This change introduces additional processes to manage snapshot uploading for E2 snapshots: ## erigon snapshots upload The `snapshots uploader` command starts a version of erigon customized for uploading snapshot files to a remote location. It breaks the stage execution process after the senders stage and then uses the snapshot stage to send uploaded headers, bodies and (in the case of polygon) bor spans and events to snapshot files. Because this process avoids execution in run signifigantly faster than a standard erigon configuration. The uploader uses rclone to send seedable (100K or 500K blocks) to a remote storage location specified in the rclone config file. The **uploader** is configured to minimize disk usage by doing the following: * It removes snapshots once they are loaded * It aggressively prunes the database once entities are transferred to snapshots in addition to this it has the following performance related features: * maximizes the workers allocated to snapshot processing to improve throughput * Can be started from scratch by downloading the latest snapshots from the remote location to seed processing ## snapshots command Is a stand alone command for managing remote snapshots it has the following sub commands * **cmp** - compare snapshots * **copy** - copy snapshots * **verify** - verify snapshots * **manifest** - manage the manifest file in the root of remote snapshot locations * **torrent** - manage snapshot torrent files |

Erigon-API
Erigon-API is a set of tools for building applications containing Erigon node.
Our own binary erigon is built using it.
Modules
-
cli- erigon-cli, methods & helpers to run a CLI app with Erigon node. -
node- represents an Ethereum node, running devp2p and sync and writing state to the database. -
stagedsync- staged sync algorithm.
Examples
-
erigon- our binary is using erigon-api with all defaults -
erigoncustom- a very simple example of adding a custom stage, a custom bucket and a custom command-line parameter -
erigon-examples - a series of examples for Erigon api
