SQL Anywhere 8.0

Adaptive Server Anywhere• Major enhancements to query execution engine and

optimizer• Storage improvements• Comprehensive data encryption• Improved administration and troubleshooting tools

Benefits:• Performance, performance, performance!• Improved security and usability• Stronger base for future enhancements

ASA 8.0 Performance Features

New query execution model• Additional join methods: sort-merge, hybrid-hash, block-nested

loop join (in addition to nested loop)

• More efficient disk-based sorting algorithm

• New grouping methods: hash, sort, index

• User-defined function caching

• More efficient subquery caching

Provides a solid base for future enhancements such as:• INTERSECT, EXCEPT set operators

• RECURSIVE UNION (bill-of-materials)

• OLAP operators


Enhanced optimizer• Chooses amongst suite of physical operators• Cost-based index selection• Significantly improved predicate analysis• Histograms used for selectivity estimation

• Data distribution evaluated during query processing; histograms are built and maintained automatically

• Data retained across unload/reload• Improved estimates for range predicates, DISTINCT/Group-by

cardinality• DBHIST utility for viewing histogram data

• New cost model validated for 8.0 query processing• Visual access plan displayer

Visual Access Plan Displayer Demo


Dynamic cache sizing on most platforms• Windows NT, 2000, XP, 95, 98, ME• All Unix platforms• Not CE, Netware

Improved SMP support - better scalability• New cache page replacement algorithm reduced

contention• New memory manager based on “Hoard” algorithm

reduced contention and fragmentation

ASA 8.0 New Features

Improved Cursor Support• Cleaner semantics (more closely match ANSI

and ODBC)

• True implementation of keyset-driven cursors

• Take advantage of new query optimization capabilities (eg. pre-fetch)

Support for FULL OUTER JOIN

ASA 8.0 New Features

Store enhancements: • New Patricia trie indexes

• Huge improvements for large key handling

• Appropriate index automatically chosen

• Improved file organization

• Large block I/O, table page bit-maps for improved sequential scan performance

• Checkpoint log moved to end of file reduces database file fragmentation and improves performance

• Table or index reorganization on-the-fly

• REORGANIZE TABLE and INDEX commands


Other Performance Improvements• Improved client/server buffer size negotiation• Fast database validation• Backup with log renaming now allowed with outstanding

transactions• Communication compression
