Migrate to 1.3.0

Upgrading from Atoti Market Data 1.2.0 - See Atoti Market Data 1.3.0 Release Notes.

Summary

  • Upgrade to Atoti Server 6.1.4: Atoti Market Data has been upgraded to Atoti Server 6.1.4.
  • DirectQuery cache: This release adds support for a DirectQuery cache that is being beta-tested in Atoti Market Risk.

Breaking changes

  • The IDefaultMarketDataRetriever interface extends the new ISingleTable interface which has a single method to return the name of the table that the retriever reads from. You will need to implement this method if you implement this interface unless you are extending the SingleTableMarketDataRetriever class that provides a default implementation.
  • AMarketDataPostProcessor now extends ACachePrefillPostProcessor instead of ABasicPostProcessor. This has one abstract method getCacheSlice that is used for the new DirectQuery cache. It is implemented in ADirectQueryCachingMarketDataPostProcessor but if you do not extend from this class you can just return null.

DirectQuery Cache

This release contains code to support a new caching mechanism designed to optimize the retrieval of market data in a DirectQuery application. This is a beta feature of Atoti Market Risk and is only expected to be used in this context. These changes have minimal impact on projects that are not using the cache or not using DirectQuery. Breaking changes are detailed above.

To support this change new classes have been added in the package com.activeviam.marketdata.lib.internal. It is recommended not to use these classes directly as they are subject to change and removal with later releases.
