#GET ADVANCED CALL RECORDER TO REINDEX UPDATE#

You don’t need to deploy if you reindex only in order to update the data in the index but not its structure.

#GET ADVANCED CALL RECORDER TO REINDEX CODE#

If it changes, you must deploy your new code as soon as the live-reindex finishes. the structure of your index may or may not change after the reindexing and so the code. There are 2 different aspects that must be considered when live-reindexing: The live-reindex feature is very easy to use, but reindexing while the indices may change is a tricky process, so you must understand the basics about how it works in order to use it properly, or you might corrupt your indices (see Important Warnings). The reindex_models and the reindex_active_models methods require the elastics-models gem (if you use elastics-rails it is automatically required). If you are on any other OS, read redis installation.

#GET ADVANCED CALL RECORDER TO REINDEX INSTALL#

If you are on a Mac you can install redis with homebrew: You need to install redis and the redis gem, and/or you may need to add it to your Gemfile. The live-reindex feature rely on a redis list in order to track the changes made by the processes of your running app during the reindex. Personal Note: Live-reindexing is tricky per se, but finding a way to perform it easily and regardless the app structure has been an even trickier challenge. Simpler cases work the same way, with the only exception that you may skip some setting not needed for your particular context. In this page we consider the most complex case: code and (changing) index to swap. In all cases, live-reindex provides a smooth reindexing with all the features you need, like index renaming/aliasing, hot-swap, no down-time, etc.

When you actually don’t have any index in your app yet, for example when you start a new app.

When you don’t change the code nor the structure of your index, but you need to reindex, for example when you crawl another site and index its content.

When your app is not changing the index while you are reindexing, for example when your index/indices are updated only periodically.

Live-reindex is also very useful in a few of other simpler cases, for example: Just a few lines of code to write, practically no down-time, no index inconsistency so no code failures and a very smooth user experience. When the new index is complete, the hot-swap of the old code and index with the new code and index can take place. During the rebuild, all the changes made by the old code (still running live) get tracked and mirrored on the new index. You can leave your production app running the old code/index (and keep updating the old index) while the live-reindex rebuilds a new index by using your new code. The elastics live-reindex feature is what you need in this case. The “deploy-then-update” will not be better than the “update-then-deploy” technique: both will likely produce a quite bad user experience during the process - depending on the magnitude of your changes. Your index will stay in an inconsistent state during the time of the update, and that may probably cause both your old and new code to fail during the process. From a commercial point of view, that solution is probably better than shutting down the site, but it is still a bad one from a technical point of view. re-import the data while the old data is still in place.

If your app is making money, shutting it down would likely cost you a lot of bucks. But quite typically your index/indices are big, so the reindexing would require you to shut down your site (or part of it) during a few hours, and that wouldn’t be acceptable. Maybe you have the old code running live and constantly updating the old index/indices, and you need to deploy some new search feature with the new code, that would produce and need a new index, so what should you do? If the production index/indices are small, you may shut-down your site for a few minutes in order to deploy the new code, reindex and restart the site. If you ever tried to reindex your production app while it is running you know that it might be a quite difficult task. Live-reindexing is the process to re-build one or more indices that are used and eventually updated in real-time by a production application, without any appreciable application down-time.
