# Kafka Topics

![](https://mintcdn.com/zeliot/1mmppOlVvf6i8S0Q/images/condense/v2.4.0/fully-managed-kafka/rwKRGO3QthZ6EMqqYblg%252Fblobs%252FHdvkoGuHQ25BRv5yuMwS%252Fimage.png?fit=max\&auto=format\&n=1mmppOlVvf6i8S0Q\&q=85\&s=35b780be235d598b846ffc49533a7b93)

### Overview

The **Kafka Topics** page in Condense provides a management interface to view, create, and configure topics within a Kafka cluster. From this page, administrators can define replication and partitioning, adjust retention policies, and apply advanced topic-level settings without requiring direct Kafka CLI commands.

Path: **Kafka Management → Kafka Topics**

### Topic List

On the left-hand panel, Condense displays all existing topics in the connected Kafka cluster.

* Topics are listed alphabetically.
* A search box allows filtering by topic name.

* Selecting a topic loads its configuration details in the main panel.

### Topic Actions

For each topic, Condense provides the following actions in the top-right menu:

* **Messages** → Opens the message viewer for browsing records in the topic.
* **Edit** → Enables modification of topic configuration.

* **Delete** → Permanently deletes the selected topic from the cluster.

Additionally, the **Create Topic** button allows new topic creation with custom parameters.

### Basic Configuration

When creating or editing a topic, the following required fields must be defined

| Field | Description | Example |
| - | - | - |
| Replication Factor | Number of replicas for each partition. Ensures data availability. | `3` |
| No of Partitions | Number of partitions in the topic. Determines parallelism and throughput. | `6` |
| Retention Period (days) | Duration for which messages are retained in the topic before deletion. | `7` |

### Advanced Configurations

Advanced settings allow fine-grained control of topic behavior. These fields map directly to Kafka topic configuration parameters.

| Field | Description | Example |
| - | - | - |
| Cleanup Policy | Determines log cleanup strategy. Options: `Delete` (default), `Compact`. | `Delete` |
| Delete Retention Period (days) | How long delete markers are retained during log compaction. | `1` |
| Max Compaction Lag (ms) | Maximum time a record can remain uncompacted. | `9223372036854775807` |
| Max Message Size (bytes) | Maximum size of an individual message allowed. | `5242940` |
| Message Timestamp After Max (ms) | Upper bound for timestamp range in messages. | `9223372036854775807` |
| Message Timestamp Before Max (ms) | Lower bound for timestamp range in messages. | `9223372036854775807` |
| Message Timestamp Type | Defines how message timestamps are set. Options: `CreateTime`, `LogAppendTime`. | `CreateTime` |
| Min Compaction Lag (ms) | Minimum time a record must remain before compaction. | `0` |
| Min In-Sync Replicas | Minimum number of replicas that must acknowledge a write for it to succeed. | `1` |
| Retention Size (bytes) | Maximum total size of log segments retained before deletion. `-1` = unlimited. | `-1` |
| Segment Size (bytes) | Size of each log segment file before rolling. | `1073741824` |
| Segment Period (ms) | Time-based rolling interval for log segments. | `604800000` |

### Usage Notes

* All advanced fields correspond to Kafka’s topic-level configuration properties.
* Fields not explicitly set in Condense will use Kafka cluster defaults.
* Certain changes (e.g., partition count) are not reversible once applied.
* Care must be taken with retention and cleanup policies to avoid unintended data loss.
