Summary: [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
Fix For: 3.0.0-alpha5
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.
