[jira] [Updated] (IGNITE-21987) Optimize RO scan in sorted indexes
[ https://issues.apache.org/jira/browse/IGNITE-21987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ivan Bessonov updated IGNITE-21987: --- Description: 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.
