This version includes some database changes, so on first start the BlockSummary table will need to be rebuilt. This will take some time (maybe an hour) and do a lot of IO. After this, the database compaction will be run and the size will return to normal. If you run out of storage during this process, the easy thing to do is either remove the database directory (pointed to by db_path) and resync or increase the volume size.
For sharding, if not specified each node will follow shard 0 and all shards under shard 0, which is all shards. So for now, no configuration changes need to be made.
Nodes need to be updated to 2.0.0 by block 211600 which is estimated to be mid May 2022.
This version changes the expected parameters for the pool from node_host and node_port to node_uri which can contain a list of nodes. Examples:
node_uri=grpc+tls://localhost
node_uri=grpc://localhost
node_url=node_uri=grpc+tls://snow-a.1209k.com,grpc+tls://snow-b.1209k.com
If multiple nodes are listed, it is not treated as a fail-over, it is treated as all-active. MrPlow will ask each one to build a block template and will use the most profitable (in terms of SNOW per hash). This is so when eventually there are different nodes tracking different shards MrPlow can aggregate the options to allow miners to mine on any shard.
Mining pools need to be updated to 2.0.0 by block 211600 which is estimated to be mid May 2022.
