Subject [jira] [Updated] (BLUR-431) Auto-Save/Load Block-cache
Date Mon, 18 May 2015 11:54:59 GMT

     [ https://issues.apache.org/jira/browse/BLUR-431?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravikumar updated BLUR-431:
---------------------------
    Attachment: CacheIOContext.java
                CacheDirectory.java
                CacheFileUtil.java
                AutoSavingBaseCache.java
                BlockCacheIndexWarmup.java

I am attaching a re-worked second version…

1. blockIds are streamed to an already opened cache-file. First-cut pre-sort and then write
blockIds approach is removed
2. Warmup will read blockIds from the cache-file, form a bit-set and then scan the file in
ascending/sequential order
3. These blockIds are read via lucene-APIs. Underlying CacheDirectory will take care of re-populating
the block-cache
