options

options

Option	Type	Description	Default
causalConsistency	bool	Configure causal consistency in a session. If true, each operation in the session will be causally ordered after the previous read or write operation. Set to false to disable causal consistency. See » Casual Consistency in the MongoDB manual for more information.	true
defaultTransactionOptions	array	Default options to apply to newly created transactions. These options are used unless they are overridden when a transaction is started with different value for each option. options Option Type Description maxCommitTimeMS integer A quantidade máxima de tempo em milissegundos para permitir que um único comando commitTransaction seja executado. Se especificada, maxCommitTimeMS deve ser um inteiro de 32 bits com sinal com valor maior ou igual a zero. readConcern MongoDB\Driver\ReadConcern Um read concern a ser aplicado à operação. Esta opção está disponível no MongoDB 3.2+ e resultará em uma exceção em tempo de execução se for especificada para uma versão de servidor mais antiga. readPreference MongoDB\Driver\ReadPreference Uma preferência de leitura a ser usada para selecionar um servidor para a operação. writeConcern MongoDB\Driver\WriteConcern Um write concern a ser aplicado à operação. This option is available in MongoDB 4.0+.	[]
snapshot	bool	Configure snapshot reads in a session. If true, a timestamp will be obtained from the first supported read operation in the session (i.e. find, aggregate, or unsharded distinct). Subsequent read operations within the session will then utilize a "snapshot" read concern level to read majority-committed data from that timestamp. Set to false to disable snapshot reads. Snapshot reads require MongoDB 5.0+ and cannot be used with causal consistency, transactions, or write operations. If "snapshot" is true, "causalConsistency" will default to false. See » Read Concern "snapshot" in the MongoDB manual for more information.	false
