How Can We Create Znodes?

Answer»

Create a znode with the given PATH. The flag argument specifies whether the created znode will be ephemeral, persistent, or sequential. By default, all znodes are persistent.

  • Ephemeral znodes (flag: E) will be automatically DELETED when a session expires or when the client disconnects.
  • Sequential znodes guaranty that the znode path will be unique.
  • ZooKeeper ENSEMBLE will add sequence number along with 10 digit padding to the znode path. For example, the znode path /myapp will be converted to /myapp0000000001 and the next sequence number will be /myapp0000000002.

If no flags are specified, then the znode is considered as persistent.

create /path /data

To create a Sequential znode, add -s flag as shown below.

create -s /path /data

To create an Ephemeral Znode, add -e flag as shown below.

create -e /path /data
