I uploaded about 100.000 entities into datastore and I need to execute
a type of query that shouldn't require composite indexes.
But i get this:
The built-in indices are not efficient enough for this query and your
data. Please add a composite index for this query.. An index is
missing but we are unable to tell you which one due to a bug in the
App Engine SDK
My entity has three fields (String): type, value, parent so i created
an index like this:
<datastore-indexes autoGenerate="true">
<datastore-index kind="DbAddressEntry" ancestor="false"
source="auto">
<property name="value" direction="asc" />
<property name="parent" direction="asc" />
<property name="type" direction="asc" />
</datastore-index>
</datastore-indexes>
The query uses only equality filters but sometimes only 2 params are
used (type and value, let's say)
Does that meen that i have to create another index ?
Or can something else help ?
