Struct mz_persist::postgres::PostgresConsensusConfig

pub struct PostgresConsensusConfig {
    url: SensitiveUrl,
    knobs: Arc<dyn PostgresClientKnobs>,
    metrics: PostgresClientMetrics,
}

Configuration to connect to a Postgres backed implementation of Consensus.

Fields

url: SensitiveUrl

knobs: Arc<dyn PostgresClientKnobs>

metrics: PostgresClientMetrics

Implementations

impl PostgresConsensusConfig

const EXTERNAL_TESTS_POSTGRES_URL: &'static str = "MZ_PERSIST_EXTERNAL_STORAGE_TEST_POSTGRES_URL"

pub fn new( url: &SensitiveUrl, knobs: Box<dyn PostgresClientKnobs>, metrics: PostgresClientMetrics, ) -> Result<Self, Error>

Returns a new PostgresConsensusConfig for use in production.

pub fn new_for_test() -> Result<Option<Self>, Error>

Returns a new PostgresConsensusConfig for use in unit tests.

By default, persist tests that use external storage (like Postgres) are no-ops so that cargo test works on new environments without any configuration. To activate the tests for PostgresConsensus set the MZ_PERSIST_EXTERNAL_STORAGE_TEST_POSTGRES_URL environment variable with a valid connection url 1.
