Elasticsearch's SQL jdbc driver is a fully featured JDBC driver

for Elasticsearch.

TODO add example of resolving the artifact in maven and gradle.

You can connect to it using the two APIs offered
|
2017-12-13 10:19:31 -05:00
|
|
|
by JDBC, namely `java.sql.Driver` and `DriverManager`:
|
|
|
|
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
|
|
--------------------------------------------------
|
|
|
|
include-tagged::{jdbc-tests}/JdbcIntegrationTestCase.java[connect-dm]
|
|
|
|
--------------------------------------------------
|
|
|
|
<1> The server and port on which Elasticsearch is listening for
|
|
|
|
HTTP traffic. The port is usually 9200.
|
|
|
|
<2> Properties for connecting to Elasticsearch. An empty `Properties`
|
|
|
|
instance is fine for unsecured Elasticsearch.
|
|
|
|
|
2017-12-20 13:58:32 -05:00
|
|
|
or `javax.sql.DataSource` through
|

|
|
|
["source","java",subs="attributes,callouts,macros"]

<1> The server and port on which Elasticsearch is listening for
|
|
|
|
HTTP traffic. The port is usually 9200.
|
|
|
|
<2> Properties for connecting to Elasticsearch. An empty `Properties`
|
|
|
|
instance is fine for unsecured Elasticsearch.
|
|
|
|
|
|
|
|
Which one to use? Typically client applications that provide most
|
|
|
|
configuration parameters in the URL rely on the `DriverManager`-style
|
|
|
|
while `DataSource` is preferred when being _passed_ around since it can be
|
|
|
|
configured in one place and the consumer only has to call `getConnection`
|
|
|
|
without having to worry about any other parameters.
|
|
|
|
|
|
|
|
To connect to a secured Elasticsearch server the `Properties`
|
|
|
|
should look like:
|
|
|
|
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
|
|
--------------------------------------------------
|

|
include-tagged::{security-tests}/JdbcSecurityIT.java[admin_properties]
|
|
|
|
--------------------------------------------------
|
|
|
|
|
|
|
|
Once you have the connection you can use it like any other JDBC
|
|
|
|
connection. For example:
|
|
|
|
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
