tabul data fill --help

Tabul data fill
===============

Load generated data into data resources.

You select the data resources to be filled with:
   * the data selector argument (`target-selector...`)
   * and optionally the dependency option (`--with-dependencies`)

For more control on the data generated, you can add the data resource generators (`*--generator.yml`)
by selecting them with the generator selector option (--generator-selector)

This is an alias to the `transfer` command where:
  * the targets are the selected data resources
  * the sources are generated from the generator data resources and/of target metadatas

The default transfer operation is `upsert`.



Examples
--------

 1 - To load the table `D_TIME` from the connection `sqlite` with auto-generated data:


    tabul data fill D_TIME@sqlite


 2 - To load the table `D_TIME` with the data generation file `D_TIME--generator.yml` present in the current directory:


    tabul data fill --generator-selector D_TIME* D_TIME@connection


 3 - To load all data in the whole schema with the data generation file in the dir directory:


    tabul data fill --generator-selector dir/* *@connection


 4 - Load auto generated data into the table F_SALES and its dependencies


    tabul data fill --with-dependencies F_SALES@sqlite




Syntax
------


    tabul data fill [options|flags] <target-selector...>


where:


  Arguments:

    <target-selector...>                                          One or more data selectors that will select the target data resources to be filled.


  Cross Data Transfer Options:

    -bs,--buffer-size <buffer-size>                               defines the size of the memory buffer between the source and target threads

    -mdu,--metrics-data-uri <metrics-data-uri>                    defines a target data uri where the data metrics should be exported

    -out,--output-type <output-type>                              The resource that is passed as output

    -pt,--processing-type <processing-type>                       how to process the inputs (one by one or in batch)

    -sfs,--source-fetch-size <source-fetch-size>                  defines the size of the network message from the source to fetch the data

    -tmc,--transfer-mapping-columns <transfer-mapping-columns>    defines the columns mapping between the source and the target

    -tms,--transfer-mapping-strict <transfer-mapping-strict>      defines if a map by name or position is strict

    -op,--transfer-operation <transfer-operation>                 defines the transfer operation (insert, update, delete, upsert, merge, copy).

    -wp,--with-parameters                                         defines if parameters are used in the SQL statement


  Fill Options:

    -gs,--generator-selector <generatorSelector...>               One or more data selector that selects one or more data resource generator ( --generator.yml )

    -mrc,--max-record-count <maxRecordCount>                      This option defines the maximum total number of record that the data resource(s) must have when no data resource generator was found.


  Data Definition Options:

  Selection Options:

    -wd,--with-dependencies                                       If this flag is present, the dependencies of the selected target tables (ie parent/foreign tables) will be also be filled with data


  Global Options:

    -ah,--app-home <path>                                         The app home directory (default to the .tabul.yml file directory)
