How to Approach Tasks

1. Classify the request:

   • Search / Spotter -- Load references/architecture.md for search-token architecture, Sage, Spotter agents
   • Models / semantic layer -- Load references/best-practices.md for Model design, dimensions, measures, join patterns, Spotter optimization
   • SpotIQ / insights -- Load references/diagnostics.md for algorithm tuning, insight quality, performance
   • Liveboards / visualization -- Load references/best-practices.md for Liveboard design, complexity limits, scheduling
   • Embedding / SDK -- Load references/best-practices.md for Visual Embed SDK patterns, authentication, multi-tenancy, custom actions
   • TML / CI/CD -- Load references/best-practices.md for TML management, version control, FQN references, package management
   • Performance -- Load references/diagnostics.md for search performance, warehouse optimization, SpotCache
   • Connectivity -- Load references/diagnostics.md for connection troubleshooting (Snowflake, BigQuery, Databricks)
   • Security / governance -- Load references/best-practices.md for RLS, CLS, sharing, groups, SpotCache security
   • Cluster health (on-prem) -- Load references/diagnostics.md for Falcon engine, node failures, memory, logs

2. Identify deployment model -- Determine whether the user runs ThoughtSpot Cloud (live query to cloud warehouses, SpotCache, managed infrastructure) or ThoughtSpot Software (Falcon in-memory database, self-managed clusters). Cloud uses live query architecture; Software includes the Falcon engine for local data storage.

3. Load context -- Read the relevant reference file for deep technical detail.

4. Analyze -- Apply ThoughtSpot-specific reasoning. Consider the data warehouse backend (Snowflake, BigQuery, Databricks, Redshift), embedding requirements, user audience (business users vs developers), and whether the question involves search optimization or traditional dashboard design.

5. Recommend -- Provide actionable guidance with TML examples, SDK code snippets, Model design patterns, SpotIQ tuning parameters, or warehouse optimization recommendations.

6. Verify -- Suggest validation steps (Performance Tracking Liveboard, AI/BI Stats data model, Developer Portal Playground for embedding, SpotIQ feedback loop).

Platform Overview

ThoughtSpot is an AI-driven, search-based analytics platform that differentiates through natural language search, AI-powered insights (SpotIQ), and comprehensive embedded analytics (ThoughtSpot Everywhere). Over 64% of customers use Spotter as their primary analytics interface, with platform usage surging 133% year-over-year (end of fiscal 2025).

Architecture Pillars

1. Patented Search-Token Architecture: Parses natural language queries into structured tokens mapped to a governed semantic model, generating deterministic SQL rather than relying solely on LLM text-to-SQL
2. Falcon In-Memory Calculation Engine: Proprietary columnar in-memory database for sub-second query performance (primarily used in ThoughtSpot Software)
3. Cloud-Native Live Query: Connects directly to cloud data warehouses (Snowflake, BigQuery, Databricks, Redshift) without data movement, with SpotCache for cost-controlled caching

Deployment Models

| Aspect | ThoughtSpot Cloud | ThoughtSpot Software | |---|---|---| | Hosting | Fully managed SaaS | Self-managed on-premises | | Data Storage | Live query to cloud warehouses + SpotCache | Falcon in-memory database + connections | | Updates | Continuous monthly releases | Manual upgrade cycles | | Infrastructure | Managed by ThoughtSpot | Customer-managed clusters | | Best For | Cloud-native organizations | Data residency/compliance requirements |

Search-Based Analytics

Search-Token Architecture

ThoughtSpot's core innovation. Users type natural language questions into a search bar to generate visualizations:

1. User types a question (e.g., "revenue by region last quarter")
2. The system parses the input into structured tokens mapped to data objects (columns, tables, measures, attributes) in the semantic model
3. Tokens are translated into deterministic SQL
4. SQL executes against the data warehouse
5. Results render as an automatically selected visualization

Sage Search Engine

Integrates generative AI (GPT-based models) with the search-token architecture:

• Understands complex, multi-step analytical questions
• Supplements LLM algorithms with metadata (attribute columns, synonyms, indexed values, formulas, join paths, analytical keywords)
• Generates SQL that respects security controls and business logic from the semantic model
• Provides explanations of how queries were interpreted

Analytical Keywords

ThoughtSpot supports keywords that modify search behavior: "top 10", "bottom 5", "growth of", "daily", "weekly", "monthly", "quarterly", "yearly", "vs last year", "average", "by", "for each".

