Usage
Adjust threadpool size and control concurrency
Please see the crypto-async module for advice on adjusting threadpool size and controlling concurrency.
Encoding Parity Shards
1var ReedSolomon = require('@ronomon/reed-solomon'); 2 3// Specify the number of data shards (<= ReedSolomon.MAX_K): 4var k = 6; 5 6// Specify the number of parity shards (<= ReedSolomon.MAX_M): 7var m = 3; // Protect against the loss of any 3 data or parity shards. 8 9// Create an encoding context (can be cached and re-used concurrently): 10var context = ReedSolomon.create(k, m); 11 12// Specify the size of each shard in bytes (must be a multiple of 8 bytes): 13var shardSize = 65536; 14 15// Allocate the data buffer containing all data shards: 16var buffer = Buffer.alloc(shardSize * k); 17 18// Specify the offset into the data buffer at which data shards begin: 19// This allows you to include a header. 20var bufferOffset = 0; 21 22// Specify the size after this offset of all data shards: 23// This allows you to include a footer. 24var bufferSize = shardSize * k; 25 26// Allocate the parity buffer containing all parity shards: 27var parity = Buffer.alloc(shardSize * m); 28 29// Specify the offset into the parity buffer at which parity shards begin: 30// This allows you to include a header. 31var parityOffset = 0; 32 33// Specify the size after this offset of all parity shards: 34// This allows you to include a footer. 35var paritySize = shardSize * m; 36 37// Specify the sources, present in buffer or parity (as bit flags): 38// We are encoding parity shards, so we mark all data shards as sources. 39var sources = 0; 40for (var i = 0; i < k; i++) sources |= (1 << i); 41 42// Specify the targets, missing in buffer or parity, which should be encoded: 43// We are encoding parity shards, so we mark all parity shards as targets: 44var targets = 0; 45for (var i = k; i < k + m; i++) targets |= (1 << i); 46 47// Encode all parity shards: 48ReedSolomon.encode( 49 context, 50 sources, 51 targets, 52 buffer, 53 bufferOffset, 54 bufferSize, 55 parity, 56 parityOffset, 57 paritySize, 58 function(error) { 59 if (error) throw error; 60 // Parity shards now contain parity data. 61 } 62);
Encoding Corrupted Shards
