**What**
I have created a new method on the cart service which is `addLineItems`, allowing a user to add one or multiple items in an optimized way. Also updated the `generate` method from the line item service which now also accept a object data or a collection of data which. Various places have been optimized and cache support has been added to the price selection strategy.
The overall optimization allows to reach another 9000% improvement in the response time as a median (Creating a cart with 6 items):
| | Min (ms) | Median (ms) | Max (ms) | Median Improvement (%)
|---|:-:|---|---|---|
| Before optimisation | 1200 | 9999 | 12698 | N/A
| After optimisation | 63 | 252 | 500 | 39x
| After re optimisation | 56 | 82 | 399 | 121x
| After including addressed feedback | 65 | 202 | 495 | 49x
FIXES CORE-722
**What**
Fix system error (500) with DraftOrder create operation when payload includes discount in a tax-inclusive context.
**How**
* Ensure newly created cart contains all required relation in order to calculate line item tax-inclusive pricing with discounts.
* Add resilience to TotalsService.getLineDiscounts()
* Ensure newly generate line items have variant relation loaded.
* fix TotalsService.getLineItemTotals to use the passed lineItem instead of relying on cartOrOrder.items.
**Test**
* Unit:
* TotalsService.getLineDiscounts - coverage
* Integration:
* Admin API draft-order - coverage
* Admin API draft-order create w/ discount in tax-inclusive
Resolves: CORE-771

**what**
Support confirm of an order edit:
Upon confirmation, the items of the original order are detached and the items from the order edit are attached to the order.
The order total is recomputed with the correct total which can defer from the paid_total and refundable_amount (based on the paid_total)
**Tests**
- Unit tests medusa-js and medusa-react as well as the core
- Integration test of the confirmation flow which check that the order edit is properly confirmed and can be confirmed idempotently. Also validate the totals and that the order items correspond to the order edit items. Also validate the order totals.
FIXES CORE-498
**What**
- Implement adding a line item to order (edit)
**How**
- _by implementing the following "flow"_
- generate a line item
- computing line item adjustments for that line item
- creating tax lines
- creating a change record
**Testing**
- **_integration tests_**
- check if line item and order item change objects are created (with correct tax lines)
- line item adjustments are generated if
- fixed discount is applied to cart
- percentage discount is applied
- **_unit tests_**
- ensure that methods from Inventory, LineItem, LineItemAdjustment etc. services are called

**What**
Update the totals calculation on the refund line to include the notion of tax inclusive
**Test**
- Update and add new tests around the refund
Fixes CORE-482
* feat(medusa): Tax inclusive discounts calculations (#2137)
**What**
- Calculate line adjustments correctly taking into account the tax inclusivity
- fix totals getLineItemTotals by adjusting the sub total with the original tax amount instead of the tax amount when the unit price includes the taxes
**Tests**
- The tests create a cart with a percentage discount of 15%, the cart includes 2 items mixing the tax inclusive and validate the items on the result cart as well as the totals on each item. I ve based my calculation validation based on what we have done + some articles around discount apply on price without taxes to validate the output.,

* Modifies schema to allow SQLite as a DB driver. SQLite is preinstalled in most OSes allowing for minimal prerequisites in the installation process.
* Removes Redis dependency and replaces "real" redis instance with ioredis-mock this is not feature complete and errors are expected.
* Updates medusa new command to only ask for Postgres credentials if the starter template has database_type === "postgres" in medusa-config.js
* Small improvements to bin resolution
* Improvements to endpoint stability
- All schemas have been rewritten to a relational model
- All services have been rewritten to accommodate the new data model
- Adds idempotency keys to core endpoints allowing you to retry requests with no additional side effects
- Adds staged jobs to avoid putting jobs in the queue when transactions abort
- Adds atomic transactions to all methods with access to the data layer
