Description: In this course, understands working with Apache Cassandra. Apache Cassandra – a distributed database management system relating to noSQL-class systems and designed to create a highly scalable and reliable storage of huge amounts of data, presented in the form of hash. (Description taken from wiki) xIntro to Clustered - Distributed - NoSQL - Database - Cassandra DB Introduction – Cassandra DB – Features – Discussion NoSQL Discussion Features and Benefits of Cassandra DB Data Distribution – Peer-to-Peer Data replication strategies Scalability implementation Data-Center fault-tolerance Various features Explore Cassandra Cluster Topology (CCT) Single-Node – Implementation Identify and obtain sources Prep cluster nodes with Java environments Ensure cross-platform support Peruse configuration hierarchy Tweak initial settings – ante-cluster invocation Identify key network sockets Start instance of Cassandra Evaluate footprint Evaluate results Cassandra CLI Discuss applicability – Legacy support – et cetera Reveal cluster details using CLI Define sample key space Discuss data-types supported Set | Get | Delete simple records Evaluate data representation Drop key space accordingly Evaluate results Cassandra Query Language (CQL) Client Contrast with Legacy Cassandra CLI client Reveal cluster details via CQL Create | Drop key spaces Create Column Families (CF) Populate CF with rudimentary values for general usage Query CF using standard CQL lingo Explore Indices Update data as needed [Dis]Connect as needed Evaluate environment and prepare for usage Multi-Node – Cluster – Configuration – Deployment Highlight benefits of distributed | peer-to-peer environment Identify other nodes for inclusion Discuss data replication strategies Discuss tokenizationa and virtual nodes support Peruse and update primary Cassandra configuration for multi-node support Restart services and confirm data-availability Introduce new nodes to Cassandra cluster Query data accordingly Update data replication to target an ideal number of nodes Confirm availability of data across nodes Prep configuration for other nodes Distribute configuration using parallel SSH (pssh) as needed Add remaining nodes to cluster Evaluate current configuration Fail nodes arbitrarily and confirm data-survival Cassandra Node Management Discuss available tools: Commercial | Open Source Expose Cassandra Cluster configuration Reveal cluster network details Abbreviate cluster data and evaluate Decommission node as desired for hypothetical scenario Discuss various Cassandra protocols Consistency Levels – Affirmatives | Negatives Highlight default configuration Contrast various approaches with respect to risk-tolerance Discuss tunable consistency levels Set Client Read | Write consistency levels Evaluate data access post-consistency tweak Repair data consistency across nodes Confirm QUORUM-level consistency on ALL nodes of cluster Evaluate results Node Issues Introduce Hypotheticals Identify current data repositories Fail redundant nodes and access data Vary consistency level to reflect shifts in cluster dynamics Confirm data-accessibility Discuss tradeoffs of relegated stance Up replication of data to reflect current cluster description Down ALL nodes responsible for data and evaluate Recover accordingly Discuss risks and evaluate Multiple Data Centers (DCs) – Custom Replication Discuss available algos Define accurate topology map for Cassandra Cluster Update cluster configuration and re-initialize the cluster Define new – simple key space for multi-DC replication Reveal current multi-DC topology Ensure data are replicated accordingly Update existing key space to support multiple DCs Evaluate configuration Data Snapshots – Restoration Explore available tools Discuss backup | restoration model Snapshot single node and evaluate traces Use ‘pssh’ to snapshot ALL nodes Confirm existence of various snapshots on various nodes Purposely remove data Confirm cluster-wide updates reflecting lost data Restore key space as needed Confirm availability Year: 2013 Manufacturer: LinuxCBT Manufacturer Website: http://www.linuxcbt.com Author: Dean Davis Duration: 8 Hours Distributed by type of material: Video Tutorial Language: English 1.32 GB Download uploaded http://uploaded.net/file/t4inbz4x/LinuxCBT.CassDB.Edition-d3x.part1.rar http://uploaded.net/file/l5pbbipl/LinuxCBT.CassDB.Edition-d3x.part2.rar http://uploaded.net/file/89c6vqzv/LinuxCBT.CassDB.Edition-d3x.part3.rar http://uploaded.net/file/j418uvx4/LinuxCBT.CassDB.Edition-d3x.part4.rar http://uploaded.net/file/52iavivo/LinuxCBT.CassDB.Edition-d3x.part5.rar http://uploaded.net/file/qcnxu5qb/LinuxCBT.CassDB.Edition-d3x.part6.rar Download 百度云 以下隐藏内容只提供VIP赞助会员 sorry!
