How would such implementation look for SQL and array?

It cannot be used with PHP arrays unless you are working from an external source.
Thinking about SQL, it can only be used for larger datasets.

without partitions:

SELECT * FROM ... WHERE larege_text like `%apple%` order by created_at LIMIT 3
// after 5 mins
// result: 1, 2, 1000000001

with date partitions:

SELECT * FROM ... WHERE larege_text like '%apple%' and date <= '2019-01-01' order by created_at LIMIT 3
// result: 1, 2
SELECT * FROM ... WHERE larege_text like '%apple%' and date <= '2019-01-01' and id > 2 order by created_at LIMIT 3
// result: -
SELECT * FROM ... WHERE larege_text like '%apple%' and date >= '2019-01-02' and date < '2019-01-03' order by created_at LIMIT 3
// result: -
...
SELECT * FROM ... WHERE larege_text like '%apple%' and date >= '2019-02-01' and date < '2019-02-02' order by created_at LIMIT 3
// result: 1000000001

This is only useful for scanner-based databases / data sources. Closable, thoughtful does not make sense in the framework.
