-
-Avatica also supports [Protocol Buffers](https://developers.google.com/protocol-buffers/)
-as a message format since version 1.5.0. The Protocol Buffer, or protobuf for
-short, implementation is extremely similar to the JSON implementation. Some
-differences include protobuf's expanded type support (such as native byte arrays)
-and inability to differentiate between the default value for a field and the
-absence of a value for a field.
-
-Other notable structural differences to JSON include the addition of a
-`WireMessage` message which is used to identify the type of the wrapped message
-returned by the server (synonymous with `request` or `response` attribute on the
-JSON messages) and a change to `TypedValue` containing an `Object` value to
-a collection of optional strongly-typed values (as protobuf does not natively
-support an `Object` type that is unwrapped at runtime).
-
-Unless otherwise specified with use of the `required` modifier, all fields in
-all protocol buffer messages are `optional` by default.

-
-Security is an important topic between clients and the Avatica server. Most JDBC
-drivers and databases implement some level of authentication and authorization
-for limit what actions clients are allowed to perform.
-
-Similarly, Avatica must limit what users are allowed to connect and interact
-with the server. Avatica must primarily deal with authentication while authorization
-is deferred to the underlying database. By default, Avatica provides no authentication.
-Avatica does have the ability to perform client authentication using Kerberos,
-HTTP Basic, and HTTP Digest.
-
-The authentication and authorization provided by Avatica are designed for use
-*instead* of the authentication and authorization provided by the underlying database.
-The typical `user` and `password` JDBC properties are **always** passed through to
-the Avatica server which will cause the server to enforce those credentials. As such,
-Avatica's authentication types mentioned here only have relevance when the underlying database's authentication
-and authorization features are not used. (The Kerberos/SPNEGO integration is one difference as the impersonation feature
-is specifically designed to allow the Kerberos identity to be passed to the database -
-new advanced implementations could also follow this same approach if desired).
-

-<ul>
-  {% for item in page.auth_types %}<li><a href="#{{ item.anchor }}">{{ item.name }}</a></li>{% endfor %}
-</ul>
-
-
-## HTTP Basic Authentication
-
-Avatica supports authentication over [HTTP Basic](https://en.wikipedia.org/wiki/Basic_access_authentication).
-This is simple username-password based authentication which is ultimately insecure when
-operating over an untrusted network. Basic authentication is only secure when the transport
-is encrypted (e.g. TLS) as the credentials are passed in the clear. This authentication is
-supplementary to the provided JDBC authentication. If credentials are passed to the database
-already, this authentication is unnecessary.
-
-### Enabling Basic Authentication
-
-{% highlight java %}
-String propertiesFile = "/path/to/jetty-users.properties";
-// All roles allowed
-String[] allowedRoles = new String[]  {"*"};
-// Only specific roles are allowed
-allowedRoles = new String[] { "users", "admins" };
-HttpServer server = new HttpServer.Builder()
-    .withPort(8765)
-    .withHandler(new LocalService(), Driver.Serialization.PROTOBUF)
-    .withBasicAuthentication(propertiesFile, allowedRoles)
-    .build();
-{% endhighlight %}
-
-The properties file must be in a form consumable by Jetty. Each line in this
-file is of the form: `username: password[,rolename ...]`
-
-For example:
-
-{% highlight properties %}
-bob: b0b5pA55w0rd,users
-steve: 5teve5pA55w0rd,users
-alice: Al1cepA55w0rd,admins
-{% endhighlight %}
-
-Passwords can also be obfuscated as MD5 hashes or oneway cryptography ("CRYPT").
-For more information, see the [official Jetty documentation](http://www.eclipse.org/jetty/documentation/current/configuring-security-secure-passwords.html).
-
-## HTTP Digest Authentication
-
-Avatica also supports [HTTP Digest](https://en.wikipedia.org/wiki/Digest_access_authentication).
-This is desirable for Avatica as it does not require the use of TLS to secure communication
-between the Avatica client and server. It is configured very similarly to HTTP Basic
-authentication. This authentication is supplementary to the provided JDBC authentication.
-If credentials are passed to the database already, this authentication is unnecessary.
-
-### Enabling Digest Authentication
-
-{% highlight java %}
-String propertiesFile = "/path/to/jetty-users.properties";
-// All roles allowed
-String[] allowedRoles = new String[]  {"*"};
-// Only specific roles are allowed
-allowedRoles = new String[] { "users", "admins" };
-HttpServer server = new HttpServer.Builder()
-    .withPort(8765)
-    .withHandler(new LocalService(), Driver.Serialization.PROTOBUF)
-    .withDigestAuthentication(propertiesFile, allowedRoles)
-    .build();
-{% endhighlight %}
-
-The properties file must be in a form consumable by Jetty. Each line in this
-file is of the form: `username: password[,rolename ...]`
-
-For example:
-
-{% highlight properties %}
-bob: b0b5pA55w0rd,users
-steve: 5teve5pA55w0rd,users
-alice: Al1cepA55w0rd,admins
-{% endhighlight %}
-
-Passwords can also be obfuscated as MD5 hashes or oneway cryptography ("CRYPT").
-For more information, see the [official Jetty documentation](http://www.eclipse.org/jetty/documentation/current/configuring-security-secure-passwords.html).
-
-## Kerberos with SPNEGO Authentication
-
-Because Avatica operates over an HTTP interface, the simple and protected GSSAPI
-negotiation mechanism ([SPNEGO](https://en.wikipedia.org/wiki/SPNEGO)) is a logical
-choice. This mechanism makes use of the "HTTP Negotiate" authentication extension to
-communicate with the Kerberos Key Distribution Center (KDC) to authenticate a client.
-
-### Enabling SPNEGO/Kerberos Authentication in servers
-
-The Avatica server can operate either by performing the login using
-a JAAS configuration file or login programmatically. By default, authenticated clients
-will have queries executed as the Avatica server's kerberos user. [Impersonation](#impersonation)
-is the feature which enables actions to be run in the server as the actual end-user.
-
-As a note, it is required that the Kerberos principal in use by the Avatica server
-**must** have an primary of `HTTP` (where Kerberos principals are of the form
-`primary[/instance]@REALM`). This is specified by [RFC-4559](https://tools.ietf.org/html/rfc4559).
-
-#### Programmatic Login
-
-This approach requires no external file configurations and only requires a
-keytab file for the principal.
-
-{% highlight java %}
-HttpServer server = new HttpServer.Builder()
-    .withPort(8765)

