Lars Hofhansl updated OMID-217:
-------------------------------
Description:
Playing with Omid I would like to propose two settings and one code change:
# (server) waitStrategy: LOW_CPU (without this, the TSO server will keep one
core 100% busy)
# (client) postCommitMode:
!!org.apache.omid.tso.client.OmidClientConfiguration$PostCommitMode ASYNC (the
client returns when it is safe to do so for correctness, optimizations -
updating shadow columns - happen asynchronously)
# (client) conflictDetectionLevel:
!!org.apache.omid.tso.client.OmidClientConfiguration$ConflictDetectionLevel ROW
(this is lighter than CELL)
# TSOChannelHandler.java:106 change the max packet size to 100MB, so that - if
needed - the TSO can handle large transactions (up to 20m rows). Or at least
make this a config option.
Let's discuss these...
