Highly Available Ops Manager Architecture
In this scenario, a highly
available Ops Manager
requires 8 physical servers,
not including the HTTP load
balancer.
Apart from the HTTP
Services, the solution requires
3 MongoDB replica sets of 3
data nodes each;
One each for the Application
Database, and the Backup
Blockstore Databases #1 &
#2.

ClusterControl uses a single MySQL /
MariaDB database server, to which
its core services connect to store and
retrieve data.
Redundancy can be achieved
through deploying a database
snapshot on a second node, and
installing the ClusterControl
applications.
With a HTTP proxy in front, requests
can be directed to the live node.
ClusterControl services such as
auto-recovery should be stopped on
the second node to avoid
complications.

○ LDAP Authentication
● New Storage Engines
○ Percona Memory Engine (compatible with Memory Engine in MongoDB EE)
○ MongoRocks is integrated
● Native Hot Backup Capability
○ Supports both MongoRocks and Wired Tiger storage engines
● Integration with Percona Toolkit and Percona Monitoring and Management (PMM)
for query performance analytics and troubleshooting
● Enhanced Query Profiling

● Added to Percona Server for MongoDB in partnership with Facebook
● Based on the open-source RocksDB library derived from LevelDB
● Uses LSM-trees instead of B-trees for indexes, optimizes for write-heavy
workloads
● Has native support for Snappy, LZ4, and Zlib compression
● LSM-Trees are append-only, so are fast regardless of disk size or available
space.
● Writes go to Memtables first before being flushed to disk, reads are
serviced from memory if possible
● Compared to Wired Tiger, MongoRocks uses less disk space, maintains
higher insert rates, and has better response times.

● QAN for MongoDB was announced at Percona Live Europe in Dublin,
September 2017
● Query Profiling in the upstream implementation can incur significant
performance overhead
● Percona Server for MongoDB implements an optimized query profiler that
supports setting rate limits
● For example to profile all operations only for queries which are slower
than 200ms and every 100th fast query, you would do the following:
○ mongod --profile 2 --slowms 200 --rateLimit 100
● Integrates with Percona Toolkit using pt-mongodb-query-digest tool
