It is not possible to rename a catalog.

Each catalog item must be less than 30kb.
In a given catalog, each catalog item must have a unique key (case sensitive).
In catalog item field names, periods are disallowed (for example, first.name is not a valid field name).
In a given catalog, there can be no more than 350 unique catalog item fields/columns.
The JSON viewer will incorrectly render catalog items containing a length field. Use tabular view instead.
The JSON editor will incorrectly render catalog items containing a length field. Use the text editor to edit these items.
Iterable's web interface can page through 30,000 catalog items or fewer. If the item you are looking for is deeper in the list than that, try changing the sorting order.
A CSV file containing catalog items must be no longer than 1000 rows, excluding the header row.
A CSV file containing catalog items must only contain data of type string, date, boolean, double, and long.
Once a field has been assigned a data type, it cannot be changed.
A catalog item's key field may contain letters, numbers, and dashes (no spaces, underscores, or other special characters) and must be 255 characters or less.

A collection can return at most 50 items.
It is not possible for a collection to search catalog item fields that do not have explicitly assigned data types.
Once a catalog item field has been given a data type, collections can search that field on all future data added to the same catalog. To search that field in previously created data, you must re-create or re-upload that data.
Collection definitions do not support Handlebars expressions.
The JSON view of a Collection Builder preview does not correctly render catalog items that contain a length field. To view this data, use tabular view instead.
