Backend issue: Performance and memory problem

[tshemsedinov]

All filters and transformations should be executed in database, not in app server memory

be-user-service/src/services/diiaId.ts

Lines 75 to 85 in b45a0e2

	async getIdentifierAvailability(userIdentifier: string, mobileUid: string): Promise<DiiaIdIdentifier[]> {
	await this.checkIfCreationExpiredAndSoftDelete(userIdentifier)
	const diiaIds: DiiaIdModel[] = await diiaIdModel.find({ mobileUid, userIdentifier, isDeleted: false })
	return diiaIds
	.filter((diiaId) => this.isDiiaIdActive(diiaId))
	.map(({ identifier, signAlgo }) => {
	return { identifier, signAlgo }
	})
	}
