ANN: Couchbase Mobile 1.2 is released!

[Jens Alfke]

We’ve just released Couchbase Mobile 1.2, a significant upgrade to each of the components. Here’s the official blog post. As always, you can download it here.* Or if you want to build yourself, check out the release/1.2.0 branch of any repo.

Of course there are zillions of improvements and fixes, but the big items are:

• Sync Gateway manageability features, like the ability to take buckets offline and to purge obsolete documents.
• Sync Gateway Accelerator, an optional service that greatly increases scaleability of multiple SG nodes.
• The faster ForestDB storage engine is now available on all platforms of Couchbase Lite, and has been improved (automatic background compaction, better full-text search, etc.)
• Database encryption (using AES-256) is now available on all platforms of Couchbase Lite, for both storage engines, and we include a build of SQLCipher to make it easier to build your app with SQLite encryption.

For more details you can peruse the release notes of Sync Gateway, CBL iOS/Mac/tvOS, CBL Java/Android, CBL .NET.

Huge thanks to those of you who worked with prerelease code from the master branch, and submitted bug reports or even contributed patches! You helped make this a better release and we’re grateful.

—Jens

* CocoaPods users: We’ll have an updated podspec ready ASAP.

Is there any documentation on Sync Gateway Accelerator?

Hey Todd,

The docs on sg_accel are still pending, but we're looking to have them pushed up in the next week or so.

In the meantime we have some rough notes here:

https://github.com/couchbase/sync_gateway/wiki/Sync-Gateway-1.2-Changes

Also, anything specific you are looking for?  Are you looking to find out how to use it, how it works, or both?

Any update about document of Sync Gateway Accelerator?

[James Nocentini]

Preview docs for SG Accel are at https://github.com/couchbase/sync_gateway/wiki/Introduction-to-Sync-Gateway-Accelerator

[atom992]

Thank you. some questions:

The architecture  of My project looks like as following:

CBLite  <--> SG

                       ^

                       |

                       v

                      Web

How should I configure CBLite side and Web side for add SG Accel Cluster?

As I understand, SG Accel Cluster offer write node, and SG Cluster offer read node,

so CBLite read data from SG,and write data to SG Accel;

Web read data from SG,and write data to SG Accel;

Am I right?

For CBLite, when I need pull  data from SG, I need post /_replicate as following

```

{

    "headers": {

              "Cookie":"SyncGatewaySession=287d228958b5d02c3dd652900cd74035a830165c"

          },

    "source": {

          "headers": {

              "Cookie":"SyncGatewaySession=287d228958b5d02c3dd652900cd74035a830165c"

          },

          "url":"http://SG_Cluster:4984/sgdb/"

    },

    "target" : "cbldb",

    "continuous" : true

}

```

when I need push  data to SG, I need post /_replicate as following

```

{

    "headers": {

              "Cookie":"SyncGatewaySession=287d228958b5d02c3dd652900cd74035a830165c"

          },

    "source":"cbldb" ,

    "target" : {

          "headers": {

              "Cookie":"SyncGatewaySession=287d228958b5d02c3dd652900cd74035a830165c"

          },

          "url":"http://SG_Accel_Cluster:4984/sgdb/"

    },

    "continuous" : true

}

```

And for Web, When I need read data from SG, I need get data from

```

http://SG_Cluster:4984/sgdb/<someDocs>

```

And when I need write data to SG,I need post data to

```

http://SG_Accel_Cluster:4984/sgdb/<someDocs>?rev=<some_rev> -d"<some json data>"

```

And Can I deploy SG_Accel_Node And SG_Node on the same mathine?

[atom992]

I am download sg_accel for MAC from http://packages.couchbase.com/releases/couchbase-sync-gateway/1.3.1/couchbase-sg-accel-enterprise_1.3.1-16_x86_64.tar.gz

but there is no sg_accel commend,and the file size is the same as couchbase-sync-gateway/bin/sync_gateway 

the size is 24017612.

@atom992 All web traffic should still be directed at the Sync Gateway node.  The sg_accel node moves the server mutation listener and channel caching work out of the individual Sync Gateway nodes - clients should be communicating with the sync_gateway node in the way they always have.

It looks like there's a packaging problem for Mac sg_accel - looking into that now.

[atom992]

It still the same 

http://packages.couchbase.com/releases/couchbase-sync-gateway/1.3.1/couchbase-sg-accel-enterprise_1.3.1-16_x86_64.tar.gz

[ad...@couchbase.com]

That's been updated now - it should have the correct version available from the download page now.  Thanks for pointing that out.

[atom992]

ok it works now.Thank you.
