Description
Count distinct attendeeIds by exact string equality; repeatRecords equals list length minus distinct count.
Extension-service records track resources, attendance, feedback and permission assertions. Distinct people and repeated records have different denominators, and a complete record does not prove valid consent or a high-quality service. Names such as verified describe caller-supplied evidence flags.
Count distinct attendeeIds by exact string equality; repeatRecords equals list length minus distinct count.
When to use this tool
Use Field Day Attendance Repeat Count when checking the stated extension-service record, participation or permission convention.
How to use the tool and how it works
- Enter attendeeIds. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read uniqueAttendees, repeatRecords. Use the output convention below.
Count distinct attendeeIds by exact string equality; repeatRecords equals list length minus distinct count.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| attendeeIds | Attendee Ids | Required. Array of text; maximum UTF-16 length 8192; maximum items 256. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| uniqueAttendees | Unique Attendees | Required. Safe integer. |
| repeatRecords | Repeat Records | Required. Safe integer. |

"attendeeIds": [

]
},
"output": {
"uniqueAttendees": 2,
"repeatRecords": 2
}
}Limitations and assumptions
- Repeated IDs are not necessarily repeat people or repeat attendance events; identity resolution is not performed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
Alternative or Complementary methods
Review original service and participant records and the applicable permission/organizational rules for actual use or reporting decisions.
