Vijay updated CASSANDRA-946:
----------------------------
Attachment: 946-Load_Data_v001.txt
946-Add_Config_v001.txt
Attached is a quick way to load all the data into the cache without changing
anything in the existing code base.... I was thinking of having a tunable
parameter which will say how many days of data i want to load to cache... I was
thinking of adding code in column family which will tell the timestamp of the
latest update to a column and if it is later than the configured value then
load to cache.... else skip.... Comments/Suggestions?
> Add a configuration and implementation to populate the data into memory

> Proactively load data into the memory when the node is started, there will be
> a configuration to enable this function and will be per Columnfamily. The
> requirement is to speed up the reads for data which can reside 100% of in the
> memory.... In addition to enabling the RowCache to 100% we can do this so as
> upgrades or any other means of restart will not clear the cache in the server.
