"GridDB has two container types: Collections which can have any type of row key, and TimeSeries which always have a timestamp as the row key"
Reference: https://griddb.net/en/blog/data-modeling-with-griddb/ rowKey for the collection container could also be set as timestamp so why have 2 types of container?
What is the benefit of using TimeSeries container as opposed to using collection container with timestamp rowkey?
