Configuration for PostgreSQL connection with production-hardening features

Fields

database_url: String

Database connection URL

max_connections: u32

Maximum number of connections in the pool

min_connections: u32

Minimum idle connections to maintain

connect_timeout: Duration

Connection timeout

query_timeout: Option<Duration>

Query timeout for individual database operations This is different from connection timeout and applies to query execution

max_lifetime: Option<Duration>

Maximum lifetime of a connection

idle_timeout: Option<Duration>

Idle timeout for connections

test_before_acquire: bool

Whether to test connections before use

max_retries: u32

Maximum number of retry attempts for failed operations

retry_base_delay: Duration

Base delay between retry attempts

retry_max_delay: Duration

Maximum delay between retry attempts (for exponential backoff)

enable_recovery: bool

Whether to enable connection recovery on failures

health_check_interval: Duration

Interval for periodic health checks

read_batch_size: usize

Batch size for reading events from multiple streams This controls how many events are fetched in a single query

serialization_format: SerializationFormat

Serialization format to use for event payloads Defaults to JSON for backward compatibility
