fluvio topic subcommands are used to create and delete topics, as
well as to view basic information about existing topics.
This command is used to create new Fluvio topics.
Create a Topic with the given name fluvio topic create [OPTIONS] <name> Arguments: <name> The name of the Topic to create Options: -p, --partitions <partitions> The number of Partitions to give the Topic [default: 1] -r, --replication <integer> The number of full replicas of the Topic to keep [default: 1] -i, --ignore-rack-assignment Ignore racks while computing replica assignment -f, --replica-assignment <file.json> Replica assignment file -d, --dry-run Validates configuration, does not provision --retention-time <time> Retention time (round to seconds) Ex: '1h', '2d 10s', '7 days' (default) --segment-size <bytes> Segment size (by default measured in bytes) Ex: `2048`, '2 Ki', '10 MiB', `1 GB` --compression-type <compression> Compression configuration for topic --max-partition-size <bytes> Max partition size (by default measured in bytes) Ex: `2048`, '2 Ki', '10 MiB', `1 GB` -h, --help Print help information (use `--help` for more detail)
$ fluvio topic create greeting topic "greeting" created
Retention is a policy for how data is cleaned up from a topic.
In this example, the last segment of 500k will be deleted after 30 days.
$ fluvio topic create my-topic --retention-time '30 days' --segment-size 500000 topic "my-topic" created
This configuration will set compression at a topic level. When set producers are forced to use a compression algorithm that matches with the topic configuration. The SPU will reject any Produce request that does not match with the topic configuration.
--compression-type any is used, SPU will accept any compression algorithm.
$ fluvio topic create my-topic --compression-type gzip topic "my-topic" created
In this example, the topic
my-topic will be created with compression type
This command shows you all the existing topics in your cluster, as well as some basic information about them, including how many partitions a topic has and how many times it is replicated.
List all of the Topics in the cluster fluvio topic list [OPTIONS] Options: -O, --output <type> Output [default: table] [possible values: table, yaml, json] -h, --help Print help information
$ fluvio topic list NAME TYPE PARTITIONS REPLICAS IGNORE-RACK STATUS REASON greeting computed 1 1 resolution::provisioned
This command prints more detailed information about a specific topic.
Print detailed information about a Topic fluvio topic describe [OPTIONS] <name> Arguments: <name> The name of the Topic to describe Options: -O, --output <type> Output [default: table] [possible values: table, yaml, json] -h, --help Print help information
$ fluvio topic describe greeting Name : greeting Type : computed Partition Count : 1 Replication Factor : 1 Ignore Rack Assignment : false Status : provisioned Reason : -----------------
This command deletes an existing Fluvio topic and all data associated with it. This data may not be recovered, so use this with care.
Delete one or more Topics with the given name(s) fluvio topic delete [OPTIONS] <name>... Arguments: <name>... One or more name(s) of the topic(s) to be deleted Options: -c, --continue-on-error Continue deleting in case of an error -h, --help Print help information