-    .build();

-
-#### JAAS Configuration File Login
-
-A JAAS configuration file can be set via the system property `java.security.auth.login.config`.
-The user must set this property when launching their Java application invoking the Avatica server.
-The presence of this file will automatically perform login as necessary in the first use
-of the Avatica server. The invocation is nearly the same as the programmatic login.
-
-{% highlight java %}
-HttpServer server = new HttpServer.Builder()
-    .withPort(8765)
-    .withHandler(new LocalService(), Driver.Serialization.PROTOBUF)
-    .withSpnego("HTTP/host.domain.com@DOMAIN.COM")
-    .build();
-{% endhighlight %}
-
-The contents of the JAAS configuration file are very specific:
-
-{% highlight java %}
-com.sun.security.jgss.accept  {
-  com.sun.security.auth.module.Krb5LoginModule required
-  storeKey=true
-  useKeyTab=true
-  keyTab=/etc/security/keytabs/avatica.spnego.keyTab
-  principal=HTTP/host.domain.com@DOMAIN.COM;
-};
-{% endhighlight %}
-
-Ensure the `keyTab` and `principal` attributes are set correctly for your system.
-
-### Impersonation
-
-Impersonation is a feature of the Avatica server which allows the Avatica clients
-to execute the server-side calls (e.g. the underlying JDBC calls). Because the details
-on what it means to execute such an operation are dependent on the actual system, a
-callback is exposed for downstream integrators to implement.
-
-For example, the following is an example for creating an Apache Hadoop `UserGroupInformation`
-"proxy user". This example takes a `UserGroupInformation` object representing the Avatica server's
-identity, creates a "proxy user" with the client's username, and performs the action as that
-client but using the server's identity.
-
-{% highlight java %}
-public class PhoenixDoAsCallback implements DoAsRemoteUserCallback {
-  private final UserGroupInformation serverUgi;
-
-  public PhoenixDoAsCallback(UserGroupInformation serverUgi) {
-    this.serverUgi = Objects.requireNonNull(serverUgi);
-  }
-
-  @Override
-  public <T> T doAsRemoteUser(String remoteUserName, String remoteAddress, final Callable<T> action) throws Exception {
-    // Proxy this user on top of the server's user (the real user)
-    UserGroupInformation proxyUser = UserGroupInformation.createProxyUser(remoteUserName, serverUgi);
-
-    // Check if this user is allowed to be impersonated.
-    // Will throw AuthorizationException if the impersonation as this user is not allowed
-    ProxyUsers.authorize(proxyUser, remoteAddress);
-
-    // Execute the actual call as this proxy user
-    return proxyUser.doAs(new PrivilegedExceptionAction<T>() {
-      @Override
-      public T run() throws Exception {
-        return action.call();
-      }
-    });
-  }
-}
-{% endhighlight %}
-
-## Client implementation
-
-Many HTTP client libraries, such as [Apache Commons HttpComponents](https://hc.apache.org/), already have
-support for performing Basic, Digest, and SPNEGO authentication. When in doubt, refer to one of
-these implementations as it is likely correct.
-
-### SPNEGO
-
-For information on building SPNEGO support by hand, consult [RFC-4559](https://tools.ietf.org/html/rfc4559)
-which describes how the authentication handshake, through use of the "WWW-authenticate=Negotiate"
-HTTP header, is used to authenticate a client.
-
-### Password-based
-
-For both HTTP Basic and Digest authentication, the [avatica_user]({{site.baseurl}}/docs/client_reference.html#avatica-user)
-and [avatica_password]({{site.baseurl}}/docs/client_reference.html#avatica-password)
-properties are used to identify the client with the server. If the underlying database
-(the JDBC driver inside the Avatica server) require their own user and password combination,
-these are set via the traditional "user" and "password" properties in the Avatica
-JDBC driver. This also implies that adding HTTP-level authentication in Avatica is likely
-superfluous.

