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. ### Related Sections * [Resource Utilization](/condense/v2.4.0/other-features/resource-utilization) * [ksqlDB](/condense/v2.4.0/fully-managed-kafka/ksqldb) | Field | Description | Example | | ----------------------- | ------------------------------------------------------------------------- | ------- | | Replication Factor | Number of replicas for each partition.
