Collections

Updated May 23, 2026

Collections in Qdrant are analogous to database tables. Dear Diary creates collections automatically when the first entry is stored.

Collection naming

Specify collections explicitly via the collection_name parameter, or configure a default via the COLLECTION_NAME environment variable. If neither is provided, store and find operations will fail with a missing collection error.

Multiple collections

Organize memories into separate collections for different purposes:

{
  "arguments": {
    "information": "Database migration script location: /scripts/migrate.sh",
    "collection_name": "infrastructure-notes"
  }
}
