TimescaleDB allows you to copy existing chunks to a new location within a multi-node environment. This allows each data node to work both as a primary for some chunks and backup for others. If a data node fails, its chunks already exist on other nodes that can take over the responsibility of serving them.
|REGCLASS||Name of chunk to be copied|
|NAME||Data node where the chunk currently resides|
|NAME||Data node where the chunk is to be copied|
CALL timescaledb_experimental.copy_chunk(‘_timescaledb_internal._dist_hyper_1_1_chunk’, ‘data_node_2’, ‘data_node_3’);
