• Durability Options
• Storage Enhancements
• Improved Performance
• Planner Improvements
• Miscellaneous Features
• Shadow (Re)Indexer

5. What is Query Fanout?
When ClustrixDB executes a query, it is split into fragments for
execution. These fragments are then passed to the various CPUs for
execution. Depending on the query type and complexity, each
fragment can have multiple stages of execution.
Query Fanout is the process by which fragments of a query are run
simultaneously on multiple CPUs per node. This allows for expanded
parallelism and much shorter execution times.

6. Improved Query Fanout
• Fanout multiple cores per node per
phase of query execution
– Even better distribution of workloads
– Increased query parallelism for faster
execution times
• Improved Fanout for DDL
– ALTERS up to 400% faster
– Adding Indexes and columns
– Re-slicing tables
• Improved Row Based Replication speed
– Up to 45% increase in performance
6

7. What are Durability Options?
ClustrixDB now has optional levels that allows the user to determine
at which point in the commit process the application is notified of a
successful commit.
7

8. Durability Options(1 of 2)
• Optional early commit reporting for lower latency and higher
throughput
• Three possible settings to tune durability vs performance
• All transactions ultimately durable
– Default Commit Reporting is full ACID
– All Commit Reporting modes use the same commit process
• Session or Global Variable
– Allows for critical workloads to remain fully ACID and lower value
workloads to be near-ACID.

9. Early Durability Reporting(2 of 2)

10. Storage Enhancements
• New guardrails and warnings
– Prevent the database from becoming completely full
– Alert at multiple levels due to severity of disk usage
10
• Pre-allocate storage
– device1 (database storage) pre-
allocated at cluster formation
– Configurable via ALTER command
• Pre-allocate temp space
– device1-temp (temp space) pre-
allocated at database start
– Configurable via global variable

11. Improved Performance (page 1 of 2)
• Increased near linear
scale to 30 nodes
• 10x concurrency boost
(number of connections
per node)
• Query Fanout processing
now default behavior (all
previously mentioned
goodies come standard)
11

12. Improved Performance (page 2 of 2)
• Default distribution for representations now based on first column of
an index.
– Reduction in broadcasting and latency
– Reduced query plan cost
– Shorter query runtimes
• Performance improved for INSERT INTO... SELECT FROM... ON
DUPLICATE KEY statements that encounter duplicates
• Improved performance on workloads with heavy use of temporary
tables
• Performance improved for count(*)
12

13. Planner Improvements
• Improved planning on tables with indexes
• Specific performance improvements
– Queries using ISNOTNULL
– Cardinality estimation after
LIMIT/OFFSET
– Queries having multiple IN predicates
with OR
• Optimized planner memory management
13

14. Other Features in ClustrixDB v7.5
• Improved clx administration tool
– Massively improved operation speed
– Better error reporting
• Improved Installation Process
– Better Guardrails
– Easier Setup
• Fast Backup/Restore
– Added database.table EXCLUDE functionality
14

15. Introducing the Shadow (re)Indexer
Re-write of two modules of the Magento Platform
• Clustrix EAV
– Dramatically improves data store retrieval from primary data tables
– Removes need for flat tables
• Reindex faster and less often
• Clustrix Indexer
– Tunes indexes to run better on Clustrix
– Improves processing behavior
15

16. What is the Clustrix Shadow (re)Indexer?
• Rewrite of the Magento Indexer and Magento EAV Systems
– Optimized to address common problems on the Magento platform
experienced by high-transaction sites
• Removes frustrations and downtime stemming from catalog updates
– Update catalog and index anytime
– Catalog updates appear in your store in seconds
– Avoid major site slow-downs due to indexing
– No major downtime or check-out issues
• No impact on site performance
– Users are able to browse and shop on the site
16

17. ClustrixGUI Preview
• ClustrixDB 7.5 includes a beta of the
newly redesigned browser-based user
interface, ClustrixGUI. The new UI is
organized to give the user quick
insight into the overall performance of
key metrics.
• The health dashboard provides insight
into transactions per second, CPU
utilization, storage usage, and latency
for both reads and writes.
• With this dashboard it is simple to get
an “at a glance” overview of your
clusters current and recent health.

The Health dashboard in ClustrixDB 7.5 provides a visual summary of your
database cluster. Quickly review key performance metrics.

18. Comparison
18
● In the Compare tab you can
easily identify bottlenecks
and performance issues.
● The comparison tool provides
the ability to select two points
on a graph and quickly see
the queries that were running
at those times.
● Extremely useful tool to
identify problem queries that
may be the cause of a
performance slow-down or
CPU spike.

19. Graphing
19
● The ClustrixGUI Graphs page
provides a multitude of graphs for
deep insight into the historical
workings of the cluster.
● Completely reworked from the
ground up to give a more intuitive
graphing experience.
● Can now mark points in time with a
picker needle to easily compare
spikes and dips over multiple
graphs.

20. Flex Up and Flex Down
● No more typing of difficult to
remember and complicated IP
addresses.
● Easily scan your network for
available node.
● Simply scan, click, scale.
