NAME

Metabase::Index::SimpleDB - Metabase index on Amazon SimpleDB

VERSION

version 1.000

SYNOPSIS

  require Metabase::Index::SimpleDB;
  Metabase::Index:SimpleDB->new(
    access_key_id => 'XXX',
    secret_access_key => 'XXX',
    domain     => 'metabase',
  );

DESCRIPTION

This is an implementation of the Metabase::Index and Metabase::Query roles using Amazon SimpleDB.

ATTRIBUTES

domain (required)

The SimpleDB domain to store index data in. This should be unique for each Metabase installation.

consistent

Whether consistent reads should be used. Default is 0. Probably most useful for testing.

USAGE

See Metabase::Backend::AWS for common constructor attributes and see below for constructor attributes specific to this class. See Metabase::Index, Metabase::Query and Metabase::Librarian for details on usage.

LIMITATIONS

Search queries have limitations based on the underlying SimpleDB search API. Specifically:

lexicographic comparison

All comparisons are done lexicographically, even when the field or comparison value appears to be a number.

-order

SimpleDB only supports sorting on a single attribute. Any field used for sorting must also have been included as part of a query constraint in the -where expression.

-limit

Limit is only supported when a query is sorted.
