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"`
	TS           int64       `json:"_ts"`
}

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

func (c *StateStore) Get(ctx context.Context, req *state.GetRequest) (*state.GetResponse, error)

Get retrieves a CosmosDB item.

func (*StateStore) GetComponentMetadata

func (c *StateStore) GetComponentMetadata() (metadataInfo contribmeta.MetadataMap)

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) MultiMaxSize

func (c StateStore) MultiMaxSize() int

MultiMaxSize returns the maximum number of operations allowed in a transaction. For Azure Cosmos DB, that's 100.

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)

func (*StateStore) Set

func (c *StateStore) Set(ctx context.Context, req *state.SetRequest) error

Set saves a CosmosDB item.