Spotter AI Assistant

Spotter 3 (Current)

• Conversational analytics: users interact with data through natural language
• Context-aware: maintains conversation context across follow-up questions
• Visualization generation: automatically selects appropriate chart types

Reinforcement Learning

• Usage-based ranking algorithm prioritizes relevant insights
• Thumbs-up/thumbs-down feedback mechanism trains the system
• Supervised learning understands user preferences for insight types

Models (Semantic Layer)

Models are the next-generation semantic layer replacing Worksheets:

• Define dimensions, measures, relationships, and business logic in a governed, reusable structure
• Best practice: connect all Answers and Liveboards to Models, not directly to Tables or Views
• Simplifies TML management (single Model reference vs. multiple table references)
• Spotter optimization tab for indexing, date validation, and column type configuration

TML (ThoughtSpot Modeling Language)

YAML-based configuration-as-code for all ThoughtSpot objects:

• All objects (Tables, Models, Worksheets, Answers, Liveboards, Monitor alerts) can be exported/imported as TML
• Enables version control, CI/CD pipelines, and programmatic management
• Python library: thoughtspot-tml (PyPI) for programmatic manipulation
• FQN (Fully Qualified Name): disambiguates objects with the same name; required when multiple connections or tables share names; always include before importing

ThoughtSpot Everywhere (Embedding)

Visual Embed SDK

JavaScript/TypeScript library (@thoughtspot/visual-embed-sdk):

| Component | Description | |---|---| | LiveboardEmbed | Embed a single visualization or full Liveboard | | SpotterEmbed | Embed the Spotter AI search and analytics experience | | SearchEmbed | Embed the full ThoughtSpot Search page | | SearchBarEmbed | Embed only the ThoughtSpot search bar | | AppEmbed | Embed the complete ThoughtSpot application |

Authentication for Embedding

Delivery: email, in-app notifications. TML support for export/import as code.

Security

• Row-Level Security (RLS): restrict data at the row level based on user/group; rule-based and ACL approaches
• Column-Level Security (CLS): control visibility of specific columns per user/group
• Object-level sharing: content accessible only when explicitly shared
• Group-based access: hierarchical group structures for managing permissions
• SOC 2 Type II certified, GDPR compliant
• AWS PrivateLink for secure network connectivity

Anti-Patterns

1. "Connecting Answers directly to Tables." Always connect Answers and Liveboards to Models, not directly to Tables or Views. Models provide governed dimensions, measures, business logic, and a single reference point that simplifies maintenance and TML management.

2. "Multiple Models per Liveboard." Using multiple Models on a single Liveboard creates cross-model conflicts and unpredictable join behavior. Use one Model per Liveboard for all visualizations.

3. "Importing TML without FQN references." When multiple connections or tables share names, TML import fails or maps to the wrong objects. Always add fqn parameters to TML before importing.

4. "Over-indexing high-cardinality columns." Indexing columns with millions of unique values (transaction IDs, timestamps) consumes excessive memory and slows search suggestions. Index only frequently searched columns like product names, regions, and categories.

5. "Ignoring SpotCache security." SpotCache does not inherit security controls from the source warehouse. RLS and CLS must be applied manually on cached datasets. Failing to do so exposes data to unauthorized users.

6. "No search optimization on Models." Without enabling Spotter optimization (indexing, date format validation, column type review), search quality degrades. Users get wrong suggestions, incorrect token matching, and poor search relevance.

7. "Embedding without prefetch." Loading embedded ThoughtSpot components without calling the SDK's prefetch method before init causes slow initial render times. Prefetch caches static assets early.

8. "Using cookie-based auth in embedded contexts." Modern browsers block third-party cookies. Use cookieless trusted authentication for embedded deployments to avoid silent authentication failures.
