Batch Table Schema
|
|
==================
|
|
|
|
From a schema standpoint there are 2 types of batches generally speaking:
|
|
static and dynamic.
|
|
|
|
Static batch types have 2 "dedicated" tables within the ``default`` schema of
|
|
the DB: one table for the batch "headers" and another for its "data". For
|
|
instance the basic inventory batch uses these tables:
|
|
|
|
* ``batch_inventory``
|
|
* ``batch_inventory_row``
|
|
|
|
When a new inventory batch is created, 1 new ``batch_inventory`` record is
|
|
created but multiple new ``batch_inventory_row`` records may be created. The
|
|
latter table contains all rows for all inventory batches.
|
|
|
|
Dynamic batch types however are just that, and do not have a dedicated "data"
|
|
table, although they still do have a dedicated "header" table. For instance
|
|
this approach is used for "importer batches" - when running an importer creates
|
|
a batch, it will create 1 new ``batch_importer`` record but then will create a
|
|
brand new table with custom schema based on the importer, to hold the data.
|
|
|
|
To avoid cluttering the ``default`` schema within the DB, dynamic batch data
|
|
tables are not stored there. Instead they are kept within the ``batch``
|
|
schema, which must be manually created if you need it.
