Dibutuhkan db-sync lebih dari 3 menit untuk mengembalikan blok fork, berikut adalah log db sync:

Ini telah terjadi selama sekitar 2 minggu, intensitasnya meningkat.

Rilis 8.0.0 akan datang (harus dirilis awal minggu depan) telah meningkatkan rollback (rollback seperti yang dilakukan di PostgreSQL tanpa Haskell melakukan pemrosesan apa pun). Saya telah melihatnya berguling dari ujung rantai, kembali ke era Byron (lebih dari satu tahun blok) dalam waktu kurang dari 10 menit.

Yang mengatakan, rollback db-sync akan selalu lebih lambat daripada rollback node.

Berikut adalah rollback dengan rollback yang ditingkatkan saat ini:

[db-sync-node:Info:50] [2021-01-23 09:49:22.66 UTC] Rolling back to slot 19829014, hash 1369c36907c449da8232ee746da9a392feeb0ad114db8ff565981922e54735c9
[db-sync-node:Info:50] [2021-01-23 09:49:22.66 UTC] Deleting slots numbered: [19829066]
[db-sync-node:Info:50] [2021-01-23 09:49:22.68 UTC] Slots deleted

Jadi menurut log, rollback terjadi dalam waktu kurang dari satu detik.

Ini diperbaiki dalam rilis 8.0.0 (mungkin hari ini).
