Market Data Schema

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

When you design the market data schema, Sybase recommends thatyou 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.
  • A small number of indexes for the table storing market data, because a large number of indexes adversely affects message-load performance.
