The "DataImportHandler" page has been changed by JamesDyer: http://wiki.apache.org/solr/DataImportHandler?action=diff&rev1=325&rev2=326 Comment: SOLR-4051: Configurable DIH Property Writers * This operation will be started in a new thread and the ''status'' attribute in the response should be shown ''busy'' now. * The operation may take some time depending on size of dataset. - * When full-import command is executed, it stores the start time of the operation in a file located at ''conf/dataimport.properties'' + * When full-import command is executed, it stores the start time of the operation in a file located at ''conf/dataimport.properties'' ([[#Configuring The Property Writer|this file is configurable]]) * This stored timestamp is used when a delta-import operation is executed. * Queries to Solr are not blocked during full-imports. * It takes in extra parameters: @@ -345, +345 @@ {{{ deltaQuery="SELECT MAX(did) AS did FROM ${dataimporter.request.dataView}" }}} + + = Configuring The Property Writer = + <!> [[Solr4.1]] + Add the tag 'propertyWriter' directly under the 'dataConfig' tag. The property "last_index_time" is converted to text and stored in the properties file and is available for the next import as the variable '${dih.last_index_time}' . This tag gives control over how this properties file is written. + + {{{ + <propertyWriter dateFormat="yyyy-MM-dd HH:mm:ss" type="SimplePropertiesWriter" directory="data" filename="my_dih.properties" locale="en_US" /> + }}} + * This tag is optional, resulting in the default locale,directory and filename. The 'type' will default to SimplePropertiesWriter for non-SolrCloud installations. For SolrCloud, ZKPropertiesWriter is default. + * 'type' - the implementation class. This is required unless <propertyWriter /> is omitted entirely. + * 'filename' - (SimplePropertiesWriter) The default is the name of the request handler followed by ".properties", for instance, dataimport.properties + * 'directory' -(SimplePropertiesWriter) The default is "conf". + * 'dateFormat' - (SimplePropertiesWriter/ZKPropertiesWriter) Specify a java.text.SimpleDateFormat pattern to use when converting the date to text. The default is yyyy-MM-dd HH:mm:ss . For JDBC escape syntax, use {'ts' ''yyyy-MM-dd HH:mm:ss''} . + * 'locale' - (SimplePropertiesWriter/ZKPropertiesWriter) In Solr 4.1, The default locale is the ROOT Locale. This differs from Solr 4.0 and prior, which always used the machine's default locale. = Usage with XML/HTTP Datasource = DataImportHandler can be used to index data from HTTP based data sources. This includes using indexing from REST/XML APIs as well as from RSS/ATOM Feeds.
