# Clickhouse

# Why migrating the database to Clickhouse?

  • The significant increase in reports loading (from 10 to 20 times faster).
  • Less disk usage.

# Changes in the API

  • Column ip contains both IPv4 and IPv6 values.
  • Columns click_id and conversion_id contain UUID value instead of number (integer).
  • Column visitor_id is removed, but you can still use visitor_code .
