Load Data Queries

Loading data into Memgraph is a challenging task. We have to implement something equivalent to the Neo4j LOAD CSV. This feature seems relatively straightforward to implement because LoadCSV could be another operator that would yield row by row. By having the operator, the operation would be composable with the rest of the CREATE|MERGE queries. The composability is the key because users would be able to combine various clauses to import data.

A more general concept is SingleStore Pipelines.

We already tried with Graph Streams. An option is to migrate that code as a standalone product here.
