Metadata synchronization in a distrubuted database

A system, comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• lock, by a second node, a partition in the second node responsive to a partition utility command executed by a utility node and affecting the partition handled by the utility node, and responsive to a query received at the second node, wherein the utility node and the second node are part of a cluster;
• block, by the second node, the query to a data portion of the partition in the second node responsive to the partition utility command;
• lock, by the second node, object metadata of the second node based on a cluster-wide lock issued responsive to the partition utility command;
• receive, by the second node, changes to object metadata of the utility node and applying the changes to the object metadata of the second node;
• and
• unlock, by the second node, the partition and the object metadata of the second node and unblock the query, once the changes to the object metadata of the utility node are applied to the object metadata of the second node.

A non-transitory computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:

• locking, by a second node, a partition in the second node responsive to a partition utility command executed by a utility node and affecting the partition handled by the utility node and responsive to a query received at the second node, wherein the utility node and the second node are part of a cluster;
• blocking, by the second node, the query to a data portion of the partition in the second node responsive to the partition utility command;
• locking, by the second node, object metadata of the second node based on a cluster-wide lock issued responsive to the partition utility command;
• receiving, by the second node, changes to object metadata of the utility node and applying the changes to the object metadata of the second node;
• and
• unlocking, by the second node, the partition and the object metadata of the second node and unblocking the query, once the changes to the object metadata of the utility node are applied to the object metadata of the second node.
