How SQLiteEdge Computes SQLite 3.46 WAL PRAGMAs, mmap Memory & Public Cloud Cost Models
Every configuration parameter, RAM threshold, and vendor cost comparison on SQLiteEdge is calculated deterministically from official SQLite 3.46 documentation, Litestream/LiteFS specifications, and public vendor pricing retrieved 2026-11-12.

SQLiteEdge Single-Writer WAL Lock & Synchronous Durability Rules
In SQLite Write-Ahead Logging (`PRAGMA journal_mode = WAL`), read transactions execute concurrently across CPU cores while write transactions serialize through a single per-file write lock. Under official SQLite documentation, `PRAGMA synchronous = NORMAL` appends frames to the `-wal` file in OS memory and issues storage sync barriers on WAL checkpoints, whereas `PRAGMA synchronous = FULL` forces an `iodepth=1` storage sync on every commit. Where physical hardware latency telemetry is referenced, raw host-level `fio` verification remains `direct host-level telemetry verification on your target instance` and operators should run the verification command on their provisioned node.

SQLiteEdge Page Heap (`cache_size`), `mmap_size` & 2.3x NVMe Guard
Our SQLiteEdge configurator allocates 25% of selected VPS RAM to SQLite internal page cache using negative KiB notation (`PRAGMA cache_size = -(RAM_MiB * 0.25 * 1024)`). On standard local ext4/XFS filesystems, SQLiteEdge sets `PRAGMA mmap_size` to `min(DB_Bytes, 50% VPS RAM, 32 GiB)` to avoid redundant `read()` copy overhead; when LiteFS FUSE replication is selected, SQLiteEdge sets `PRAGMA mmap_size = 0` per LiteFS FUSE guidance. Minimum disk sizing applies a 2.3x multiplier over raw `.sqlite3` size plus 15 GB OS headroom to accommodate uncheckpointed `-wal` bursts and online `VACUUM INTO` snapshots.

SQLiteEdge Public Cloud vs Local NVMe Cost Equations (Retrieved 2026-11-12)
All vendor tariffs cited on SQLiteEdge were retrieved on 2026-11-12 from official public checkout pages (`https://www.hostinger.com/vps-hosting`, `https://www.vultr.com/pricing/`, `https://ultahost.com/vds-hosting`, `https://www.interserver.net/vps/`, and `https://chemicloud.com/wordpress-hosting`). Promotional and renewal prices change frequently, so always confirm final billing terms on the vendor checkout screen before purchasing.

SQLiteEdge Consolidation Into DokployHub & Affiliate Governance
Because production SQLite apps almost always co-locate alongside reverse proxies and Docker web services on one VPS, active editorial updates are consolidated into DokployHub (`https://dokployhub.pages.dev`), while SQLiteEdge stays online under unindexed reference status governance as a permanent `PRAGMA` reference archive.
