Oracle Database 12.2 and 18.3 releases have introduced a number of extremely useful new indexing features and enhancements. These include cool capabilities such as automatically tracking index usage, advanced index compression enhancements, deferred invalidation of cursors during index creation/rebuild, automatic index maintenance during new online operations (such as online table moves and conversion to partitioned objects), JSON indexing enhancements, Memoptimized Rowstore and Scalable Sequences. There might even be an Oracle Database 19c surprise.
These will all be discussed in detail with practical examples on how they can be usefully deployed to improve overall database performance.
