The Parquet Summarizer Executor is able to process the content of a Parquet file and extract each of the rows and the table schema. Each extracted row will be processed by the summarizers attached to the job.
The Parquet Summarizer Executor allows to download the content of the file into a local temporary file to reduce memory usage.
Rows Filtering
The Parquet Summarizer Executor has the option to configure a groovy script to filter which rows will be processed.
Example:
// This script must return a boolean. // The references of the job, doc, component, row and table objects are available. // Javadoc references // Row (row) - http://{manager}/javadocs/com/accenture/aspire/services/summarization/Row.html // Table (table) - http://{manager}/javadocs/com/accenture/aspire/services/summarization/Table.html row.getBoolean("sensitive") == true
