Overview

Package cache provides support for caching Access API calls.

Functions

func Context

func Context(parent context.Context, callerID string) context.Context

Context returns a new context annotated with the given caller ID.

func Skip

func Skip(parent context.Context) context.Context

Skip returns a context that will bypass the cache. If the context is already a skip context, it will be returned as is.

Types

type Store

type Store struct {
	// contains filtered or unexported fields
}

Store caches gRPC API responses from the Access API servers.

The key for each entry is made up by hashing together the request method and message using BLAKE3. And the value is the protobuf-encoded response value.

func New

func New(dir string) *Store

New opens the database at the given directory and returns the corresponding Store.

func (*Store) DropAll

func (s *Store) DropAll() error

DropAll drops all data stored in the underlying cache database.

func (*Store) InterceptUnary

func (s *Store) InterceptUnary(ctx context.Context, method string, req, res interface{}, cc *grpc.ClientConn, invoker grpc.UnaryInvoker, opts ...grpc.CallOption) error

InterceptUnary implements the gRPC middleware for caching certain Access API calls.
