Prefix for functions names that implement Disque commands.
The current Disque connection.
Whether the server-client communication should be echoed to the stream specified by *ECHO-STREAM*. The default is NIL, meaning no echoing.
A stream to which the server-client communication will be echoed for debugging purposes. The default is *STANDARD-OUTPUT*.
Define and export a function with the name <*CMD-REDIX*>-<CMD> for processing a Disque command CMD. Here REPLY-TYPE is the expected reply format.
Define a specialized EXPECT method. BODY may refer to the ~ variable REPLY, which is bound to the reply received from Disque ~ server with the first character removed.
Evaluate BODY with the current connection bound to a new connection specified by the given HOST and PORT
Execute BODY inside WITH-CONNECTION. But if connection is broken due to DISQUE-CONNECTION-ERROR (a network error or timeout), transparently reopen it.
Delay execution of EXPECT’s inside BODY to the end, so that all commands are first sent to the server and then their output is received and collected into a list. So commands return :PIPELINED instead of the expected results.
Execute BODY with *CONNECTION* bound to the default Disque connection. If connection is already established, reuse it.
Close the socket of CONN.
Connect to Disque server.
Is there a current connection?
Disconnect from Disque server.
Acknowledges the execution of one or more jobs via jobs IDs. The node receiving the ACK will replicate it to multiple nodes and will try to garbage collect both the job and the ACKs from the cluster so that memory can be freed.
Adds a job to the specified queue.
Completely delete a job from a node. Note that this is similar to FASTACK, but limited to a single node since no DELJOB cluster bus message is sent to other nodes.
Remove jobs from the queue.
Queue jobs if not already queued.
Acknowledges the execution of one or more jobs via jobs IDs. The node receiving the ACK will replicate it to multiple nodes and will try to garbage collect both the job and the ACKs from the cluster so that memory can be freed.
Gets a job from the specific queue.
Returns hello format version, this node ID, all the nodes IDs, IP addresses, ports, and priority (lower is better, means node more available). Clients should use this as an handshake command when connecting with a Disque node.
JSCAN provides an interface to iterate all the existing jobs in the local node, providing a cursor in the form of an integer that is passed to the next command invocation. During the first call the cursor must be 0, in the next calls the cursor returned in the previous call is used next. The iterator guarantees to return all elements but may return duplicates.
The NACK command tells Disque to put back the job in the queue ASAP. It is very similar to ENQUEUE but it increments the job nacks counter instead of the additional-deliveries counter. The command should be used when the worker was not able to process a message and wants the message to be put back into the queue in order to be processed again.
Return, without consuming from queue, count jobs. If count is positive the specified number of jobs are returned from the oldest to the newest (in the same best-effort FIFO order as GETJOB). If count is negative the commands changes behavior and shows the count newest jobs, from the newest from the oldest.
The command provides an interface to iterate all the existing queues in the local node, providing a cursor in the form of an integer that is passed to the next command invocation. During the first call cursor must be 0, in the next calls the cursor returned in the previous call is used in the next. The iterator guarantees to return all the elements but may return duplicated elements.
Claims to be still working with the specified job, and asks Disque to postpone the next time it will deliver again the job. The next delivery is postponed for the job retry time, however the command works in a best effort way since there is no way to guarantee during failures that another node in a different network partition is performing a delivery of the same job.
Create a socket connection to the host and port of CONNECTION and set the socket of CONN to the associated socket.
Close and reopen the connection to Disque server.

Conditions of this type are signaled when errors occur
that break the connection stream. They offer a :RECONNECT restart.
Any Disque-related error.
Error reply is received from Disque server.
A list of expected results from the current pipeline.
Indicates, that commands are sent in pipelined mode.
Signal the condition of type DISQUE-CONNECTION-ERROR denoted by
the given ERROR and COMMENT offering a :RECONNECT restart to re-evaluate BODY.
When, during the execution of BODY, an error occurs that breaks the connection, a DISQUE-CONNECTION-ERROR is signalled, offering a :RECONNECT restart that will re-evaluate body after the conenction is re-established.
Acknowledges the execution of one or more jobs via jobs IDs. The node receiving the ACK will replicate it to multiple nodes and will try to garbage collect both the job and the ACKs from the cluster so that memory can be freed.
Adds a job to the specified queue.

Completely delete a job from a node. Note that this is similar to FASTACK, but limited to a single node since no DELJOB cluster bus message is sent to other nodes.
Remove jobs from the queue.
Queue jobs if not already queued.
Acknowledges the execution of one or more jobs via jobs IDs. The node receiving the ACK will replicate it to multiple nodes and will try to garbage collect both the job and the ACKs from the cluster so that memory can be freed.
Write a prefix char and a number to the stream of the current connection. If *ECHOP-P* is not NIL, write that string to *ECHO-STREAM*, too.
Write a string and CRLF-terminator to the stream of the current connection. If *ECHOP-P* is not NIL, write that string to *ECHO-STREAM*, too.
Gets a job from the specific queue.
Returns hello format version, this node ID, all the nodes IDs, IP addresses, ports, and priority (lower is better, means node more available). Clients should use this as an handshake command when connecting with a Disque node.

Describe the job.
Claims to be still working with the specified job, and asks Disque to postpone the next time it will deliver again the job. The next delivery is postponed for the job retry time, however the command works in a best effort way since there is no way to guarantee during failures that another node in a different network partition is performing a delivery of the same job.
