Query interceptor

Abstract

Query Interceptor is a product comprising three components which aims to maintain healthy database by restricting bad queries from hitting the database and restrict user access to only permitted data. It intercepts queries before hitting the database, identifies queries that are bad for cluster health, sanitizes those queries and applies security filters on queries to ensure authorized access to the database. Apart from this, Query Interceptor also gives information about queries like aliases, subqueries, tables, columns, joins, table count and join count.
