-------------------------------------

Sqoop's incremental import sounds suspiciosly similar: https://sqoop.apache.org/docs/1.4.2/SqoopUserGuide.html#_incremental_imports

> The idea is to allow migrating data from SQL stores to NoSQL stores or HDFS for archiving
purposes.
> This source will get a statement to execute and a scheduling policy. It will be able
to fetch timestamped data by performing range queries on a configurable field (this can fetch
data with incremental id as well). For fault-tolerance, the last fetched value can be checkpointed
to a file.
> Dealing with large datasets can be done via the fetch_size parameter. (Ref: https://docs.oracle.com/cd/A87860_01/doc/java.817/a83724/resltse5.htm)
