This filter executes a SQL query and store the result set in the fieldspecified as target
.It will cache the results locally in an LRU cache with expiry
For example you can load a row based on an id from in the event
filter { jdbc_streaming { jdbc_driver_library => "/path/to/mysql-connector-java-5.1.34-bin.jar" jdbc_driver_class => "com.mysql.jdbc.Driver" jdbc_connection_string => "jdbc:mysql://localhost:3306/mydatabase" jdbc_user => "me" jdbc_password => "secret" statement => "select * from WORLD.COUNTRY WHERE Code = :code" parameters => { "code" => "country_code"} target => "country_details" }}

5.0
The minimum number of seconds any entry should remain in the cache, defaults to 5 secondsA numeric value, you can use decimals for example { "cache_expiration" => 0.25 }
If there are transient jdbc errors the cache will store empty results for a givenparameter set and bypass the jbdc lookup, this merges the default_hash into the event, untilthe cache entry expires, then the jdbc lookup will be tried again for the same parametersConversely, while the cache contains valid results any external problem that would causejdbc errors, will not be noticed for the cache_expiration period.
500
The maximum number of cache entries are stored, defaults to 500 entriesThe least recently used entry will be evicted
{}
Define a default object to use when lookup fails to return a matching row.ensure that the key names of this object match the columns from the statement
JDBC connection string
JDBC driver class to load, for example "oracle.jdbc.OracleDriver" or "org.apache.derby.jdbc.ClientDriver"
Tentative of abstracting JDBC logic to a mixinfor potential reuse in other plugins (input/output)This method is called when someone includes this moduleAdd these methods to the base given.JDBC driver library path to third party driver library.
false
Connection pool configuration.Validate connection before use.
3600
Connection pool configuration.How often to validate a connection (in seconds)
{}
Hash of query parameter, for example { "id" => "id_field" }
Statement to execute.To use parameters, use named parameter syntax, for example "SELECT * FROM MYTABLE WHERE ID = :id"
["_jdbcstreamingdefaultsused"]
Append values to the tags
field if no record was found and default values were used
["_jdbcstreamingfailure"]
Append values to the tags
field if sql error occured
Define the target field to store the extracted result(s)Field is overwritten if exists
true
Enable or disable caching, boolean true or false, defaults to true

If this filter is successful, add any arbitrary fields to this event.Field names can be dynamic and include parts of the event using the %{field}
.
Example:
filter { jdbc_streaming { add_field => { "foo_%{somefield}" => "Hello world, from %{host}" } }}
# You can also add multiple fields at once:filter { jdbc_streaming { add_field => { "foo_%{somefield}" => "Hello world, from %{host}" "new_field" => "new_static_value" } }}
If the event has field "somefield" == "hello"
this filter, on success,would add field foo_hello
if it is present, with thevalue above and the %{host}
piece replaced with that value from theevent. The second example would also add a hardcoded field.
[]
If this filter is successful, add arbitrary tags to the event.Tags can be dynamic and include parts of the event using the %{field}
syntax.
Example:
filter { jdbc_streaming { add_tag => [ "foo_%{somefield}" ] }}
# You can also add multiple tags at once:filter { jdbc_streaming { add_tag => [ "foo_%{somefield}", "taggedy_tag"] }}
If the event has field "somefield" == "hello"
this filter, on success,would add a tag foo_hello
(and the second example would of course add a taggedy_tag
tag).
true
Disable or enable metric logging for this specific plugin instanceby default we record all the metrics we can, but you can disable metrics collectionfor a specific plugin.
Add a unique ID
to the plugin configuration. If no ID is specified, Logstash will generate one.It is strongly recommended to set this ID in your configuration. This is particularly usefulwhen you have two or more plugins of the same type, for example, if you have 2 jdbc_streaming filters.Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
filter { jdbc_streaming { id => "ABC" }}
false
Call the filter flush method at regular interval.Optional.
[]
If this filter is successful, remove arbitrary fields from this event.Example:
filter { jdbc_streaming { remove_field => [ "foo_%{somefield}" ] }}
# You can also remove multiple fields at once:filter { jdbc_streaming { remove_field => [ "foo_%{somefield}", "my_extraneous_field" ] }}
If the event has field "somefield" == "hello"
this filter, on success,would remove the field with name foo_hello
if it is present. The secondexample would remove an additional, non-dynamic field.
[]
If this filter is successful, remove arbitrary tags from the event.Tags can be dynamic and include parts of the event using the %{field}
syntax.
Example:
filter { jdbc_streaming { remove_tag => [ "foo_%{somefield}" ] }}
# You can also remove multiple tags at once:filter { jdbc_streaming { remove_tag => [ "foo_%{somefield}", "sad_unwanted_tag"] }}
If the event has field "somefield" == "hello"
this filter, on success,would remove the tag foo_hello
if it is present. The second examplewould remove a sad, unwanted tag as well.
