Use ›cache‹ in "flow monitor-map".

---snip---
flow exporter-map flow-export

 transport udp 1111
 source Loopback0
 destination 192.168.0.1
!
flow monitor-map flow-mon-ipv4
 record ipv4
 exporter flow-export
 cache entries 50000
 cache timeout active 15

!
sampler-map flow1024
 random 1 ouf-of 1024
!
interface te0/0/0/0
 flow ipv4 monitor netflow-monitor sampler flow1024 ingress
 flow ipv4 monitor netflow-monitor sampler flow1024 egress

You can find documentation about that topic in "Cisco IOS XR Netflow 
Configuration Guide for the Cisco CRS Router".
