Add planned-reparent command to pscale branch vtctld#1240
Merged
Conversation
Adds `pscale branch vtctld planned-reparent` with two subcommands:
- `create` — initiates a planned reparent shard operation, waits for
completion by default (--wait=false to return immediately)
- `get` — polls the status of an existing operation
Usage:
pscale branch vtctld planned-reparent create <db> <branch> \
--keyspace <ks> --shard <shard> --new-primary <alias>
Updates planetscale-go to v0.159.0 for PlannedReparentShardService.

Instead of create/get subcommands, use a single command with two modes:
# Execute a planned reparent
pscale branch vtctld planned-reparent-shard <db> <branch> \
--keyspace <ks> --shard <shard> --new-primary <alias>
# Check on an existing operation
pscale branch vtctld planned-reparent-shard <db> <branch> --id <op-id>
This matches how Vitess exposes PlannedReparentShard as a single action
rather than a CRUD resource.
The root command runs the reparent (all flags required, no ambiguity):
pscale branch vtctld planned-reparent-shard <db> <branch> \
--keyspace <ks> --shard <shard> --new-primary <alias>
A status subcommand checks on an existing operation:
pscale branch vtctld planned-reparent-shard status <db> <branch> <op-id>
