Tabli - Data Tail Command

Undraw Windows


The data tail command print only the N last records of a data resource.

This command is useful to print content of data resource that have a big size.

To print a data resource, you can also use:

  • the print command to print the whole content of a data resource
  • the head command to print the whole content of a data resource


tabli data tail -h
Tabli data tail

Print the last N rows of content of data resources.

By default, there is a limit of 10 on the number of rows printed


 1 - Show the first 10 records data of the table `sales` from the data store `sqlite`:

        tabli data tailsales@sqlite

 2 - Show the last 500 rows of the table `time` from the data store `postgres`:

        tabli data tail --limit 500 time@postgres

 3 - Show the last 10 lines from the file `request.log`:

        tabli data tail request.log

  Global Options:

    -cf,--conf <path>                                       The path to a configuration file

    -ns,--not-strict                                        A minor error will not stop the process.

    -odu,--output-data-uri <outputDataUri>                  defines the output data uri for the feedback data (default: console)

    -oo,--output-operation <dataOperation>                  defines the data operations (replace, truncate) on an existing output resource before transfer.

    -oop,--output-transfer-operation <transferOperation>    defines the output transfer operation (insert, update, merge, copy). Default to `copy` for a file system and `insert` for a database.

    -pp,--passphrase <passphrase>                           A passphrase (master password) to decrypt the encrypted values


We don't recommend to increase the rows limit to a very high number.
This command loads the data into memory to calculate the data layout and
render data aligned properly.
Increasing the limit will then increase the memory footprint and may cause an out-of-memory error.
