MySQL Fabric 1.5.2
36

http://www.mysql.com/products/enterprise/fabric.html
MySQL Fabric
MySQL Fabric es un framework extensible & fácil de utilizar, para administrar ambientes
de clustering con MySQL. El framework implementa 3 funcionalidades: Tolerancia a
Fallas, Distribución de carga Sharding, & aprovisionamiento de entornos de manera
automática.
MySQL Fabric, gestiona también grupos de servidores con MySQL Replication y permite
un failover automático gestionado por el nodo MySQL Fabric Controller en combinación
a los Drivers Fabric-Aware: Java, PHP, Python & .NET y próximamente Lenguaje C.
El Fabric connector, puede en rutar transacciones en base a un criterio definido por el
desarrollador, permitiendo también escalar de manera horizontal en activo - activo en
múltiples grupos de data shards.
Por otro lado, la extensión Sharding de MySQL Fabric, permite que el desarrollador pueda
distribuir bases de datos, sobre un conjunto de servidores físicos gestionados por MySQL
Fabric, esto con el fin de poder escalar elásticamente agregando o reduciendo el número
de nodos en el grupo de servidores.
37

Java, PHP, .NET, C (labs)
– Lower latency, bottleneck-free

MySQL Replication & MySQL Fabric HA
• MySQL Replication is the initial implementation used in HA Groups
– PRIMARY = Replication Master & receives all writes
– SECONDARY = Replication Slave & receives share of reads
• Failover
– MySQL Fabric detects failure of PRIMARY/Master
– Selects a SECONDARY/Slave and promotes it
– Updates State Store
– Updated state fetched by Fabric-aware connectors
How this effects failover
40

High-Availability Group Concept
• Abstract Concept
– Set of servers
– Server attributes
• Connector Attributes
– Connection information
– Mode: read-only, read-write, ...
–Weight: distribute load
• Management Attributes
– State: state/role of the server
State: Primary
Mode: Read-Write
Host: server-1.example.com
41

Create HA Groups and add Servers
• Definiendo el grupo
mysqlfabric group create my_group
• Agregando servidores al grupo
mysqlfabric group add my_group server1.example.com
mysqlfabric group add my_group server2.example.com
42

Create HA Groups and add Servers
• Promoviendo un servidor a Primario Master
mysqlfabric group promote my_group
• Activación del FailOver detector
mysqlfabric group activate my_group

MySQL Fabric ( Sharding )
45

Benefits of Sharding
• Write scalability
– Can handle more writes
• Large data set
– Database too large
– Does not fit on single server
• Improved performance
– Smaller index size
– Smaller working set
– Improve performance (reads and
writes)
UID 10000-20000 UID 20001-40000
46

MySQL Fabric Sharding & Provisioning Features
• Connector API Extensions
– Support Transactions
– Support full SQL
• Decision logic in connector
– Reducing network load
• Shard Multiple Tables
– Using same key
• Global Updates
–Global tables
– Schema updates
• Sharding Functions
– Range ( Integer, String, datetime )
– Hash (Consistent)
• Shard Operations
– Shard move
– Shard split
• Server Provisioning
– Integrated with OpenStack & other
frameworks

MySQL Fabric: Sharding Setup
• Set up some groups
– my_global – for global updates
– my_group.N – for the shards
– Add servers to the groups
• Create a shard mapping
– A “distributed database”
– Mapping keys to shards
– Give information on what tables are sharded
• Add shards
51

MySQL Fabric:
Moving and Splitting Shards
• Moving a shard (id=5) from existing group to another (my_group.8)
mysqlfabric sharding move 5 my_group.8
• Splitting a shard (id=5) into two parts with new half stored in group
my_group.6
mysqlfabric sharding split 5 my_group.6
52

Connector API: Shard Specific Query
• Indicate tables to be used in query
– Property: tables
– Fabric will compute map
• Indicate read-only queries
– Property: mode
• Provide sharding key
– Property: key
– Fabric will compute shard
• Joins within the shard (or with
global tables) supported
conn.set_property(tables=["test.subscribers"], key=sub_no, mode=fabric.MODE_READONLY)
cur = conn.cursor()
cur.execute(
"SELECT first_name, last_name FROM subscribers WHERE sub_no = %s", (sub_no)
)
for row in cur:
print row
53

Connector API: Global Update
• Set global scope
– Property: scope
– Query goes to global group
conn.set_property(tables=[], scope='GLOBAL')
cur = conn.cursor()
cur.execute("ALTER TABLE test.subscribers ADD nickname VARCHAR(64)")

• Fabric creates new machines,
& MySQL Servers
– Initially using OpenStack Nova
– Other frameworks on the way
(OpenStack Trove, AWS,…)
• Server setup
– Clones slave
– Sets up replication
– Performs custom operations
55
Server Provisioning – OpenStack Nova Integration

MySQL Fabric executor
• Event driven
– Events will trigger execution of
procedures
– Procedures can trigger events themselves
– Each step of a procedure is called a job
• Procedures
– Written in Python
– Interacts with servers
– Write state changes into backing store
– Lock manager for conflict resolution
• Conservative two-phase locking strategy
• Avoid deadlocks
Backing
Store
Queue
Events

Example of User-Defined Executor Script:
Automatically replacing a server in a group on failure
• Register procedure for event
– @on_event decorator
– Accept event to register for
• Fetch the group the server
belonged to
• Fetch a new server from the
provider
• Add the server to the group
@on_event(SERVER_LOST)
def _add_server(group_id, server_uuid):
group = Group.fetch(group_id)
machines = PROVIDER.create_machines(
parameters
)
server = MySQLServer( server_uuid,
address
)
MySQLServer.add(server)
group.add(server)

MySQL Fabric: Goals & Features
• Connector API Extensions
– Support Transactions
– Support full SQL
• Fabric-Aware Connectors at GA:
– PHP + Doctrine, Python, Java + Hibernate,
.NET, C (pre-GA)
• Decision logic in connector
– Reducing latency &network load
• Load Balancing
– Read-Write Split
– Distribute transactions
• Global Updates
– Global data
– Schema updates
• Sharding Functions
– Range
– (Consistent) Hash
• Shard Operations
– Shard move
– Shard split
• Server Provisioning
– OpenStack Integration (& other
frameworks)
59

MySQL Fabric – Current Limitations
• Routing is dependent on Fabric-aware
connectors
– Currently Java (+ Hibernate), PHP (+
Doctrine), Python, .NET & C (labs)
• MySQL Fabric node is a single (non-redundant
process)
– HA Maintained as connectors continue to
route using local caches
• Establishes asynchronous replication
– Manual steps to switch to semisynchronous
• Sharding not completely transparent
to application (must provide shard
key – column from application
schema)
• No cross-shard joins or other queries
• Management is through CLI, MySQL
protocol or XML/RPC API
– No GUI
