WangChao commented on IOTDB-674:
--------------------------------
Now the partition may has timeseries whose schema not in local.When need, it
will pull from remote node, but only cache it, not register in local. So when
startup, it colud not found meta.
Maybe we need a local meta cache, and all timeseries schema should store in all
nodes.
Or
only remote meta cache should be serilized to file, when startup, replay wal
could get meta from this remote cache file.
IMO, second solution maybe more better.
> [Distributed] WAL cannot be replayed due to meta missing

> Project: Apache IoTDB
> Issue Type: Bug
> Components: Core/Cluster
> Reporter: Tian Jiang
> Assignee: WangChao
> Priority: Major
> Labels: cluster, distributed
>
> Some replaying of PhysicalPlans like insertion need metadata to proceed but
> in the distributed version the metadata may not exist on that node so the
> replaying will fail.
> Moreover, since the replaying is in the start-up phase, it is not likely for
> the node to pull metadata from other nodes as it is not in the cluster yet.
