Food & drinks will be provided. Hope to see you there! --Talks-- --Solr's AutoScaling Framework, Presenter: Varun Thacker, Solr Committer, Lucidworks-- The goal of Solr's AutoScaling framework is for search clusters to be able to grow to a trillion documents without much human intervention. We'll discuss practical use-cases to keep the cluster healthy and performing optimally, complete with fault tolerance. For example, we'll cover how to achieve these scenarios by utilizing the framework. - Effectively managing disk space by setting triggers and sending out alerts. - Maintaining a minimum replication factor when nodes go down. We'll also use rules to make sure the replicas are spread out, thus maximizing fault tolerance. The talk will cover how to use the suggestions end-point to know the violations in your cluster. --Search Infra @ Reddit: Challenges in Scaling to Millions of Cat Posts, Presenter: Jerry Bao, Software Engineer, Reddit-- As Reddit continues to grow year after year, Search has become a vital part of the Reddit experience, both internally and externally. Come learn about the tools we’ve used, challenges we’ve faced, and lessons we’ve learned rebuilding and scaling our search infrastructure to the next million cat posts.

  • SolrCloud Rebalance API at Bloomreach

    BloomReach Headquarters

    Join us for a Meetup at Bloomreach for the below presentation. Food & drinks will be provided. 6:00pm - 6:30pm: Food, drinks, networking 6:30pm: Presentation SolrCloud Rebalance API at Bloomreach: Presented by Suruchi Shah and Nitin Sharma, Bloomreach SolrCloud with large data sets and collections usually run into unevenly balanced clusters. This causes skewed data and replica distribution across solrcloud nodes. Automatic Node Discovery in an existing cluster does not cause data to be re-distributed. Dynamically scaling up or scaling down collections based on index/config size or cluster size is non trivial and poses operational overhead. Rebalance API offers a flexible way of redistributing data in SolrCloud while guaranteeing zero downtime. It offers multiple scaling strategies that aid in smarter/faster index manipulation and multiple allocation strategies that offer smarter collection placement in the cluster. It also offers a platform for users to write their own scaling strategy as they see fit. The api has been built in an open source friendly fashion.

Hope to see you there! Building Search At Airbnb using Lucene, Presented by Mousom Dhar Gupta, Airbnb Airbnb has experienced exponential growth in recent years. Not only has our data and number of users been growing exponentially but so has the complexity of our search algorithms as we've wanted to do more to better match our Hosts with our Guests. Our team has learned to mix the best features of Lucene while augmenting them with in-house, custom-built technologies to build a scalable, efficient but simple Search infrastructure which will all be shared in this talk. Speaker Bio: Mousom Dhar Gupta has been a engineer at Airbnb Search and Marketplace Infrastructure team since last year. He focuses on building and scaling Search and other services like Calendar, Social Connections etc. Before Airbnb, he was at Facebook , Netflix and Amazon working on various product backends (Java) like Facebook Messenger, Amazon Kindle etc. Introduction to Security in Solr, Presented by Anshum Gupta, Lucidworks Apache Solr has evolved into a highly scalable system, capable of handling a lot of data and high number of queries but only recently was a mechanism to secure access in Solr provided. Apache Solr 5.2 shipped with pluggable authentication and authorization modules. These modules enable users to write their own plugins for managing security in Solr. This talk would cover an overview of both, the authentication and authorization frameworks, and how they work together within Solr. It will also provide an overview of existing plugins and how to enable them to restrict user access to resources within Solr. Speaker Bio: Anshum Gupta ia a committer and PMC member on the Apache Lucene / Solr project with over 10 years of experience with search and related technologies. He currently works at Lucidworks and spends most of his time working on SolrCloud i.e. the distributed feature set of Apache Solr. Prior to joining Lucidworks, he was a member of the team that developed and launched AWS CloudSearch - The AWS search as a service offering. He was also a key contributor in the search teams at various start ups.
