<!-- If you enable the `min_bytes_to_use_mmap_io` setting,
|
|
the data in MergeTree tables can be read with mmap to avoid copying from kernel to userspace.
|
|
It makes sense only for large files and helps only if data reside in page cache.
|
|
To avoid frequent open/mmap/munmap/close calls (which are very expensive due to consequent page faults)
|
|
and to reuse mappings from several threads and queries,
|
|
the cache of mapped files is maintained. Its size is the number of mapped regions (usually equal to the number of mapped files).
|
|
The amount of data in mapped files can be monitored
|
|
in system.metrics, system.metric_log by the MMappedFiles, MMappedFileBytes metrics
|
|
and in system.asynchronous_metrics, system.asynchronous_metrics_log by the MMapCacheCells metric,

and also in system.events, system.processes, system.query_log, system.query_thread_log by the
|
|
CreatedReadBufferMMap, CreatedReadBufferMMapFailed, MMappedFileCacheHits, MMappedFileCacheMisses events.
|
|
Note that the amount of data in mapped files does not consume memory directly and is not accounted
|
|
in query or server memory usage - because this memory can be discarded similar to OS page cache.
|
|
The cache is dropped (the files are closed) automatically on removal of old parts in MergeTree,
|
|
also it can be dropped manually by the SYSTEM DROP MMAP CACHE query.

Parameters:
|
|
host - LDAP server hostname or IP, this parameter is mandatory and cannot be empty.
|
|
port - LDAP server port, default is 636 if enable_tls is set to true, 389 otherwise.
|
|
bind_dn - template used to construct the DN to bind to.
|
|
The resulting DN will be constructed by replacing all '{user_name}' substrings of the template with the actual
|
|
user name during each authentication attempt.
|
|
user_dn_detection - section with LDAP search parameters for detecting the actual user DN of the bound user.
|
|
This is mainly used in search filters for further role mapping when the server is Active Directory. The
|
|
resulting user DN will be used when replacing '{user_dn}' substrings wherever they are allowed. By default,
|
|
user DN is set equal to bind DN, but once search is performed, it will be updated with to the actual detected
|
|
user DN value.
|
|
base_dn - template used to construct the base DN for the LDAP search.
|
|
The resulting DN will be constructed by replacing all '{user_name}' and '{bind_dn}' substrings
|
|
of the template with the actual user name and bind DN during the LDAP search.
|
|
scope - scope of the LDAP search.
|
|
Accepted values are: 'base', 'one_level', 'children', 'subtree' (the default).
|
|
search_filter - template used to construct the search filter for the LDAP search.
|
|
The resulting filter will be constructed by replacing all '{user_name}', '{bind_dn}', and '{base_dn}'
|
|
substrings of the template with the actual user name, bind DN, and base DN during the LDAP search.
|
|
Note, that the special characters must be escaped properly in XML.
|
|
verification_cooldown - a period of time, in seconds, after a successful bind attempt, during which a user will be assumed
|
|
to be successfully authenticated for all consecutive requests without contacting the LDAP server.
|
|
Specify 0 (the default) to disable caching and force contacting the LDAP server for each authentication request.
|
|
enable_tls - flag to trigger use of secure connection to the LDAP server.
|
|
Specify 'no' for plain text (ldap://) protocol (not recommended).
|
|
Specify 'yes' for LDAP over SSL/TLS (ldaps://) protocol (recommended, the default).
|
|
Specify 'starttls' for legacy StartTLS protocol (plain text (ldap://) protocol, upgraded to TLS).
|
|
tls_minimum_protocol_version - the minimum protocol version of SSL/TLS.
|
|
Accepted values are: 'ssl2', 'ssl3', 'tls1.0', 'tls1.1', 'tls1.2' (the default).
|
|
tls_require_cert - SSL/TLS peer certificate verification behavior.
|
|
Accepted values are: 'never', 'allow', 'try', 'demand' (the default).
|
|
tls_cert_file - path to certificate file.
|
|
tls_key_file - path to certificate key file.
|
|
tls_ca_cert_file - path to CA certificate file.
|
|
tls_ca_cert_dir - path to the directory containing CA certificates.
|
|
tls_cipher_suite - allowed cipher suite (in OpenSSL notation).

