It cannot wait for a server to tell it when to water. In the Alpha demo the sensor decides for itself when to open the irrigation valve, and it reports to the farm office in one small radio message a day. It runs the AltSql engine on 32 KB of flash with 672 bytes of engine RAM.</p> https://precomputing.com/altsql-mesh-keeps-twelve-devices-on-one-table-on-a-simulated-farm-with-no-signal-and-no-gateway/ Thu, 01 Oct 2026 00:00:00 +0000 https://precomputing.com/altsql-mesh-keeps-twelve-devices-on-one-table-on-a-simulated-farm-with-no-signal-and-no-gateway/ <p>Some places have no mobile coverage and nowhere to put a gateway. A big sheep farm is one. The people working it still need the same picture: which troughs are low, which gates are open, what jobs are waiting and how many sheep are where.</p> <p>AltSql Mesh gives every device its own copy of one shared table. Each device writes to its copy as its owner works. Whenever two devices come within radio range they bring each other up to date, over a link that may lose messages. No device is in charge and nothing waits for a server. Once every change has reached every device, all of them hold the same table, row for row, and any device with the memory for it can answer SQL about it.</p>
