What is new in Enterprise 10.1 ?

Security enhancements will be presented in our next webinars.

Galera is now inside

MariaDB Enterprise 10.1

■ The MariaDB Server and MariaDB

Galera Server packages have been

combined

■ Galera packages and their

dependencies get installed

automatically

■ The Galera parts remain dormant

until configured, like a plugin or

storage engine

Enterprise support services for the Galera

Cluster functionality is included in our

MariaDB Enterprise Cluster subscription.

Two new Information Schema tables

for examining wsrep information,

WSREP_MEMBERSHIP and WSREP_STATUS

have been added.

MariaDB Enterprise Cluster adds node's

status and cluster membership related

information to the

INFORMATION_SCHEMA.

This information can be used by monitoring

systems and also by MariaDB MaxScale.

High Availability

To : Try to replicate any transaction in

parallel, as long as a transaction can be

rolled back and re-tried (eg. InnoDB/XtraDB

DML).

■ If there are no conflicts, then great,

parallelism will be improved.

■ If there is a conflict, the enforced

commit order will cause it to be

detected as a deadlock, and the later

transaction will be rolled back and

retried.

More information on optimistic replication

Scalability EnhancementOptimistic parallel replication – all

transactions will be considered to be run in

parallel, giving another performance boost

in master-to-slave replication

Moving from : only run in parallel

transactions that were known to be able to

safely replicate in parallel.

Slave execution of triggers

when using row-based replication

MySQL's replication system can replicate trigger actions

automatically for statement-based replication

and row-based replication.

More information on triggers on slaves7

Scalability Enhancement

■ If you want to have a setup where a slave has triggers that are not present on the master

(ie. slave needs to update summary tables or perform some other ETL-like process),

■ If you uses statement-based replication, they can just create the required triggers on the

slave. The slave will run the statements from the binary log, which will cause the triggers to

be invoked,

■ If you use row-based replication and for example that the master is Galera cluster node.

you can use row-based events to invoke triggers on the slave.

But now in addition:

And many more improvements such as:

■ A mechanism to filter replication events on the slave replication server based on

domain_id. see CHANGE MASTER TO

■ Enhanced semisync replication; Wait for at least one slave to acknowledge transaction

before committing

■ Dump Thread Enhancements from Google to makes multiple slave setups faster by allowing

concurrent reading of binary log.

■ Commits in certain instances in parallel replication complete immediately, avoiding losing

throughput when many transactions need conflicting locks. See

binlog_commit_wait_count.

■ RESET_MASTER is extended with TO # which allows one to specify the number of the first

binary log.

■ 15 new Webscale patches included (and 9 were already there)

Scalability Enhancement

InnoDB/XtraDB Page Compression

■ Alternative to compress tables different (but similar) to the InnoDB COMPRESSED storage format

● InnoDB Compressed stores : both uncompressed and compressed pages in the buffer pool

● Page Compression, stores only uncompressed pages

■ Currently 6 algorithms are possible : ● zlib, lz4, lzo, lzma, bzip2, snappy

■ Possible on any file system● But most beneficial on SSDs and Non-Volatile

Memory

Performance - InnoDB

Optimizer enhancements including EXPLAIN JSON and EXPLAIN ANALYZE (with FORMAT=JSON)

■ ANALYZE statement provides output that looks like EXPLAIN output, but also is includes data from the query execution (how many rows were actually read, etc)

■ ANALYZE FORMAT=JSON produces detailed information about the statement execution

Many small optimizations to improve performance

■ From 16K to 64K pages in InnoDB ■ Facebook/Kakao defragmentation patch (Defragmenting InnoDB

Tablespaces)■ Query timeouts

10

Performance - InnoDB

MariaDB 10.1 is now fully compliant with the OGC standards around GIS.

■ Support for Spatial Reference systems for the GIS data

● new REF_SYSTEM_ID column attribute can be used to specify Spatial Reference System ID for columns of spatial data types

■ More functions from the OGC standard added :● ST_Boundary● ST_ConvexHull● ST_IsRing● ST_PointOnSurface● ST_Relate
