Manticore Software 3.2.0. relese

New features

Storage for full-text fields. It is now possible not only to index texts but also store them and retrieve their content in results.

Document storage can be enabled with index directive stored_fields by providing a list of full-text fields that should be stored.

By default storage compress the content saved on the disk. Fine-tuning of the compression can be done with new directives docstore_block_size, docstore_compression, and docstore_compression_level. Another fine-tuning setting is docstore_cache_size, which declares the size of the memory cache used when reading and unpacking the stored content.

As this is an experimental feature, there are currently several known issues:

  • retrieving results from an index with docstore experience a performance hit compared with results from the same index without docstore. In the case of remote distributed indexes, there is a high impact on network traffic, CPU and memory on master and low performance.
  • for distributed indexes explicit SELECT must be used -  SELECT id, field1, field2 etc.

These issues will be addressed in future releases.

Improvements and changes

HTTP API SSL feature has been improved, both in the performance and support of different algorithms.

Non-cjk built-in charset table improved.

Disabled logging for UPDATE and DELETE statements a SELECT entry in the query log.

Starting with this release, official packages for RHEL / CentOS 8 are provided. The packages can be downloaded from GitHub or installed using our official yum repository.

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.
