Added

• Added postgres.NewFromDB() for constructing a driver from an existing *sql.DB.
• Added dynamodb.NewFromClient() and s3.NewFromClient() for constructing drivers from existing AWS SDK clients.

Changed

• [BC] Moved Driver and Config interfaces to the driver package; the root package re-exports them as type aliases.
• [BC] Changed New() in each driver package to accept *Config instead of individual parameters.

Added

• Added Driver interface providing access to journal.BinaryStore, kv.BinaryStore, and set.BinaryStore from a single driver.
• Added Config interface with a NewDriver(context.Context) (Driver, error) method for constructing drivers from configuration.
• Added ParseURL() and FromURL() for constructing a Config from a URL string or *url.URL.
• Added memory, postgres/postgresql, dynamodb, and s3 driver packages, each with a Config struct, New(), ParseURL(), and FromURL() constructors.

Changed

• [BC] Reorganized AWS driver packages under driver/aws/dynamodb/ and driver/aws/s3/ to mirror the existing driver/sql/postgres/ structure.
• Updated to Go 1.26.

Added

• [BC] Added Provision() method to journal.Store, kv.Store, and set.Store interfaces, allowing callers to trigger infrastructure provisioning ahead of time.

Added

• Added s3kv package, an S3-backed implementation of kv.BinaryStore.
• Added s3set package, an S3-backed implementation of set.BinaryStore.
• Added journal.AdaptiveSearch() and journal.AdaptiveProbeFunc for probe-guided journal searches.

Changed

• [BC] Changed kv.Revision from a uint64 to an opaque string type.
• [BC] Changed kv.Keyspace.Set() to return the new Revision on success.
• Changed telemetry metric names to include a persistence.<subsystem>. prefix.

Added

• Added journal.WithNameTransform(), kv.WithNameTransform() and set.WithNameTransform(), which transform the apply a function to transform the name of each journal, keyspace and set, respectively.

Changed

• [BC] Changed keyspace revisions to use new kv.Revision type instead of uint64.
• [BC] The pgkv package now uses bias-encoded revisions, stored in PostgreSQL as signed BIGINT values (PostgreSQL's largest integer type), offering access to the full range of uint64 values.

This release adds revision-based OCC support to the kv package.

• Keyspace.Get() now returns the current revision of the key/value pair.
• Keyspace.Set() now requires the current revision to be passed as an argument, otherwise a ConflictError is returned.
• Added Keyspace.SetUnconditional(), which has the same semantics as Set() prior to this version.

Added

• Added set.WithInterceptor() to allow intercepting operations on sets.
• Added kv.WithInterceptor() to allow intercepting operations on keyspaces.
• Added journal.WithInterceptor() to allow intercepting operations on journals.

Removed

• [BC] Removed hooks from memoryset.Store and BinaryStore. Use set.WithInterceptor() instead.
• [BC] Removed hooks from memorykv.Store and BinaryStore. Use kv.WithInterceptor() instead.
• [BC] Removed hooks from memoryjournal.Store. Use journal.WithInterceptor() instead.

Added

• Added set.Set.Range() method to iterate over all members of a set.

Changed

• [BC] Renamed pgset table from set_value to set_member to match terminology elsewhere.
• [BC] Renamed dynamoset attribute from V (value) to M (member) to match terminology elsewhere.

Changed

• Change telemetry to use enginekit/telemetry package.
