示例1: getDescriptor
// getDescriptor implements the DescriptorAccessor interface.
func (p *planner) getDescriptor(plainKey sqlbase.DescriptorKey, descriptor sqlbase.DescriptorProto,
) (bool, error) {
gr, err := p.txn.Get(plainKey.Key())
if err != nil {
return false, err
}
if !gr.Exists() {
return false, nil
}
descKey := sqlbase.MakeDescMetadataKey(sqlbase.ID(gr.ValueInt()))
desc := &sqlbase.Descriptor{}
if err := p.txn.GetProto(descKey, desc); err != nil {
return false, err
}
switch t := descriptor.(type) {
case *sqlbase.TableDescriptor:
table := desc.GetTable()
table.MaybeUpgradeFormatVersion()
// TODO(dan): Write the upgraded TableDescriptor back to kv. This will break
// the ability to use a previous version of cockroach with the on-disk data,
// but it's worth it to avoid having to do the upgrade every time the
// descriptor is fetched. Our current test for this enforces compatibility
// backward and forward, so that'll have to be extended before this is done.