-This marks the separation of Avatica from its previous location as a sub-module
-of Apache Calcite's Maven build.
-
-This separation is not to remove Avatica from
-the governance of the Apache Calcite project, but to allow for even more rapid
-releases from both the Avatica and Calcite projects. We can confidently make new
-releases of each without having to worry about the current state of development
-features in the other.

-Apache Calcite's PMC has just released Avatica 1.7.1, the first
-release of [Avatica](http://calcite.apache.org/avatica/) as an
-independent project. We're excited because it makes Avatica easier to
-use, and allows us to be more agile in our release schedule.
-
-(Avatica was previously released as part of Calcite. Avatica is still
-governed by Apache Calcite's PMC, and stored in the same git
-repository as Calcite, but releases are no longer synchronized, and
-Avatica does not depend on any Calcite modules.)
-
-A significant portion of the work of this release was "Maven work" to
-separate the build and release processes, but there were several
-important bug fixes, including a security fix for Jetty (see below).
-
-Performance, specifically on the write path, was a big focus in this
-release.
-[[CALCITE-1091](https://issues.apache.org/jira/browse/CALCITE-1091)]
-contained a number of important changes. Some of these changes (e.g.
-[[CALCITE-1092](https://issues.apache.org/jira/browse/CALCITE-1092)]
-and
-[[CALCITE-1093](https://issues.apache.org/jira/browse/CALCITE-1093)])
-were related to heap usage in the Avatica server, while
-[[CALCITE-1094](https://issues.apache.org/jira/browse/CALCITE-1094)]
-and
-[[CALCITE-1117](https://issues.apache.org/jira/browse/CALCITE-1117)]
-were strictly performance-related.
-
-The latter improved performance the most. Switching to the
-[Apache Commons HttpComponents Client](http://hc.apache.org/)
-library instead of using the Java platform's built-in
-[HttpURLConnection](https://docs.oracle.com/javase/7/docs/api/java/net/HttpURLConnection.html),
-we noticed a 15% improvement in pure write workloads.
-
-Three dependent library upgrades:
-
-* We completely removed
-  [Commons Logging](https://commons.apache.org/proper/commons-logging/)
-  in favor of [SLF4J](http://slf4j.org/) in
-  [[CALCITE-669](https://issues.apache.org/jira/browse/CALCITE-669)].
-  This logging framework update will allow downstream integrators to
-  use the logging implementation of their choice instead of being
-  forced to inherit Commons Logging.
-* We upgraded Jackson from 2.1.1 to 2.6.3 in
-  [[CALCITE-1021](https://issues.apache.org/jira/browse/CALCITE-1021)].
-* We upgraded Jetty from 9.2.7.v20150116 to 9.2.15.v20160210 in
-  [[CALCITE-1156](https://issues.apache.org/jira/browse/CALCITE-1156)]
-  to fix a
-  [security issue](https://blog.gdssecurity.com/labs/2015/2/25/jetleak-vulnerability-remote-leakage-of-shared-buffers-in-je.html).
-
-Note that Avatica's Maven coordinates have changed. The `groupId` is
-now "org.apache.calcite.avatica" (previously "org.apache.calcite"),
-and `artifactId`s are
-"avatica",
-"avatica-metrics",
-"avatica-metrics-dropwizardmetrics3",
-"avatica-noop-driver",
-"avatica-server"
-(previously "calcite-avatica", etc.). Make sure to update these when
-upgrading to this version.
