Add new field type in managed-schema
<fieldType name="dealsRedis" keyField="id"
redisKey="deals:vehicles:cars"
defVal="0"
stored="true"
indexed="true"
class="com.argakon.solr.RedisField"
valType="float"
host="127.0.0.1"
port="6379"
password="password"
scanCount="3000"
dataType="z" />Add new listeners in solrconfig.xml for cache heat. On big collections can take a long time :(.
<!-- Redis external data reloader -->
<listener event="newSearcher" class="com.argakon.solr.RedisFieldReloader"/>
<listener event="firstSearcher" class="com.argakon.solr.RedisFieldReloader"/>If you want to use RedisField values in bq you can add this:
<valueSourceParser name="deals" class="com.argakon.solr.RedisValueSourceParser">
<str name="host">127.0.0.1</str>
<str name="port">6379</str>
<str name="password">password</str>
<str name="timeout">60000</str>
<str name="scanCount">1000</str>
<str name="dataType">z</str>
<str name="redisKey">deals</str>
<str name="defVal">0</str>
</valueSourceParser>After that simply add deals() to bf
