Philipp Shergalis reassigned IGNITE-21987: ------------------------------------------ Assignee: Philipp Shergalis > Optimize RO scan in sorted indexes > ---------------------------------- > > Key: IGNITE-21987 > URL: https://issues.apache.org/jira/browse/IGNITE-21987 > Project: Ignite > Issue Type: Improvement > Reporter: Ivan Bessonov > Assignee: Philipp Shergalis > Priority: Major > Labels: ignite-3 > > This issue applies to aimem/aipersist primarily. Optimization for rocksdb > might be done separately. > * add new method to SortedIndexStorage, like "readOnlyScan", that returns a > simple cursor > * in the implementation we should use alternative cursor implementation for > RO scans - it should delegate calls to B+Tree cursor > * reuse existing tests where possible > * call new method where necessary (PartitionReplicaListener#scanSortedIndex) > IMPORTANT: we should throw an exception if somebody scans an index and > IndexStorage#getNextRowIdToBuild is not null. It should be a new error, like > "IndexNotBuiltException" -- This message was sent by Atlassian Jira (v8.20.10#820010)
