# Browsing data

::: note
In Aerospike, a **namespace** is similar to a database, a **set** is similar to a table, and a **record** is similar to a row. Unlike relational databases, Aerospike is schemaless: records in the same set can have different bins (columns).

For a deeper explanation, see the [Aerospike data model](https://aerospike.com/docs/database/learn/architecture/data-storage/data-model) documentation.

## Navigation hierarchy

Aerospike Voyager organizes data in the same hierarchy as Aerospike itself. You drill down through four levels:

### Clusters overview

The top-level view lists all connected clusters with their connection status (connected, disconnected, error). Click a cluster to see its namespaces.

### Namespace overview

Lists all namespaces in the selected cluster. Each namespace card shows the number of sets and storage usage.

### Set view

Lists all sets within a namespace along with their record counts. Click a set to browse its records.

### Records view

Records render as expandable cards in a scrollable list. Each card shows the record’s bins and metadata.

## Record cards

Each record card shows:

-   **Key and digest**: The record’s user key (if stored) and its digest (truncated hex hash), displayed in the card header. Click the copy icon next to the digest to copy the full value.
-   **Bins**: The key-value pairs stored in the record. Each bin displays its name, value, and a type badge.
-   **Metadata chips**: Summary information in the card header:
    -   **Gen**: The generation count (number of times the record has been written).
    -   **Exp**: The record’s expiration. Shows `Never` for records with no TTL, or the expiration timestamp.
    -   **Node**: The cluster node ID that owns this record.
    -   **Part**: The partition ID where this record is stored.
-   **Show N more bins**: If a record has more bins than the default display limit, click this link to reveal the rest.

## Type badges

Voyager displays the following Aerospike data types: String, Integer, Double, Boolean, List, Map, Bytes, GeoJSON, and HLL. Each bin value carries a type badge in the UI (rendered with the lowercase identifier, for example `string`, `integer`, `double`).

## Nested data expansion

List and map bins can contain nested structures at any depth. Click the expand arrow next to a list or map bin to drill into its contents using an inline tree view. Each nested level indents further and displays its own type badges. Use the **Expand bins one level** and **Collapse bins one level** buttons in each record card’s header to expand or collapse all bins at once.

## Pagination

Records are paginated to keep the interface responsive. The default page size is **25 records per page**. You can change this in **Settings** (range: 1 to 50 records per page). Use the pagination controls in the toolbar above the records to navigate between pages.

## Record lookup

To jump directly to a specific record, click the **Search by key or digest** icon in the toolbar above the records. You can search by:

-   **User key**: The application-level key you used when writing the record (available only if the record was written with the “[send key](https://aerospike.com/docs/database/learn/policies)” option enabled).
-   **Digest**: The 20-byte hash that Aerospike uses internally to identify every record. Enter the digest as a hex string.
