Custom transactions

The Transaction object implements a builder pattern through TransactionBuilder

Restricted transactions

The Transaction::new pattern build a valid transaction for all collections (defined in the schema). You may want more restricted transactions, limited to a single Collection.

All structs deriving Record, here User, have access to:

• User::transaction building a transaction on this collection only.
• User::transaction_builder returning a builder for a transaction on this collection only.

Restricted transaction will fail if you try to Write on another collection.

Transaction options

The TransactionBuilder allows optional parameters:

• wait_for_sync, forcing the transaction to be synced to the database on commit.
• lock_timeout, specifying the transaction lock timeout (set to 60000 by default)
• collections, specifying the allowed collections (all collections are allowed by default)
