Building and maintaining indexes

Indexes provide operational ease for populating and maintaining the index.

An advantage of indexes is the operational ease of populating and maintaining the index. Indexes are built in the background automatically, without blocking reads or writes. Client-maintained tables as indexes must be created manually; for example, if the rank column had been indexed by creating a table such as rank_idx_table, your client application would have to populate the table with data from the rank_by_year_and_name table.

To perform a hot rebuild of an index, use the nodetool rebuild_index command.
