Column stores (e.g., Redshift, Vertica, Snowflake). Compressed column-oriented formats (e.g., Parquet for Spark or ORC for Hive). Conventional row-oriented formats (e.g., PostgreSQL, MySQL or other relational databases). Compressed row-oriented formats (e.g., Avro for Kafka). In-memory...
For loading data, if you are using postgres, mysql or other rdbms, the fastest way to load is through the copy command. Write a python method with file and table as parameter. Now, you can use this method as method(file, table, args = defaults) every time you need to load some data...
