Platform Limits

The following limits exist to ensure the optimum performance of the Lytics platform and your connected sites, data sources, and applications. The tables contain default limits for all accounts unless stated otherwise. If you have questions, please get in touch with your Lytics Account Manager.

Events

An event is any action or activity a user performs, any update to a profile, or any export out of the subscription services.

Resource	Limit	Description
Max input size	4 KB	Byte size of a single input record.
Max size in batch	16 KB	Byte size of a single input record within a batch.
Max size total batch	1 GB	Byte size of all records within a batch.

User Profiles

A User Profile is the living record of an individual that interacts with your brand. Lytics user profiles provide a view of your customers across your connected channels.

Known profiles have at least one known identifier such as an email or CRM ID.
Anonymous profiles have only anonymous identifiers such as a cookie ID.

Resource	Limit	Description
Max size of a user profile	1 MB	Byte size of a single user profile.
Max size of a profile identifier	256 bytes	Unique identifiers are used to merge data fragments together into a single user profile. Read more about Profile Stitching Best Practices.
Max number of user attribute values on a profile	1,000	Values include individual items in complex field types such as maps and sets. E.g. if a user has 100 values for the field `URLs_visted`, only 900 values remain for the total count.
Max aggregate size of all user profiles	Quota based on pricing	Total size of all user profiles.
Max number of custom mapped fields	Quota based on pricing	Custom mapping of fields through Queries & LQL.
Max stitched Identifiers	50	“Stitched” identifiers can be used to look up a user such as email or user ID.

Browsers and Cookies

The following limits apply to client-side integrations, which are implemented in browser-facing code through the Lytics JavaScript tag and typically a third-party tag as well.

Resource	Limit	Description
Max number of audiences stored as a cookie	5 MB	Browsers limit the max size of the sum of all cookies. This limit only applies to Lytics JavaScript Tag version 2, as version 3 uses local storage instead of a cookie.

Maximum size of collect payload sent via URL	2,000 bytes	Try to keep payload sizes small enough to fit in a URL using GIF transport. If the GIF limit is exceeded, the payload will be sent via iframe transport, which can result in poor performance.

Integrations

Max number of active import integrations	100	Import integrations ingest data such as user profiles, activity data, and subscription status from third-party tools into Lytics.
Max number of active export integrations (“subscriptions”)	200	Export integrations send user profile data from Lytics to a third-party tool, usually at the audience level. Raw event data or metrics can also be exported for monitoring.
Max integrations creations per hour	10	This limit applies to all server-side integrations, including imports, exports, and any other workflow, such as enrichment integrations.
