Hi All, I am upgrading my elastic-search from elasticsearch-0.90.0.RC2 to elasticsearch-0.90.5. As default file compound format is false so files should be stored as normal files like .fdx,.fdt and many other formats. This is expected behaviour which i was getting in elasticsearch-0.90.0.RC2. But elasticsearch-0.90.5 storing the data as compound format. I tried to disable compound file storage by defining "_index.compound\_format: false_" in config file but it is giving the same behaviour. When i set "_index.refresh\_interval: 1_" in config file then it started storing the data as normal. After restarting elastic-search it again convert the data as compound format. Any suggestion how to disable compound file storage format ? -- _Thanks & Regards_ _Hanish Bansal_ -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Newly flushed segments are will be written into the compound format regards less of the `compound_format` setting. This setting applies on when segments get merged into bigger segments. In general means that only small segments will have the compound file format. What is the reason why you don't want compound segments? The idea behind compound file format is to reduce the number of open file descriptors to a Lucene index (shard). Since segments get flushed all the time due to frequent refresh (1 second by default), there can be some compound segments.

> [@Hanish\_Bansal](#): > > index.compound\_format I think you can use these two properties: index: compound\_format: false compound\_on\_flush: false As the result you will get 6 files for newly created segments. Without these properties it would be 2 files: segname.scf and segname.si. P.S. 2 years have been passed 😉 ---
