Constructor

new Collection(options)

Create a collection where you can manage and store your data.

Parameter	Default	Description
options		ObjectCollection options.
options.name		StringName of collection.
options.type		StringIMPORTANT Type of the collection, which cannot be changed again later.Valid values: DOCUMENT_BASED, KEY_VALUE_BASED
options.id_length	32	Number DOCUMENT-BASED COLLECTIONSThis determines the length of unique identities given to documents.
options.indicate_created_at	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the creation date of documents.
options.indicate_created_timestamp	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the creation timestamp of documents.
options.indicate_edited_at	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the edited date of documents.
options.indicate_edited_timestamp	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the edited timestamp of documents.
options.indicate_archived_at	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the archived at of documents.
options.indicate_archived_timestamp	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the archived timestamp of documents.
options.indicate_unarchived_at	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the unarchived at of documents.
options.indicate_unarchived_timestamp	false	Boolean DOCUMENT-BASED COLLECTIONSWhether to specify the unarchived timestamp of documents.
options.save_timeout	1	NumberThis specifies how many seconds after a document is inserted, the collection will be saved. This way it limits the successive saving of the collection when many data are inserted in succession, so the system is not slowed down. Data loss may occur if the system is turned off after repeatedly entering data. When the document is added 5 times in a row, the collection is saved so that the data does not remain unsaved for a long time. This can be edited with the 'save_directly_after' option.
options.save_directly_after	5	NumberThis specifies that after how many documents have been inserted, the collection will be saved without the save timeout.
options.cache_retention_time	10	NumberIf this value is -1, the cache is kept indefinitely This specifies how many minutes the cache will be retained if caching is enabled. If there is no activity in the collection, the cache is cleared, thus preventing RAM loss.
options.backup_retention_time	3	NumberIf this value is -1, backups will never be deleted This determines after how many days the backups will be deleted.
options.caching	false	BooleanIMPORTANT If this is enabled, the data is kept in the cache. In this case, the data is processed quickly, but the size of the collection is the loss of RAM. Is not preferred for large collections.
options.auto_create_backup	false	BooleanIf this is enabled, this collection will create automatic backups.
options.detailed_debugger_logs	false	BooleanIf this is enabled, it will print more events in the collection to the console.
options.activate_destroy_function	false	BooleanIMPORTANT If this is enabled, the <Collection>.Destroy() function becomes operable. This command serves to destroy your collection completely. It is a dangerous command.

const example_collection = new PeakDB.Collection({
  "name": "EXAMPLE_COLLECTION",
