Modifying Market Data Schema

The schema that represents the market data in the RAPCache database significantly affects message-loading performance.

Sybase recommends that, while you are designing the market data schema, you:
  • Use round-robin partitioning to partition the database table that stores the market data because the RAPCache subscriber can load data concurrently into multiple partitions.
  • Have a small number of indexes for the table storing market data, because a large number of indexes adversely affects message load performance.
