IDBTransaction: durability property
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The durability read-only property of the
IDBTransaction interface returns the durability hint the transaction was
created with. This is a hint to the user agent of whether to prioritize performance or
durability when committing the transaction.
The value of this property is defined in the options parameter when creating a transaction using IDBDatabase.transaction().
Value
Any of the following literal strings:
"strict"-
The user agent may consider that the transaction has successfully committed only after verifying that all outstanding changes have been successfully written to a persistent storage medium.
"relaxed"-
The user agent may consider that the transaction has successfully committed as soon as all outstanding changes have been written to the operating system, without subsequent verification.
"default"-
The user agent should use its default durability behavior for the storage bucket. This is the default for transactions if not otherwise specified.
