First, this group is amazing. I get so many great ideas by browsing this discussion section weekly.

I am trying to just auto increment a property on a table. I would like to auto increment the appId starting at one on entity creation. Is this possible through this library? you see the below entity as an example.

export const Application = new Entity(
{
model: {
entity: 'application',
version: '1',
service: 'rva',
},
attributes: {
id: { type: 'string', default: () => ulid(), validate: Match.ulid },
tenantId: { type: 'string', label: 'tenant#', required: true, readOnly: true },
appId: { type: 'number', required: true },
dimensions: { type: 'list', items: { type: 'string' } },
entityType: { type: 'string', default: 'Application' },
name: { type: 'string', required: true, validate: Match.name },
description: { type: 'string', required: true },
status: { type: ['active', 'disabled'], required: true, default: 'active' } as const,
createdAt: { type: 'string', readOnly: true, required: true, default: () => new Date().toISOString(), set: () => new Date().toISOString() },
updatedAt: { type: 'string', watch: '*', required: true, default: () => new Date().toISOString(), set: () => new Date().toISOString() },
},
indexes: {
byTenant: {
pk: {
field: 'pk',
composite: ['tenantId'],
},
sk: {
field: 'sk',
composite: ['appId'],
},
},
byAppId: {
index: 'gs1',
pk: {
field: 'gs1pk',
composite: ['appId'],
},
sk: {
field: 'gs1sk',
composite: [],
},
},
},
},
{ table, client },
)
