Implement datetime range filters

[stevedodson]

eland.DataFrame and eland.Series, don't currently support datetime range filters. E.g.

f = '%Y-%m-%dT%H:%M:%S'

start = datetime.datetime.strptime('2020-08-14T00:00:00', f)
end = datetime.datetime.strptime('2020-08-14T01:00:00', f)

ed_df[(ed_df['@timestamp']>=start) & (ed_df['@timestamp']<end)]

throws

Any news on this? I see that it is part of the next milestone but is still at 0%. Is the project dead?

@MyronM95 Thanks for your concern. The project isn't dead, it's in heavy use within and outside of Elastic. We're in the process of finding a new shepard for Eland's development as I currently don't have enough time to contribute the same way I was months ago. Your patience is appreciated and you're welcome to try contributing if a particular feature is very important to you.
