DESCRIPTION
VMOD using the synchronous hiredis library API to access Redis servers from VCL.
VOID subnets(STRING masks="")
Arguments
subnets:
Comma-delimited list of weights + subnet masks used to select among servers associated to a
database instance when executing commands. Order is relevant. Only IPv4 addresses are
supported. If not provided, value in the VMOD_REDIS_SUBNETS environment variable will be
used.
This is useful in setups using Redis instances deployed across multiple data centers or
availability zones.
Description
Using this function is not mandatory. If used, it must be called during vcl_init before creating
any database instance. If a database instance has already been created calls to this function are
silently ignored.
VOID sentinels(STRING locations, INT period, INT connection_timeout, INT command_timeout, ENUM protocol, BOOL
tls, STRING tls_cafile, STRING tls_capath, STRING tls_certfile, STRING tls_keyfile, STRING tls_sni,
STRING password)
VOID sentinels(
STRING locations="",
INT period=60,
INT connection_timeout=500,
INT command_timeout=0,
ENUM {RESP2, RESP3, default} protocol=default,
BOOL tls=0,
STRING tls_cafile="",
STRING tls_capath="",
STRING tls_certfile="",
STRING tls_keyfile="",
STRING tls_sni="",
STRING password=""
)
Arguments
locations:
Comma-delimited list of Redis Sentinel servers. Only host (IP or DNS name) + port format is
allowed. If not provided, value in the VMOD_REDIS_SENTINELS environment variable will be
used.
This is useful in setups using non-clustered Redis instances in order to (1) keep roles
(i.e. master / slave) updated; and (2) decrease priority of unreachable servers when
creating execution plans. This is not designed for auto-discovery of Redis Servers.
period: how frequently (seconds) Redis Sentinel periodical checks are executed (0 means disabling
periodical checks). Beware (1) proactive checks are also executed anytime the VCL state is changed
to warm; and (2) Sentinel Pub/Sub events are listened and processed even when periodical checks
are disabled.
connection_timeout: connection timeout (milliseconds; 0 means no timeout) to the Redis Sentinel
servers.
command_timeout: command timeout (milliseconds; 0 means no timeout) when executing Redis Sentinel
commands.
protocol: protocol to be used when talking to Redis Sentinel servers. Beware switching from RESP2
to RESP3 is only possible since Redis 6.0 and it uses an additional HELLO command when creating
new Redis Sentinel connections. Be careful RESP3 support is only available since hiredis 0.15.0.
tsl: if enabled, TLS will be used when establishing connections.
tls_cafile: if not empty, this CA certificate file will be used to verify TLS connections.
tls_capath: if not empty, this will be the directory storing trusted CA certificates used to
verify TLS connections. If neither tls_cafile nor tls_capath are specified, the default
system-wide trusted root certs configuration will apply.
tls_certfile: if not empty, this certificate file will be used to authenticate TLS connections.
tls_keyfile: if not empty, this private key file will be used to authenticate TLS connections.
tls_sni: if not empty, this server name indication (i.e. SNI) will be used when establishing TLS
connections.
password: if not empty, requests for authentication using the AUTH command will be submitted when
creating new Redis Sentinel connections. This password will be used for all Redis Sentinel
servers.
Description
Using this function is not mandatory.

new xdb = redis.db(
STRING location="",
ENUM {master, slave, auto, cluster} type=auto,
INT connection_timeout=1000,
INT connection_ttl=0,
INT command_timeout=0,
INT max_command_retries=0,

