To view the latest available version of the docs, see v24.2. rpk topic trim-prefix Trim records from topics This command allows you to trim records from topics, where Redpanda sets the LogStartOffset for partitions to the requested offset. All segments whose base offset is less then the requested offset are deleted, and any records within the segment before the requested offset can no longer be read. The --offset/-o flag allows you to indicate which index you want to set the partition’s low watermark (start offset) to. It can be a single integer value denoting the offset, or a timestamp if you prefix the offset with an '@'. You may select which partition you want to trim the offset from with the --partition/-p flag. The --from-file option allows to trim the offsets specified in a text file with the following format: [TOPIC] [PARTITION] [OFFSET] [TOPIC] [PARTITION] [OFFSET] ... or the equivalent keyed JSON/YAML file. Examples Trim records in 'foo' topic to offset 120 in partition 1: rpk topic trim-prefix foo --offset 120 --partition 1 Trim records in all partitions of topic foo previous to an specific timestamp: rpk topic trim-prefix foo -o "@1622505600" Trim records from a JSON file: rpk topic trim-prefix --from-file /tmp/to_trim.json Usage rpk topic trim-prefix [TOPIC] [flags] Aliases trim-prefix, trim Flags Value Type Description -f, --from-file string File of topic/partition/offset for which to trim offsets for. -h, --help - Help for trim-prefix. --no-confirm - Disable confirmation prompt. -o, --offset string Offset to set the partition’s start offset to, either as an integer or timestamp (@<timestamp-value>). -p, --partitions int32 int32Slice Comma-separated list of partitions to trim records from (default to all) (default []). --config string Redpanda or rpk config file; default search paths are /var/lib/redpanda/.config/rpk/rpk.yaml, $PWD/redpanda.yaml, and /etc/redpanda/redpanda.yaml. -X, --config-opt stringArray Override rpk configuration settings.