<!-- To enable Kerberos authentication support for HTTP requests (GSS-SPNEGO), for those users who are explicitly configured
|
|
to authenticate via Kerberos, define a single 'kerberos' section here.
|
|
Parameters:
|
|
principal - canonical service principal name, that will be acquired and used when accepting security contexts.
|
|
This parameter is optional, if omitted, the default principal will be used.
|
|
This parameter cannot be specified together with 'realm' parameter.
|
|
realm - a realm, that will be used to restrict authentication to only those requests whose initiator's realm matches it.
|
|
This parameter is optional, if omitted, no additional filtering by realm will be applied.
|
|
This parameter cannot be specified together with 'principal' parameter.
|
|
Example:
|
|
<kerberos />
|
|
Example:
|
|
<kerberos>
|
|
<principal>HTTP/clickhouse.example.com@EXAMPLE.COM</principal>

<!-- To add an LDAP server as a remote user directory of users that are not defined locally, define a single 'ldap' section
|
|
with the following parameters:
|
|
server - one of LDAP server names defined in 'ldap_servers' config section above.
|
|
This parameter is mandatory and cannot be empty.
|
|
roles - section with a list of locally defined roles that will be assigned to each user retrieved from the LDAP server.
|
|
If no roles are specified here or assigned during role mapping (below), user will not be able to perform any
|
|
actions after authentication.
|
|
role_mapping - section with LDAP search parameters and mapping rules.
|
|
When a user authenticates, while still bound to LDAP, an LDAP search is performed using search_filter and the
|
|
name of the logged in user. For each entry found during that search, the value of the specified attribute is
|
|
extracted. For each attribute value that has the specified prefix, the prefix is removed, and the rest of the
|
|
value becomes the name of a local role defined in ClickHouse, which is expected to be created beforehand by
|
|
CREATE ROLE command.
|
|
There can be multiple 'role_mapping' sections defined inside the same 'ldap' section. All of them will be
|
|
applied.
|
|
base_dn - template used to construct the base DN for the LDAP search.
|
|
The resulting DN will be constructed by replacing all '{user_name}', '{bind_dn}', and '{user_dn}'
|
|
substrings of the template with the actual user name, bind DN, and user DN during each LDAP search.
|
|
scope - scope of the LDAP search.
|
|
Accepted values are: 'base', 'one_level', 'children', 'subtree' (the default).
|
|
search_filter - template used to construct the search filter for the LDAP search.
|
|
The resulting filter will be constructed by replacing all '{user_name}', '{bind_dn}', '{user_dn}', and
|
|
'{base_dn}' substrings of the template with the actual user name, bind DN, user DN, and base DN during
|
|
each LDAP search.
|
|
Note, that the special characters must be escaped properly in XML.
|
|
attribute - attribute name whose values will be returned by the LDAP search. 'cn', by default.
|
|
prefix - prefix, that will be expected to be in front of each string in the original list of strings returned by
|
|
the LDAP search. Prefix will be removed from the original strings and resulting strings will be treated
|
|
as local role names. Empty, by default.
|
|
Example:
|
|
<ldap>
|
|
<server>my_ldap_server</server>
|
|
<roles>
|
|
<my_local_role1 />
|
|
<my_local_role2 />
|
|
</roles>
|
|
<role_mapping>
|
|
<base_dn>ou=groups,dc=example,dc=com</base_dn>
|
|
<scope>subtree</scope>
|
|
<search_filter>(&(objectClass=groupOfNames)(member={bind_dn}))</search_filter>
|
|
<attribute>cn</attribute>
|
|
<prefix>clickhouse_</prefix>
|
|
</role_mapping>
|
|
</ldap>
|
|

|
|
<ldap>
|
|
<server>my_ad_server</server>
|
|
<role_mapping>
|

Right now the protocol is pretty simple and it only takes into account:

- cluster name

- query

Also it will be nice if the following will be implemented:
|
|
- source hostname (see interserver_http_host), but then it will depends from DNS,
|
|
it can use IP address instead, but then the you need to get correct on the initiator node.
|
|
- target hostname / ip address (same notes as for source hostname)

- time-based security tokens
