RFA Java Level2 message indication of CLEAR_CACHE
As part of Level2 development our application caches and maintains the Level2 book in-memory. We noticed that sometime we get response with message indication of CLEAR_CACHE. Please clarify the following :
- Is CLEAR_CACHE only received by applications on REFRESH response or it can come as part of UPDATE response as well?
- What should we do when we receive CLEAR_CACHE indication,
1) should we clear our cache and consume the incoming message with CLEAR_CACH indication
OR
2) clear our cache and do not process the incoming message which has indication of CLEAR CACHE.
Hello @anil.kalra
According to RFA Java Developers Guide section 6.2.5 Indication Flags. CLEAR_CACHE flag is not in UPDATE response. When the application receives CLEAR_CACHE flag, the previous data should be cleared and the data in the message with CLEAR_CACHE should be cached.
Hope this help.
if the flag is set , clear cache and start building book again ,
if the flag is not set , overlay the data in refresh message on already received data.
