This PR introduces a cache for GetBlobs request. The main purpose of this PR is to reduce the getBlobs latency by reading and decoding blobs from the pool in advance of the actual query. This is important especially in the context of a sparse blobpool, since it may be necessary to recover blobs from cells on a getBlobs request. Previously, the Engine API read and decoded blobs from the pool on every call. Now those calls check the cache and only fall back to the pool on a miss. The cache has two modes: - In topK mode (default), it wakes up periodically, picks the most profitable pending blob transactions up to the current fork's maxBlobsPerBlock, and loads their blobs. The selection logic is shared with the miner's block-building logic. The selection size is derived from eip4844.MaxBlobsPerBlock at the current head. - When the CL calls HasBlobs, the cache switches to hasBlobs mode and tries to pin the set it just reported as available. Cache updates (read, decode, and optionally conversion in the future) run in background goroutines. --------- Co-authored-by: Felix Lange <fjl@twurst.com> |
