… with future data:

  • Add best practices and planning recommendations to schema_and_data_layout: my best guess here, based on existing documentation
  • Add risks and technical details to truncate-shard command: based on Dan's description influxdata/DAR/issues/534
  • Add cautions to rebalance guide that link to more details

Closes influxdata/DAR/issues/534

I'm probably going to dial this back, based on Dan's request.

I'm not sure I'm liking the 'truncating hot shards' references; it sort of implies that there's a 'truncating cold shards', doesn't it? Is it just me?

Yeah, it sort of does. I'll copy the command description into the rebalance doc and change it to "truncating shards".
