Hello, We’ve added a streaming standby on a gcp container. There’s a lot of network latency between our primary in EU and this standby in South America. I did a big update on a table ( 4 millions rows) and it generates a lot of lag : more than 5 hours. The standby has great hardware ressources: cpu, ssd disk and had no load during this update. How could we handle this lag and have less impact, less lag ? Basic PG Config: shared_buffers = 8GB work_mem = 128MB max_connections = 600 wal_keep_segments = 1000 wal_sender_timeout = 0 replication_timeout=(not set) wal_receiver_status_interval=10s max_wal_senders=20 Checkpoint_timeout = 10min Max_wal_size= 2GB min_wal_size= 1GB Thank you Mai |
