Motivation

Description

  • call getBlobsV2 once per slot, triggered by the first seen beacon_block or data_column_sidecar gossip message
  • preallocate buffers for getBlobsV2, consume the new fromHexInto() api in feat: fromHexInto() api #8275
    • only do it for gossip messages at the current clock slot to make it safe
  • enhance results of getDataColumnsFromExecution() and track in metrics

Closes #8281
Closes #8271

Test on fusaka-devnet-3

  • testing in progress as it takes time for a node to be synced

the only change in this file is to remove getDataColumnsFromExecution call, but it caused a lot of diffs due to indentation

  • memory and gc was decreased significantly
Screenshot 2025-08-28 at 20 22 25
  • all getBlobsV2 calls use the preallocated buffer
Screenshot 2025-08-28 at 20 23 38
  • getBlobsV2 result - need to investigate why there are failed calls later:
Screenshot 2025-08-28 at 20 25 21
  • getBlobsV2 time was improved, I think we don't see a lot of improvements because most of it is traffic time

call getBlobsV2 once per slot, triggered by the first seen beacon_block or data_column_sidecar gossip message

agree with this, the effectiveness of getBlobsV2 will be questionable anyways on mainnet due to private blob transactions and once we increase blob count further it seems likely that columns disseminate faster through the network than blobs on the EL side
