Subject [jira] [Updated] (GORA-218) Document and set default HBase table mapping attributes
Date Sat, 27 Apr 2013 21:02:15 GMT

     [ https://issues.apache.org/jira/browse/GORA-218?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Lewis John McGibbney updated GORA-218:

    Attachment: GORA-218.patch

This is a trivial patch for trunk which merely adds in some bog standard debug logging for
hbase table mapping attributes and values. 
What I want (but admittedly don't know) is what default values are good to set within the
gora-hbase-mapping.xml used within the tests?
Can someone more HBase literate please help out here?
The idea would be to document such optional attributes somewhere and also to have them within
the test mapping file so that this can act as a resource for best sensible practice.

> Currently gora-hbase supports the following, configurable, table mapping attributes:
>           * String familyName  = fieldElement.getAttributeValue("name");
>           * String compression = fieldElement.getAttributeValue("compression");
>           * String blockCache  = fieldElement.getAttributeValue("blockCache");
>           * String blockSize   = fieldElement.getAttributeValue("blockSize");
>           * String bloomFilter = fieldElement.getAttributeValue("bloomFilter");
>           * String maxVersions = fieldElement.getAttributeValue("maxVersions");
>           * String timeToLive  = fieldElement.getAttributeValue("timeToLive");
>           * String inMemory    = fieldElement.getAttributeValue("inMemory");
> We do not make this explicit therefore we should not be surprised if no-one seems to
know about these.
> This issue should add default values for these values to all existing gora-hbase-mapping.xml
files and should also document their use, case and effect within the gora-hbase documentation.
