  10. 10. Sizing Area Collaboration Headless Content Platform Search Search is usually just a small portion of the operations percentage (around 10%) In most of the cases especially for very large repositories there wont be full text indexing/search. Permissions Permission control happens at Alfresco layer. User authority structure will be complex. With users belonging to many groups in average. Most of the times permission control is happening elsewhere. Authority structures will be in general fairly simple. Ingestion Ingestion rates are usually not important uploads are normally manually driven. Injection rates are usually very important. Dedicated layers/nodes may be needed. Repository Size Repository Sizes are usually of small (hundreds of thousands) or intermediate (millions) size. Repository sizes are usually quite big (tens of millions to billions). Customizatio n Level of customization will vary but in most cases will concentrate at the front end (Share). Customizations are usually important, typically on the repository side. Custom solution code may live external to Alfresco by using CMIS, public APIs, etc. Architecture Architecture options will be in general the standard ones provided by Alfresco (cluster, dedicated index/transformation layers, etc). Architecture options may vary considerably with more high scale and availability solutions being used: proxies, cluster and un-clustered layers, multi-repositories options of Alfresco repository, etc. Concurrency Concurrent users will possibly be many, with average and peak values important to be considered. Concurrent users will be in general few but think times will be much smaller than for collaboration Interfaces You may expect mostly the Share interface to be used, but also it will be very common SPP, CIFS, IMAP, WebDAV and other public interfaces (CMIS) for other interfaces (mobile). Most of the load should concentrate around public API (CMIS) and custom developed REST API (Webscripts). Batch Batch operations should mostly be around human interaction workflows and the standard Alfresco jobs. Batch operations will usually have a considerable importance, including content injection processes (bulk import), custom workflows and scheduled jobs. 10 ECMScenarios ECM is no one size fits all.
  11. 11. 11 BechmarkResults 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 Solr4 Sharding – CMIS interaction (Headless Content Platform) • Transactional Metadata Query testing • AWS Fully cloud environment (provisioned by chef-alfresco) – Alfresco 5.1 + Share 5.1 (development code, unreleased) – AWS EC2 / Aurora (Mysql compatible and Alfresco supported) – Ephemeral for Index storage / EBS for content storage (spoofed)

  14. 14. 14 BenchmarkResults Getting to 1B documents • Ingestion – With 10 nodes, 1000 documents / second (3 million per hour, 86M per day, 12 days for the full repo) – spoofed content comparable to 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 Alfresco Index Servers, sharding on ACLs (good for site based repository), with Alfresco dedicated tracking instance – 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
  15. 15. 1515 BechmarkResults 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
  16. 16. 16 1Bdocstests Repository – Performances at 1B docs 500 concurrent Share users – no search NOTE: Minor repo changes between 5.0.1 and 5.1 – performance are comparable 0 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 Arithmetic Mean (ms) Standard Deviation (ms) Avg response time (ms) Std deviation (ms)
  17. 17. 17 Recommendations 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 • Low
  18. 18. 18 FolderSizematters Limiting the number of files in a folder is a good best practice Avg response time (ms) – 1000 docs/folder Avg response time (ms) – 5000 docs/folder
  19. 19. 19 Outofscope 1B document Benchmark – Requires further testing • The following items were out of scope for the benchmark and will be tested in the future. Keep this into account when using this info for sizing. • Content Store I/O – File were spoofed, so not on the filesystem (bm-dataload allows to store them) – What does it mean from a scalability standpoint? • For ingestion, comparable to an in-place ingestion of content with BFSIT • For indexing, no difference, Alfresco provides Solr with on-the-fly generated content • For performance testing, difference in download, negligible with large files • Transformation server / subsystem • All files are plain text files • Can be added to testing at later stage, as it’s a separate dimension • Trying to keep the problem ‘testable’
  20. 20. 20 Conclusions Conclusions • Alfresco can power Enterprise Grade deployments of several ECM use cases in a fully AWS best-of-breed cloud environment • Alfresco Repository can ingest and serve 1B documents without bottlenecks or notable performance issues • The Alfresco Index Server, as of 5.1, will leverage sharding to support large distributed, high performance indices • Using Alfresco in conjunction with AWS Aurora is a powerful combination to reach high scalability without operational complexity • Alfresco is investing in provisioning technologies like chef-alfresco to ensure a seamless experience for DevOps deploying Enterprise Grade architectures in the cloud • This data is based on Alfresco: further testing is undergoing to provide additional data and provide Alfresco 5.1 final sizing & scalability guidelines
  21. 21. 21 5.1 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 – Scalability Blueprint for Alfresco 5.1 – Sizing Guide for Alfresco 5.1 – AWS Reference architecture, implementation guide and CloudFormation template for Alfresco 5.0 and 5.1
