Functions

func NewCosmosDBStateStore

func NewCosmosDBStateStore(logger logger.Logger) state.Store

NewCosmosDBStateStore returns a new CosmosDB state store.

Types

type CosmosItem

type CosmosItem struct {
	ID           string      `json:"id"`
	Value        interface{} `json:"value"`
	IsBinary     bool        `json:"isBinary"`
	PartitionKey string      `json:"partitionKey"`
	TTL          *int        `json:"ttl,omitempty"`
	Etag         string      `json:"_etag"`
}

CosmosItem is a wrapper around a CosmosDB document.

func NewCosmosItemFromResponse

func NewCosmosItemFromResponse(value []byte, logger logger.Logger) (item CosmosItem, err error)

type CosmosOperation

type CosmosOperation struct {
	Item CosmosItem          `json:"item"`
	Type cosmosOperationType `json:"type"`
}

CosmosOperation is a wrapper around a CosmosDB operation.

type InternalQuery

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

Internal query object is created here since azcosmos has no notion of a query object

type Query

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

func (*Query) Finalize

func (q *Query) Finalize(filters string, qq *query.Query) error

func (*Query) VisitAND

func (q *Query) VisitAND(f *query.AND) (string, error)

func (*Query) VisitEQ

func (q *Query) VisitEQ(f *query.EQ) (string, error)

func (*Query) VisitIN

func (q *Query) VisitIN(f *query.IN) (string, error)

func (*Query) VisitOR

func (q *Query) VisitOR(f *query.OR) (string, error)

type StateStore

type StateStore struct {
	state.BulkStore
	// contains filtered or unexported fields
}

StateStore is a CosmosDB state store.

func (*StateStore) BulkGet

func (c *StateStore) BulkGet(ctx context.Context, req []state.GetRequest, _ state.BulkGetOpts) ([]state.BulkGetResponse, error)

BulkGet performs a Get operation in bulk.

func (*StateStore) Delete

func (c *StateStore) Delete(ctx context.Context, req *state.DeleteRequest) error

Delete performs a delete operation.

func (*StateStore) Features

func (c *StateStore) Features() []state.Feature

Features returns the features available in this state store.

func (*StateStore) Get

Get retrieves a CosmosDB item.

func (*StateStore) GetComponentMetadata

func (c *StateStore) GetComponentMetadata() map[string]string

func (*StateStore) Init

func (c *StateStore) Init(ctx context.Context, meta state.Metadata) error

Init does metadata and connection parsing.

func (*StateStore) Multi

func (c *StateStore) Multi(ctx context.Context, request *state.TransactionalStateRequest) (err error)

Multi performs a transactional operation. Succeeds only if all operations succeed, and fails if one or more operations fail. Note that all operations must be in the same partition.

func (*StateStore) Ping

func (c *StateStore) Ping(ctx context.Context) error

func (*StateStore) Query

func (c *StateStore) Query(ctx context.Context, req *state.QueryRequest) (*state.QueryResponse, error)
