11. Alfresco reaches the 1B document mark on AWS
• 10 Alfresco 5.1 nodes, 20 Solr 4 nodes in Sharding mode, 1 Aurora DB
• Loaded 1B documents at 1000 docs / sec – 86M per day
• Indexed 1B documents in 5 days – > 2000 docs / sec
• No degradation in ingestion or content access upon content growth
• Tested up to 500 Share concurrent users and 200 CMIS concurrent sessions
Highlights
“We applaud Alfresco’s ability to leverage Amazon Aurora to
address business requirements of the modern digital enterprise,
and enable a more agile and cost-effective content
deployments.”
Anurag Gupta, Vice President, Database Services, Amazon Web Services, Inc. –
2015 October 6th
Press release

12. Introducing the 1B documents benchmark
• Repository Layout
– 10k sites; 2 levels deep; 10 folders per level; 1000 files per folder
– 100 kb avg plain text files with varying content complexity (for indexing purpose)
– Default content model
• Scenarios
– Share interaction (Enterprise Collaboration)
• First focused on the Repository, no Search
• Then with Search, including Solr 4 Sharding
– CMIS interaction (Headless Content Platform)
• Transactional Metadata Query testing
• Fully cloud environment (provisioned by chef-alfresco)
– Alfresco 5.1 + Share 5.1 (head code, unreleased)
– AWS EC2 / Aurora (Mysql compatible and Alfresco supported)
– Ephemeral for Index storage / EBS for content storage (spoofed)

15. Getting to 1B documents
• Ingestion
– With 10 nodes, 1000 documents / second (3 million per hour, 86M per day, 12
days) – spoofed content comparable to an in place BFSIT loading
– Load rate consistent even beyond 1B documents
– Throughput grew linearly by adding ingestion nodes (100 docs / sec per node)
– Adding additional loading nodes likely to raise ingestion throughput – as
Aurora was only at 50% CPU
• Indexing
– Index distributed over 20 Solr shards, sharding on ACLs optimized for site
based repository, with Alfresco tracking node
– Each shard holds approx (in excess of) 50M nodes
– Re-Indexing completed in about 5 days (each node tracks a sub-set of the 1B)
– Dynamic sharding autoconfiguration (5.1 feature)
NOTE: requires Alfresco tracking nodes to be in the cluster
BenchmarkResults

16. The following information is based on a development version of the unreleased Alfresco 5.1.
Performance data is provisional and subtle to change based on testing the final Alfresco 5.1 release.

17. Testing Alfresco on 1b docs
• Repository Only (500 Share users) test
– Sub-second login times and good, linear responses for other actions
• Open Library: 4.5s / Page Results: 1s / Navigate to Site: 2.3
– CPU loads:
• Database: 8-10% / Alfresco (each of 10 nodes): 25-30%
• Shows room for growth up to 1000 concurrent users
• Repository + Search (100 Share users)
– Metadata and full text search ~ 5s (on 1B documents)
– 1.2 searches / sec hitting the 20 shards
• TMDQ queries (database only, no index) via CMIS
– IN_FOLDER (sorted, limited) ~ 160ms at CMIS interface
– CMIS:NAME (=, LIKE) ~ 20ms at CMIS interface
BechmarkResults

18. Lessons Learned
• A single Alfresco repository can grow to 1B documents on AWS without
notable issues, especially with a scalable DB like AWS Aurora
• As for the index, Shard, Shard, Shard
– Shard to cope with content growth
• Single Solr instance tuned for 50M docs / 32GB
– Shard for performance / SLA
• Improve performance of search on large scale repositories to hit SLA requirements
– Shard for operational reasons
• Improve reindexing time (1B docs re-index in 5 days with 20 shards)
NOTE: Sharding has a cost of results post-ranking. Use reasonably.
• No indications of any size-related bottlenecks with 1.1 Billion Documents
• DB Indexes optimized (no index scans) even at a 3.2TB Aurora DB
Recommendations

