Sergey Chugunov updated IGNITE-16697:
-------------------------------------
Epic Link: IGNITE-16923
> [Versioned Storage] POC - add methods for versioned data storage
> ----------------------------------------------------------------
>
> Key: IGNITE-16697
> URL: https://issues.apache.org/jira/browse/IGNITE-16697
> Project: Ignite
> Issue Type: Improvement
> Reporter: Ivan Bessonov
> Assignee: Ivan Bessonov
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-alpha5
>
> Time Spent: 10h 20m
> Remaining Estimate: 0h
>
> As a first step towards MV-storage in Ignite 3.0 it's required to have
> specific methods on the partition storage and index storage interfaces. These
> will replace currently available VersionedRowStore, which was a prototype in
> itself and doesn't correspond to a desired functionality.
> Partition storage needs:
> * addWrite(k, v, txId)
> * commitWrite(k, ts)
> * abortWrite(k)
> * read(k, ts)
> * scan(ts, {_}tbd{_})
> * cleanup({_}tbd{_})
> Sorted index storage needs:
> * scan(lower, upper, bounds_options, projection, partition_filter, ts)
> Index updates will be hidden inside of {*}addWrite{*}, *abortWrite* and
> *cleanup* methods. No external "update" and "remove" are required.
> This particular issue is a precursor for the
> https://issues.apache.org/jira/browse/IGNITE-16611.
> Reference implementation is also required, it'll provide an example of what's
> expected from the storage and a set of tests to fix methods contracts.
