commit 0044dfc04efc3553de8c5bd3375692a0444ff2b4
Author: Karsten Loesing <karsten.loesing at gmx.net>
Date: Tue Aug 28 09:40:12 2018 +0200
Reduce database size and variance of query response times.
The changes in this commit are mainly driven by the following database
changes:
- Fingerprints are no longer stored repeatedly as strings in the
statusentry and exitlistentry tables but instead moved to their own
fingerprint table and referenced by identifier. This is a step
towards normalization that ideally reduces database size a lot by
itself.
- The statusentry table no longer contains the raw status entry but
instead only those parts that are required for searching and
displaying results. This includes nickname and exit information,
where the former is not stored as string but as reference into its
own nickname table.
- There is a new table specifically for lookups which returns all
relevant fingerprint identifiers for a date and an IP address
prefix. The new search function based on this new table performs as
little table joining as necessary and leaves some of the filtering
and joining to the servlet.
More details can be found in the exonerator2.sql file, which also
serves as migration script from the existing schema to the new one.
Implements #27356.