BOOL tls=0,

STRING tls_keyfile="",
STRING tls_sni="",
STRING user="",
STRING password="",
INT sickness_ttl=60,
BOOL ignore_slaves=0,
INT max_cluster_hops=32
)
Arguments
location: Redis connection string. Both host (IP or DNS name) + port and UNIX sockets are
supported. Only the IP + port format is allowed when Redis Cluster support is enabled. Do not use
DNS names in combination with ``redis.subnets()`` or ``redis.sentinels()``.
type: type of the Redis server referenced by location:
• The auto value enables automatic discovery of the current role of the server on bootstrap time
using the ROLE command.
• The cluster value enables Redis Cluster support, automatically discovering other servers in the
cluster and their roles on demand using the CLUSTER SLOTS command.
connection_timeout: connection timeout (milliseconds; 0 means no timeout) to the Redis server.
connection_ttl: TTL (seconds) of Redis connections (0 means no TTL). Once the TTL of a connection
is consumed, the module transparently reestablishes it. See "Client timeouts" in
http://redis.io/topics/clients for extra information.
command_timeout: command timeout (milliseconds; 0 means no timeout) when executing a Redis
command. It can be overridden during command execution with .timeout().
max_command_retries: number of retries to be executed after a failed command execution. It can be
overridden during command execution with .retries().
shared_connections: if enabled, Redis connections are not local to Varnish worker threads, but
shared by all threads using one or more pools.
max_connections:
When shared_connections is enabled, the VMOD creates one pool of Redis connections per
location and database instance. This option sets the maximum number of connections in each
pool. All Varnish worker threads using the same database instance will share connections in
these pools. Pools are not shared between database instances.
Note that when Redis Cluster support is enabled for a database, each server is the cluster
is internally labeled by the VMOD with its location (IP + port).
When shared_connections is disabled, Redis connections are local to each Varnish worker
thread. This option sets the maximum number of Redis connections per Varnish worker thread.
Each thread keeps up to one connection per location and database instance. If more than one
(database, location) pair is available, incrementing this limit allows recycling of Redis
connections.
WARNING: when creating multiple database instances, always use the same value in all
instances using private connections. Otherwise you may experience inconsistent behavior.
protocol: protocol to be used when talking to Redis Server servers. Beware switching from RESP2 to
RESP3 is only possible since Redis 6.0 and it affects to type conversion rules. Be careful RESP3
support is only available since hiredis 0.15.0.
tsl: if enabled, TLS will be used when establishing connections.
tls_cafile: if not empty, this CA certificate file will be used to verify TLS connections.
tls_capath: if not empty, this will be the directory storing trusted CA certificates used to
verify TLS connections. If neither tls_cafile nor tls_capath are specified, the default
system-wide trusted root certs configuration will apply.
tls_certfile: if not empty, this certificate file will be used to authenticate TLS connections.
tls_keyfile: if not empty, this private key file will be used to authenticate TLS connections.
tls_sni: if not empty, this server name indication (i.e. SNI) will be used when establishing TLS
connections.
user: if not empty and a password is provided, requests for authentication using the AUTH or HELLO
command will include both the user name and its password. That enables usage of the Redis ACL
system, available since Redis 6.0.
password: if not empty, requests for authentication using the AUTH or HELLO command will be
submitted when creating new Redis connections. This password will be used for all Redis servers,
including discovered servers when Redis Cluster support is enabled.
sickness_ttl: TTL (seconds) of the sickness flag (0 means no sickness flags) associated to a Redis
server. Once a server is flagged as sick and while the flag is not expired the module will lazily
drop existing connections to that server and it will try to avoid it as much as possible when
creating execution plans. This TTL is overridden when Redis Sentinel servers are configured and
some Sentinel discovers an unreachable server.
ignore_slaves: if enabled, slave servers are not considered when executing commands. In other
words, enabling this option implicitly forces master == true when using the .execute() method.
max_cluster_hops: maximum number of redirections (0 means no limit) when executing a command and
Redis Cluster support has been enabled.
Description
Creates a new database instance.
VOID xdb.add_server(STRING location, ENUM type)
VOID xdb.add_server(
STRING location,
ENUM {master, slave, auto, cluster} type
)
Arguments
location: Redis connection string. Both host (IP or DNS name) + port and UNIX sockets are
supported. If Redis Cluster support has been enabled only the IP + port format is allowed. Do not
use DNS names in combination with ``redis.subnets()`` or ``redis.sentinels()``.
type: type of the Redis server referenced by location:
• The auto value enables automatic discovery of the current role of the server on bootstrap time
using the ROLE command.
• If Redis Cluster support has been enabled cluster is the only allowed value.
Description
Adds an extra Redis server.
If Redis Cluster support has been enabled other servers in the cluster and their roles are
automatically discovered by the VMOD using the CLUSTER SLOTS command. In any case, knowing more
cluster servers during startup increases the chances of discover the cluster topology if some
server is failing.
VOID xdb.command(STRING name)
Arguments
name: name of the Redis command to be executed.
Description
Enqueues a Redis command (only the name of the command) for further execution. Arguments should be
enqueued separately calling one or more times to the .push() method.
On execution time, EVAL commands are internally replace by EVALSHA commands, which fallback to the
original EVAL command if the Redis server returns a NOSCRIPT error (see
http://redis.io/commands/eval).
VOID xdb.timeout(INT command_timeout)
Arguments
command_timeout: command timeout (milliseconds; 0 means no timeout) to be used when executing a
specific Redis command.
Description
Allows overriding the default command timeout provided when calling .db().
VOID xdb.retries(INT max_command_retries)
Arguments
max_command_retries: number of retries to be executed after a failed command execution.
Description
Allows overriding the default number of retries provided when calling .db().
VOID xdb.push(STRING arg)
Arguments
arg: argument of a previously enqueued Redis command.
Description
Provides an argument to a previously enqueued Redis command.
VOID xdb.execute(BOOL master=1)
Arguments
master: when enabled slave servers are not considered for execution.
Return value
VOID
Description
Executes a previously enqueued Redis command.
When more than one Redis server is available, the destination server is selected according with
master and with the list of weights + subnet masks provided when calling redis.subnets().
WARNING: allowing execution of commands in slave servers (i.e. master == false) must be carefully
used:
• When Redis Cluster support is disabled, sending a read-write command to a read-only slave server
will result in an error reply.
• It's safe to send read-only LUA scripts using EVAL or EVALSHA commands to a read-only slave
server when Redis Cluster support is disabled. Being a read-only slave server does not block
writes in the script cache.
• When Redis Cluster support is enabled, sending a read-write command to a slave server will
result in a redirection to the right master server. This kind of redirections trigger an
internal rediscovery of the cluster topology. The client side won't notice the redirection, but
triggering such an expensive operation on every command is a terrible idea.
• It's not safe to send read-only LUA scripts using ``EVAL`` or ``EVALSHA`` commands to a slave
server when Redis Cluster support is enabled. Redis Cluster handles EVAL and EVALSHA1 command as
write operations that must be redirected to a master server. Therefore, this would result on a
rediscovery of the cluster topology on every command execution. The VMOD internally forces
master == true when Redis Cluster support is enabled and EVAL or EVALSHA command are submitted
in order to avoid this counterintuitive scenario.
