Support Matrix for Python / Elastic Stack version

The column for "Supported in Next Major" is subject to change until feature freeze of the next major depending on usage.

Process

Currently we support Python 2.7, and 3.4 onwards as of Elasticsearch v7.x.
Python versions will come out every year however the amount of changes between 3.x to 3.[x + 1] are much smaller than 2 to 3.

Here's the query being used to determine what Python versions should be supported in 8.x by looking at the split of downloads for 7.x:

SELECT SUBSTR(details.implementation.version, 1, 3) AS ver, COUNT(*) as dwn FROM `the-psf.pypi.file_downloads` WHERE DATE(timestamp) = "2021-04-22" AND file.project = 'elasticsearch' AND file.version = '7.12.0' AND # Filter out PyPy versions SUBSTR(details.implementation.version, 1, 1) <= '3' AND ( # Filter out Python 2.6 or earlier SUBSTR(details.implementation.version, 1, 1) != '2' OR SUBSTR(details.implementation.version, 1, 3) = '2.7' ) AND ( # Filter out Python 3.3 or earlier SUBSTR(details.implementation.version, 1, 1) != '3' OR SUBSTR(details.implementation.version, 3, 3) >= '4' ) GROUP BY ver ORDER BY dwn DESC 

JSON results from Google BigQuery fed into this little script to quickly recalculate:

x = {tuple([int(p) for p in d["ver"].split(".")]): int(d["dwn"]) for d in x} total = sum(x.values()) x['3.7+'] = sum([v for k, v in x.items() if k >= (3, 7)]) x['3.x+'] = sum([v for k, v in x.items() if isinstance(k, tuple) and k >= (3,)]) for k in list(x.keys()): if isinstance(k, tuple) and k >= (3, 7): x.pop(k) for k, v in x.items(): print(k, f"{v * 100.0 / total:.2f}%")
