ElasticSearch to PostgreSQL Loader.

Uses es2csv, xsv, GNU sed and psql client to periodically Extract, Transform and Load data from ES to PSQL.

  • Extract: ElasticSearch is queried from the last ingestion point for new data (delta-load). The result is stored in a CSV file.
  • Transform: Currently limited to column name changes via GNU sed expressions.
  • Load: The transformed data is loaded to PostgreSQL Database using the provided schema.