19. Key Alfresco 5.1 scalability items to look forward to
• Alfresco Solr Sharding
– On ACL
– Tested up to 80M documents per shard and 20 shards
• Improved Transactional metadata queries
– Boolean, Double and OR construct
• Easy deployment and scaling in AWS using provisioning technologies like
chef-alfresco
• Alfresco support for Amazon Aurora (also available in Alfresco 5.0)
• Updated field collaterals

21. Upgrade Task Force
1. In place application of SP & HF (not major and minor upgrades, for now)
2. Separation of Share and Platform releases for independent consumption
(and definition of a clear compatibility matrix)
3. Consolidation of Public API Lifecycle to ensure high longevity
customizations (no need for re-test)
Enabling a seamless maintenance for Alfresco
NOTE: Not tied to Alfresco 5.1, the update assistant will be released for earlier versions

22. Effects to the product lifecycle
Share / Platform separation
Platform and
Share can be built
and developed
independently
Dev
Release
Install
Platform and
Share
can be released
independently (or
together)
Maintain
Suite and
independent
installers for
Alfresco and
Share
Consume new
version of
Platform & Share
independently

23. Modularizing the platform
Breaking the monolith
Alfresco Platform
Core set of functionalities exposing
extension points including Java and
ReST APIs
Transformation services
Can be scaled independently using
the transformation server or in MM for
video transformations
Share services (New!)
Subset of platform functionalities now
extracted in a separate module (AMP)
following the Share release lifecycle
Search services
Can be scaled independently as it relies
on Solr4 standalone (with Replication and
Sharding support)

24. Share separation takeaways
1. Share (only) releases will now contain a share-services.amp which contains
Share specific backing APIs
2. Platform (only) released will no longer contain Share specific Java services
3. All-in-one installers (Share + Alfresco + AMPs) will be produced
4. Compatibility between Share & Alfresco is driven by the Java (not ReST)
APIs compatibility policy (wait for it…in the next slides!)
5. Expect more frequent Share releases on prem (quarterly) and on cloud
What you need to know!

28. Developer platform consolidation
1. Documentation of supported Platform, Share and ReST extension points
Move old ReST API to Limited Support
Invest on the new Alfresco ReST API V1
Cleary identify and document supported Java and Share extension points
2. API lifecycle, support and Backward compatibility
In process - Major version support
ReST - Independently versioned and inherently backward compatible
3. Customer success driven tactical investments on the Java platform & modules
JAR simple module support (for Alfresco and Share)
Physical isolation of modules without need to modify Alfresco (immutable)
Share modules support and reporting
Ongoing activities targeting Alfresco.next

How can you help

30. It’s not just about the docs
Tutorials
Key extension / integration points have extensive tutorials – Kudos @Martin!
Samples
Both Share and Alfresco side, all samples consolidated on alfresco-sdk-samples
Sample code runs as backward compatibility test at every build as one more layer of Backward Comp
A consolidated library of what’s possible, anything not in here à not supported
Support Status
Each API set level will have clear support status defined (Full Support, Limited Support, KB Support)
At single API level we will also have support status, to signal our investements (e.g. old “surf” extension
points)
Work with support will undergo over the next months to update Support Handbook
NOTE: This is a live list. We will have a process to introduce new extension points where valid request
Nobody really loves to RTFM

31. So what about compatibility?
1. Major version for Platform and Share extensions (modules)
Your custom module built on 5.1 Public API will work throughout the whole 5.x
Alfresco modules can be compatible for a major version
2. ReST API version driven support for integrations (standalone apps)
Not bound to the Alfresco version
Clear rules for versioning of ReST APIs
Supported until v+2 is released or 1y after v+1 is released (the earliest)
For internal and external Alfresco extensions and integrations

32. Alfresco SDK
What’s out already
Alfresco SDK 2.1.0 - Compatible with 5.0, with hot reloading (Platform &
Share)
Alfresco SDK 2.1.1 - Multiple bug-fixes, backward compatible
Together with Alfresco next
Fully supported, easily forkable and complete set of samples on alfresco-
sdk-samples (in Github)
Improved hot reloading
Customer value driven prioritization of Public Github issues. Request
enhancements at https://github.com/Alfresco/alfresco-sdk/issues
Making Alfresco development even more productive, safe and fun

33. What & when?
