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.
