Show HN: Flatsauce – Database with Decoupled Storage and Compute Hi HN, this is Soheil (https://flatsauce.com). Flatsauce is a cloud database service that separates storage from compute while horizontally scaling your database cluster. Think of it as a Postgres read/write cluster with several nodes except that all the nodes in Flatsauce share the same storage. Flatsauce intelligently routes data between the nodes and incorporates a file locking mechanism to ensure there is no data corruption. In traditional read/write replication scenarios usually a write instance is the source of truth. First data is written to the write server then the data is copied to all the read nodes. When more read nodes are needed to run long-running queries the storage needs to be copied for each node. Flatsauce reduces the cost to run a database cluster by eliminating the need to duplicate the data storage every time a new node is added to the cluster. February 24, 2022 at 01:16AM
Show HN: StreetComplete, an OpenStreetMap Editor for Humans StreetComplete is an OpenStreetMap[0] editor directed at people who want to contribute and want to do this using their smartphone, without learning how to edit things[1]. It is available as an Android application. It is intended to be used as one walks, with quests appearing as markers on the map. Selecting a marker allows one to answer a simple question. The answer will be added to the OpenStreetMap database, with app handling selecting objects for editing, transforming answer into OSM tags and making edits. OpenStreetMap account is needed to apply edits, but it is possible to start without it, make some edits and login/register later. Note: I am not the main author, but I am one of the active contributors. Github page is at https://ift.tt/2g8lasH and https://ift.tt/3nR9PzS shows what was recently released.
