Introduction to replication for percolate indexes

Starting with 2.8.2 a new major feature is available - replication for percolate indexes.

The replication is based on Galera library (also used by Percona's mysql fork and MariaDB). We considered it would be better to use a tried and proven existing solution rather than inventing a bicycle and build it from the ground up which would have taken much longer.

Plain indexes replication

Manticore Search (as well as Sphinx) doesn’t yet support replication for plain or RT indexes out of the box (although we’re working on this, if you want to be a beta tester let us know at info@manticoresearch.com), so you have to implement it by yourself if you need to have a copy of your Manticore Search Read more about Plain indexes replication[…]

Free config review

There are often optimizations that can be made to a Sphinx / Manticore setup by changing some simple directives in the configuration or making quick changes to an index definition.

Some common mistakes and issues can include:

  • doing main+delta without kill-lists, even if the delta does include updated records found in the main
  • using wildcarding with very short prefix/infix which can hammer performance in some cases
  • disabled (unintentional) seamless rotates and getting stalls on index rotations
  • adding texts as string attributes even if they are not using for any kind of operation (filtering, grouping, sorting) or mandatory to be present in results
  • using deprecated settings 

Having a quick look on the configuration can show issues or potential issues, this is why we want to offer a gift to our growing community!

When uploading your configuration file, we recommend to remove any database credentials first.

We suggest also you give as many possible details about your setup: how big is the data you have, how typical queries look and what issues you experience.
