# Sharding

Flow: 

    HomeScreen -> HomeScreenManager -> ThreadManager -> PointManager | ShardManager

* current Point = Point/Shard currently in focus on screen

* new Point = Point/Shard created when new Prompt sent

**1. Prompt**

1. 1. Table - code Flow:

|HomeScreen |HomeScreenManager |ThreadManager |PointManager |Cases: |

|--|--|--|--|--|

|onPrompt  |handlePropmt  |insertNewPoint  |createNewPoint  |  |

|  |  |  |  |1. Start Thread - New Root  |

|  |  |  |  |2. Under Regular Point Child  |

|  |  |  |  |3. Under Point that is a Shard Child - no Sharding  |

1. 2. Table - Point/Shard states:

| | |1. Start Thread - New Root |2. Under Regular Point Child |3. Under Shard Child - no Sharding |

|--|--|--|--|--|

|new PointDTO  |id |= new id  |= new id  |= new id  |

| |parentId  |= new id  |= currentPoint.parentId  |= currentPoint.parentId  |

| |parentShardId  |null  |null  |= currentPoint.ShardId  |

| |  |  |  |  |

|parent ShardDTO |shardPointChildren  |no change  |no change  |= add newPoint.id  |

| |  |  |  |  |

|parent PointDTO |pointChildren  |no change  |= add new id  |= no chnage  |  

**2. SubPrompt - Sharding**

2. 1. Table - code Flow

|HomeScreen |HomeScreenManager |ThreadManager |ShardManager |Cases: |

|--|--|--|--|--|

|onSubPrompt  |handleSubPropmt  |insertNewPoint  |createNewPoint  |  |

|  |  |  |  |1. Under Regular Point - 1st Sharding  |

|  |  |  |  |2. Under Existing Shard - 2nd Sharding  |

2. 2. Table - Point/Shard states:

| | |1. Under Regular Point - 1st Sharding |2. Under Existing Shard - 2nd Sharding |Differences  |

|--|--|--|--|--|

|new PointDTO  |id |= new id  |= new id  |same  |

| |parentId  |= currentPoint.id  |= currentPoint.id  |same  |

| |parentShardId  |null  |null  |same  |

| |  |  |  |  |  |

|current ShardDTO |shardId  |= new shardId  |= new shardId  |same  |

| |shardPointChildren  |= add newPoint.id  |= add newPoint.id  |same  |

| |  |  |  |  |

|current PointDTO |shardList  |= add newShardId  |= add newShardId  |same  |

| |  |  |  |  |

|new PointDTO |parentShardId  |= newShardId  |= newShardId  |same  |

| |  |  |  |  |

# **** Important:

Difference between 1st and 2nd Sharding:

* on 1st Sharding - shardsList = null -> Shard just added to empty list

* on 2nd Sharding - shardsList != null -> Shard needs to be inserted into the list at certain index
