Collections group related tables so your workflows and agents only reference what's relevant.

They help you scope AI retrieval, keep tables organized, and see at a glance which sources feed which use case. Collections are optional — they matter most once you have more than a handful of tables.
When to Use (and Not Use) Collections
Use a Collection when:
- You want to limit retrieval to a specific topic or knowledge domain
- A workflow or agent should only reference a defined set of tables
- You're managing multiple tables that belong to one process, team, or audience
Examples:
- Grouping SOP and policy tables for HR or compliance workflows
- Creating a collection of onboarding guides, templates, and customer FAQ tables
- Organizing financial tables for budgeting, forecasting, or spend approvals
You may not need a Collection when:
- You're working with just one or two general-purpose tables
- The table is referenced across many unrelated workflows
- You're testing or uploading content for a short-term use case
In those cases, using a table directly — without grouping it into a collection — is often faster.
What Collections Can Contain
Collections group tables regardless of how they were created:
Type
Examples
Native tables
Tables you built directly in MergeBase with a custom schema
Uploaded tables
Parsed from CSV, Excel, PDF, Word, or audio files
Connected tables
Synced from Salesforce, HubSpot, Google Sheets/Drive, Notion, Postgres, and other connected sources

What You'll See in the Interface
Each table shows its collection membership, along with:
- Table name and row/record count
- Source type (native, uploaded, or connected)
- Last sync time and status, for connected tables
- Workflow usage — where the table is referenced
Best Practices
Organize Clearly
- Group by function, team, or workflow
- Use descriptive collection and table names
- Keep a narrow scope per collection to avoid retrieval noise
Maintain Proactively
- Review and clean up collections periodically
- Remove or archive tables that are no longer used
- Monitor which workflows depend on which tables before removing or restructuring one
