Method Detail

withConnectionConfiguration

public SolrIO.Write withConnectionConfiguration(SolrIO.ConnectionConfiguration connectionConfiguration)

Provide the Solr connection configuration object.

to

public SolrIO.Write to(java.lang.String collection)

Provide name of collection while reading from Solr.

Parameters:

collection - the collection toward which the requests will be issued

withMaxBatchSize

public SolrIO.Write withMaxBatchSize(int batchSize)

Provide a maximum size in number of documents for the batch. Depending on the execution engine, size of bundles may vary, this sets the maximum size. Change this if you need to have smaller batch. Default max batch size is 1000.

Parameters:

batchSize - maximum batch size in number of documents

withRetryConfiguration

public SolrIO.Write withRetryConfiguration(SolrIO.RetryConfiguration retryConfiguration)

Provides configuration to retry a failed batch call to Solr. A batch is considered as failed if the underlying CloudSolrClient surfaces HttpSolrClient.RemoteSolrException, SolrServerException or IOException. Users should consider that retrying might compound the underlying problem which caused the initial failure. Users should also be aware that once retrying is exhausted the error is surfaced to the runner which may then opt to retry the current partition in entirety or abort if the max number of retries of the runner is completed. Retrying uses an exponential backoff algorithm, with minimum backoff of 5 seconds and then surfacing the error once the maximum number of retries or maximum configuration duration is exceeded.

Example use:

 SolrIO.write()
   .withRetryConfiguration(SolrIO.RetryConfiguration.create(10, Duration.standardMinutes(3))
   ...
 

Parameters:

retryConfiguration - the rules which govern the retry behavior

Returns:

the SolrIO.Write with retrying configured
