Does the IMDB support indexes like conventional RDBMS?
Yes, TimesTen supports indexes. Indexes improve the performance of queries to the database, just as they do in a RDBMS. TimesTen supports two types of indexes: Hash indexes, which are automatically created on the primary key of the table, and T-Tree indexes, which are created with the CREATE INDEX statement. T-Tree indexes are optimized for memory and provide superior performance to the B-Tree indexes provided in disk-optimized RDBMSs..
