Specified by:

build in class io.grpc.stub.AbstractStub<DMLGrpc.DMLStub>

insert

public void insert(CottontailGrpc.InsertMessage request,
 io.grpc.stub.StreamObserver<CottontailGrpc.QueryResponseMessage> responseObserver)

 Inserts data into an entity. Each INSERT returns a record with a status. 
 

insertBatch

public void insertBatch(CottontailGrpc.BatchInsertMessage request,
 io.grpc.stub.StreamObserver<CottontailGrpc.QueryResponseMessage> responseObserver)

 Inserts data into an entity in batches! InsertMessages are collected until Cottontail DBs cache is saturated and then persisted in one go. 
 

update

public void update(CottontailGrpc.UpdateMessage request,
 io.grpc.stub.StreamObserver<CottontailGrpc.QueryResponseMessage> responseObserver)

 Updates data in an entity. Each UPDATE returns a record with a status. 
 

delete

public void delete(CottontailGrpc.DeleteMessage request,
 io.grpc.stub.StreamObserver<CottontailGrpc.QueryResponseMessage> responseObserver)

 Deletes data from an entity. Each DELETE returns a record with a status.
