Type Parameters:

K - the type of the key

All Superinterfaces:

ReactiveRedisCommands

All Known Implementing Classes:

ReactiveGraphCommandsImpl

public interface ReactiveGraphCommands<K>
extends ReactiveRedisCommands

Allows executing commands from the graph group. These commands require the Redis Graph module to be installed in the Redis server.

Method Detail

graphDelete

io.smallrye.mutiny.Uni<Void> graphDelete(K key)

Execute the command GRAPH.DELETE. Summary: Completely removes the graph and all of its entities. Group: graph

Parameters:

key - the key, must not be null

Returns:

a uni producing null when the operation completes

graphExplain

io.smallrye.mutiny.Uni<String> graphExplain(K key,
                                            String query)

Execute the command GRAPH.EXPLAIN. Summary: Constructs a query execution plan but does not run it. Inspect this execution plan to better understand how your query will get executed. Group: graph

Parameters:

key - the key, must not be null

query - the query, must not be null

Returns:

a uni producing the string representation of the query execution plan

graphList

io.smallrye.mutiny.Uni<List<K>> graphList()

Execute the command GRAPH.LIST. Summary: Lists all graph keys in the keyspace. Group: graph

Returns:

a uni producing the list of list of keys storing graphs

graphQuery

io.smallrye.mutiny.Uni<List<Map<String,GraphQueryResponseItem>>> graphQuery(K key,
                                                                                  String query)

Execute the command GRAPH.QUERY. Summary: Executes the given query against a specified graph. Group: graph

Parameters:

key - the key, must not be null

query - the query, must not be null

Returns:

a map, potentially empty, containing the requested items to return. The map is empty if the query does not have a return clause. For each request item, a GraphQueryResponseItem is returned. It can represent a scalar item (GraphQueryResponseItem.ScalarItem), a node (GraphQueryResponseItem.NodeItem, or a relation (GraphQueryResponseItem.RelationItem).

graphQuery

io.smallrye.mutiny.Uni<List<Map<String,GraphQueryResponseItem>>> graphQuery(K key,
                                                                                  String query,
                                                                                  Duration timeout)

Execute the command GRAPH.QUERY. Summary: Executes the given query against a specified graph. Group: graph

Parameters:

key - the key, must not be null

query - the query, must not be null

timeout - a timeout, must not be null

Returns:

a map, potentially empty, containing the requested items to return. The map is empty if the query does not have a return clause. For each request item, a GraphQueryResponseItem is returned. It can represent a scalar item (GraphQueryResponseItem.ScalarItem), a node (GraphQueryResponseItem.NodeItem, or a relation (GraphQueryResponseItem.RelationItem).
