DETACH LEAF

Detaches a leaf.

Similar to REMOVE LEAF except that it keeps the leaf in the detached state instead of removing it entirely.

Syntax

DETACH LEAF 'host':port

Remarks

  • DETACH LEAF transitions the leaf from the online state to the detached state.

  • DETACH LEAF is useful if you would like to temporarily take down a leaf for repairs without erasing it from metadata.

  • Use ATTACH LEAF to attach a leaf that is currently in a detached state.

  • This command causes implicit commits. See COMMIT for more information.

  • Node Requirements for SingleStore Commands

  • See the Permission Matrix for the required permission.

Example

DETACH LEAF '192.168.1.110':3306;

DETACH LEAVES

Detaches all leaves.

Similar to REMOVE LEAVES, except it detaches all leaves instead of removing them.

Syntax

DETACH LEAVES ('host_1':port_1, ..., 'host_n':port_n)

Remarks

  • DETACH LEAVES transitions the leaves from an online state to a detached state.

  • Use ATTACH LEAF ALL to attach leaves that are in a detached state.

  • All leaves must be in the same availability group to DETACH LEAVES.

  • DETACH LEAVES is an all-or-nothing command: either all the leaves will be detached, or none of them will.

Example

DETACH LEAVES ('192.168.1.110':8080, '192.168.1.111':8080, '192.168.1.112':8080);
