What is N1QL?

Flexibility of JSON

Power of SQL


How Does One Evaluate a Query Language?

ExpressiveDeclarativeEcosystem


N1QL is Expressive: E-Commerce Examples

SELECT product.name, SUM(items.count) AS unitsSold FROM purchases UNNEST purchases.lineItems AS items JOIN product ON KEYS items.product GROUP BY product ORDER BY unitsSold DESC LIMIT 10

SELECT SUBSTR(purchases.purchasedAt, 0, 7) AS month, ROUND(SUM(product.unitPrice * items.count)/1000000, 3) revenueMillionFROM purchases UNNEST purchases.lineItems AS items JOIN product ON KEYS items.product GROUP BY SUBSTR(purchases.purchasedAt, 0, 7) ORDER BY month


N1QL is Expressive: Image Processing Example

SELECT m.image AS gallery_image, s.image AS source_image, s.x, s.y, m.r AS gallery_r, m.g AS gallery_g, m.b AS gallery_b, s.r AS source_r, s.g AS source_g, s.b AS source_b,FROM SourcePixels sJOIN GalleryMeans m ON KEY s.rgb

Indexing


Why Do We Need Indexes?

Indexes are used to quickly look up objects

meeting user-specified criteria without having to search over every

object in the database.


What Are the Different Types of Indexes?

Primary IndexesSecondary Indexes

Spatial IndexesText Indexes


Index Types … Let’s Use the Library Analogy

Source: http://www.montel.com/en/markets/library/


Secondary IndexesLocal secondary indexes – Map/Reduce views in 3.0 Co-located with data Higher write performance Lower read performance: scatter-gather Scaling bottleneck with a high number of indexes or data

nodes

Global secondary indexes (GSI) – New in 4.0 Higher query performance Async writes to a large number of global indexes Independently scaled and partitioned Isolated from Key-Value operations


Box on Points Box Intersects Multi Dimensions Geo + Others

Spatial Indexes Experimental in 3.0, now GA in 4.0

– Performance and stability improvements GeoJSON output Bounding-box and range queries on multiple dimensions

Multi-Dimensional Scaling


Workload and ScalingHorizontal scaling Partitions a dataset onto one or more homogenous nodes Each node runs the same mixed workloads Re-partition dataset with additional hardware capacity

Multi-Dimensional ScalingIsolated Service for minimized interference Independent “zones” for query, index, and data services

Minimize indexing and query overhead on core key-value operations.

ForestDB: Next-Generation Storage Engine


Common Storage Structures – B+-Tree

26

Reads Writes EnginesB+-Tree Good read performance if the

fan-out is high (“short” tree) for small fixed-length keys. Read performance degrades for variable-length keys.

Update-In-Place results in random writes and bad write latency.Append-Only file improves write performance but requires periodic compaction.

Common Storage Structures – LSM-Tree

27

Reads Writes EnginesLSM-Tree

Reads may have to traverse multiple trees – typically worse than B+ tree.

WAL(Write-Ahead Log) improves writes within-memory trees that are appended to the end of the log.

Fast Storage – ForestDB

Fundamentally rethinking the requirements for fast storage Compact and efficient storage for a variety of data Unified engine that performs well for various workloads Unified engine that scales from small devices to large

servers Optimized for new SSD storage technology

ForestDB provides a compact index structure

that significantly reduces the disk I/Oand write amplification.

Trie (prefix tree) for which the nodes are B+-Trees– HB+-Trie was originally presented at ACM SIGMOD 2011 Programming

Contest, by Jung-Sang Ahn who works at Couchbase(http://db.csail.mit.edu/sigmod11contest/sigmod_2011_contest_poster_jungsang_ahn.pdf)

Couchbase Security Features

In a fewslides ..

33


External Identity Management Using LDAP

34

Centralized identity management Define multiple read-only admins and full-admins Centralized security policy management for

admin accounts for stronger passwords, password rotation, and auto lockouts

Individual accountability; simplified compliance Define UIDs in LDAP, and map UIDs to the read-

only/full admin role in Couchbase Comprehensive audit trails with LDAP UIDs in

audit records


Admin Auditing in Couchbase

35

Rich audit events Over 25+ different, detailed admin audit events Auditing for tools including backup

Configurable auditing Configurable file target Support for time-based log rotation and audit

filtering

Easy integration JSON format allows for easy integration with

downstream systems using flume, logstash, and syslogd


Auditing a successful login
