MAX_UPLOAD_SIZE

const MAX_UPLOAD_SIZE: 1065353216 = 1_065_353_216;

Defined in: packages/synapse-core/src/piece.ts:31

Maximum upload size currently supported by PDP servers.

1 GiB adjusted for fr32 expansion: 1 GiB * (127/128) = 1,065,353,216 bytes

Fr32 encoding adds 2 bits of padding per 254 bits of data, resulting in 128 bytes of padded data for every 127 bytes of raw data.

Note: While it’s technically possible to upload pieces this large as Uint8Array, streaming via AsyncIterable is strongly recommended for non-trivial sizes. See SIZE_CONSTANTS.MAX_UPLOAD_SIZE in synapse-sdk for detailed guidance.
