Video traffic on the Internet is constantly growing; networked multimedia applications consume a predominant share of the available Internet bandwidth. A major technical breakthrough and enabler in multimedia systems research and of industrial networked multimedia services certainly was the HTTP Adaptive Streaming (HAS) technique. This resulted in the standardization of MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH) which, together with HTTP Live Streaming (HLS), is widely used for multimedia delivery in today’s networks. Existing challenges in multimedia systems research deal with the trade-off between (i) the ever-increasing content complexity, (ii) various requirements with respect to time (most importantly, latency), and (iii) quality of experience (QoE). Optimizing towards one aspect usually negatively impacts at least one of the other two aspects if not both. This situation sets the stage for our research work in the ATHENA Christian Doppler (CD) Laboratory (Adaptive Streaming over HTTP and Emerging Networked Multimedia Services; https://athena.itec.aau.at/), jointly funded by public sources and industry. In this talk, we will present selected novel approaches and research results of the first year of the ATHENA CD Lab’s operation. We will highlight HAS-related research on (i) multimedia content provisioning (machine learning for video encoding); (ii) multimedia content delivery (support of edge processing and virtualized network functions for video networking); (iii) multimedia content consumption and end-to-end aspects (player-triggered segment retransmissions to improve video playout quality); and (iv) novel QoE investigations (adaptive point cloud streaming). We will also put the work into the context of international multimedia systems research.

21. • NDB$EPOCH2 and
NDB$EPOCH2_TRANS introduced
• Detects conflicGng inserts/updates/
deletes/reads
• EnGre transacGons (and dependent
ones) rolled back
• Rolling back of transacGons that
read conflicted data
• Improved NDB ExcepGons table
format
– Non-PK columns, operaGon type,
transacGon id, before and aper values
• Online conflict role change

22. • Primary stores logical Gmestamp (GCI)
against updated row(s)
– Window for conflict opens
• GCI is replicated with updated row(s) to
Secondary
• The same GCI is replicated back
(reflected) from Secondary to Primary
aper it has been applied
– Closing window for conflict
• Primary checks every event originaGng
from the Secondary to check for conflicts

36. When to Consider MySQL Cluster
l UpGme requirements
l Cost per minute of downGme?
l Failure versus maintenance?
l Scalability demands
l Sharding for write scaling?
l Latency demands
l Cost of each millisecond?
l ApplicaGon agility
l Developer languages and frameworks?
l SQL and NoSQL?

37. General Usage Considerations
• MySQL Cluster is designed for
– Short transactions
– Single key reads and writes
– Many parallel transactions
• Utilize simple access patterns for high running transactions
– Use efficient scans and batching interfaces
– Push down joins yield huge performance improvements for JOIN operations
– MySQL Cluster 7.4 speeds up table scans
• Storage Engine is configurable for each table…InnoDB or NDB

Accessing Data: PK Lookups
• Single TransacGon
Coordinator (TC), no
addiGonal data
distribuGon handling
• First statement decides TC
• Keep transacGons short!

Accessing data: Unique Secondary Key Lookups
• Secondary keys
implemented as hidden/
system tables
• Hidden tables have new
secondary key as PK and
base table’s PK as value
• Data may reside on same
node or other node

Accessing data: Range Scans and Joins
• TC is chosen using round-
robin
• Data nodes return data
directly to API
• Flow:
– Choose data node
– Send request to all LDM
– Send data to API

41. SELECT SUM(population) FROM towns WHERE
country=“UK”;
SELECT SUM(population) FROM towns WHERE
town=“Boston”;
• ParGGon selected using hash on
specified ParGGon Key
– Primary Key by default
– User can override in table definiGon
• MySQL Server (or NDB API) will
a}empt to send transacGon to the
correct data node
– If all data for the transacGon are in the
same parGGon, less messaging ->
be}er scalability
• Aim to have all rows for high-
running queries in same parGGon

43. Faster Joins – Pushdown Joins
• AcGvated when ndb_join_pushdown is on (default)
• Rules for a join to be pushed down:
1. Joined columns use idenGcal types
2. No reference to BLOB or TEXT columns
3. No explicit lock
4. Child tables in the Join must be accessed using ref, eq_ref, or const
5. Tables not explicitly parGGoned by [LINEAR] HASH, LIST, or RANGE
6. Query execuGon plan doesn’t use mysqld’s internal ‘join buffer'
7. If root of join is of the eq_ref or const type, child tables must be joined by eq_ref
• Run ANALYZE TABLE <table_name> on each table once
• Use EXPLAIN to see what components are being pushed down:
– For example: Extra: Child of 'd' in pushed join@1

49. MySQL Cluster Hardware SelecGon
• Up to 64 x86_64 bit CPU threads (vCPUs)
– High frequency: enables faster processing of messages
• CalculaGng RAM per Data Node (in-memory database)
– Database Size * # Replicas * 1.25 / # data nodes
– 50GB database * 2 replicas * 1.25 / 2 data nodes = 64GB of RAM
– Non-indexed columns can be stored on disk, reduces RAM requirements
• 2 NICs and 2 PSUs
• Deep-dive into network best-pracGces in Reference Architecture Guide
• Use MaxNoOfExecutionThreads or ThreadConfig to configure how threads
should be allocated

60. MySQL Cluster Backups
• Backup of NDB tables
– Online – can have ongoing transacGons
– Consistent – only commi}ed data and changes
are backed up
• ndb_mgm -e "START BACKUP"
– Copy backup files from data nodes to safe
persistent locaGon
– Non-NDB tables must be backed up separately
– MySQL system tables are stored in MyISAM or
InnoDB
• You want to backup (for each MySQL
Server)
– mysql database/schema
– Triggers, rouGnes, events, ...
• Use mysqldump
– mysqldump mysql > mysql.sql
– mysqldump --no-data -A >
schemas.sql
– mysqldump --no-data --no-create-
info -R > routines.sql
• Copy my.cnf & config.ini files

62. Features to Use With CauGon
• Large BLOBs
• Disk based tables
• Enforced Foreign Keys
• Large range scans and joins
• Spli…ng a single MySQL Cluster over mulGple data centers
• AcGve-AcGve Geographic ReplicaGon
– Fine to use but best if conflicts can be avoided on the applicaGon side
