Cassandra source statement vs copy
Copy is usually used for smaller amounts of data. The recommended approach is to use SSTable Loader and create SSTable files from your data. This is a bit more work, but should result in quicker ingestion. You could also try using Spark and ingest into Cassandra via Spark. As for inconsistencies, Cassandra does upserts based on primary keys. If more than one row matches the same primary key, the

neo4j: LOAD CSV doubled first data record of the CSV
I tried this and ended up with 3 Users, 3 Groups and the relationships connecting them exactly as you'd expect: load csv from "https://gist.githubusercontent.com/mneedham/256b809f5622aebc311f/raw/0be2d9fac59ee453314c140f778c25b8fcad4b4c/file.csv" as csvLine MERGE (u:User { name: csvLine[0]}) MERGE (g:Group { name: csvLine[1]}) CREATE (u)-[:IS_MEMBER_OF]->(g) Can you show the output of doing

neo4j: Cypher LOAD CSV with uuid

For your second question, I think

Single Char is treated as Two Char
I suppose that GENDER is VARCHAR2(N), where N is a max length in bytes (by default). In this case you can alter your column type: GENDER VARCHAR2(N CHAR) to give the maximum length in characters instead of bytes. Or you simply have a small N (the max allowed value is 4000 for table column size)
