Every CLI command supports succinct help right from the command line. Simply add
-h to the command line, or use the
help command before the command(s) in question.
# Display a summary of all commands. decodable help decodable -h # Same as above. # Display the help for the pipeline command. decodable pipeline -h decodable help pipeline # Same as above. # Display help for the create subcommand of the pipeline command. decodable pipeline create -h decodable help pipeline create # Same as above.
While the CLI has descriptive names for commands such as
pipeline, it can become verbose once you're accustomed to working with Decodable. Most commands support abbreviations and even aliases to make your life a little easier. All of these are listed in the help of each command. For example:
decodable connection -h # Output: # Manage connections # # Usage: # decodable connection [command] # # Aliases: # connection, conn # # ...
conn is an alias for
connection. Here are a few others:
|Command or Subcommand||Aliases|
A few commands - especially those that deal with SQL statements and other long strings - support reading from and/or writing to standard in and out, respectively. This makes it easy to script complex operations in a "Unix-like" way.
For example, the
pipeline command uses standard in. While you can provide the SQL directly on the command line,
# Providing SQL on the command line to `create`: decodable pipeline create "INSERT INTO ... SELECT ..."
you can also use the literal string
- (a single dash) to tell the CLI to read from standard in instead.
# A single dash tells the CLI to read from stdin. cat somefile.sql | decodable pipeline create - --name my-pipeline
config setup command is another example. Instead of writing the generated configuration to its default location, use
-o - to write it to stdout instead!
decodable config setup my-account -o - # Output: # # Decodable configuration file. # # # # Generated by esammer, 2021-08-07T18:27:18-07:00 # # version: 1.0.0 # active-profile: default # # profiles: # default: # account: my-account
Working with multiple Decodable accounts is easy. The CLI supports storing and switching between profiles, each with their own configurations, including the account. You can also use the
-p <profile> option to specify a profile for almost any command.
You can list all profiles and see which one is currently active (i.e. used by default), using the
config profile list command.
decodable config profile list # Output: # profile name account active # dev my-account-dev true # prod my-account false
You can edit the YAML configuration file with your favorite editor. It's in
~/.decodable/config by default.
# Decodable configuration file. # # Generated by esammer, 2021-04-30T15:20:17-07:00 version: 1.0.0 active-profile: dev profiles: dev: account: my-account-dev prod: account: my-account
By default, commands use whichever profile is marked as the
active-profile, but you can override that using the
-p <profile> argument to most commands.
# Uses the currently active profile (dev). decodable pipeline create ... # Use the prod profile instead. decodable pipeline create -p prod ...
Want to know how your job is doing? Pipelines and connections will output throughput metrics telling you how many records and bytes they are currently processing, as well as how many they have processed in their lifetime of being activated.
decodable pipeline get 37c0ea06 # test # id 37c0ea06 # version 1 # is latest true # target state RUNNING # actual state RUNNING # requested tasks 1 # actual tasks 1 # description INSERT INTO envoy_processed # create time 2022-01-10T18:54:47Z # last runtime error <none> # input metrics # envoy_raw 0.5 records / 106.8 B per second | 8.2 K records / 1.7 MB total # output metrics # envoy_processed 0.5 records / 106.8 B per second | 8.2 K records / 1.7 MB total # # SELECT * FROM envoy_raw
For pipelines, metrics are available for each input or output stream. For connections, a single set of metrics is available for their throughput to their associated stream.
