Read time 3 minutes
Last updated 3 months ago
Sessions support two types of custom data:
  • Session-scoped data is associated with the entire session and can include fields that are indexed for querying.
  • Player-scoped data is associated with a specific player in a specific lobby. Each player in the lobby can have different set properties.

  • Maximum properties: 20
  • Non-indexed: 2 KB / each

  • Maximum number of indexed strings: 5

  • Maximum size: 2KB

Data access and visibility

There are three levels of access to data:

Public data

  • Data that is visible to anyone, including players who are not in the session.
  • Examples of public data include maps and profile icons.

Member data

  • Data that is only visible to players who have joined the session.

Private data

  • Data that is only visible to an individual player who is in the session.
  • Session data that is only visible to the host, player data that is only visible to the owning player and the host.

Data access table

Depending on a player's role in the session (host, member, or non-member), they have different access restrictions to data:
