Statuses While the specific details are not publicly disclosed by WhatsApp, we can explore a likely scenario based on industry practices and common database functionalities. Here's how delivery statuses might be handled within WhatsApp's databaseMessage Table The Heart of CommunicationThe core table likely responsible for storing message information is likely called "messages" or something similar. This table would hold various fields, includingUnique message identifier primary keySender and recipient informationMessage content text, emojis, etc. - potentially encryptedTimestamps sentreceivedA dedicated field for the message status "Sent," "Delivered," "Read"Status Updates A Dynamic ProcessWhen you send a message, its initial status in the database is likely set to "Sent."As the message interacts with the recipient's device and WhatsApp servers, the status field in the database is updated accordinglyDelivered When the message reaches the recipient's device assuming an internet connection, the status might be updated to "Delivered.
" This likely involves some form of acknowledgment signal sent back to the server.Read WhatsApp's "Read" receipts are a bit more complex. The specific mechanism might involveRecipient's Device Activity When the recipient opens the chat containing the Tajikistan Email List message on their device, an indicator might be sent back to the server. The sender's database would then be updated to reflect a "Read" status.Read Receipts Settings Users can enable or disable "Read Receipts" in their settings. If disabled, the sender's message might remain as "Delivered" even after the recipient views it.Server-side Management The Central HubThe WhatsApp server likely plays a crucial role in managing message delivery statuses. Here's what the server might doCommunication with Devices The server communicates with user devices to track their onlineoffline status and facilitate message delivery.
Status Updates Upon receiving delivery confirmations or read receipts from recipient devices, the server updates the message status in its own database and potentially relays it to the sender's device for update in the local database.Local Database Caches Keeping It Offline-ReadyEach user device likely maintains a local copy of the message database like the SQLite database on Android. This local database stores message content, timestamps, and the corresponding status for offline access.When a user comes online, the local database synchronizes with the server to ensure message history and statuses are consistent across devices.Limitations and ConsiderationsWhile the system described above offers a possible explanation, it's important to acknowledge some limitationsPrivacy and Encryption The exact encryption practices for message content and delivery statuses within the database remain unclear.
