当我想从Cassandr读取时我有错误:
WARN 19:17:29,839 Heap is 0.8888050654459693 full.
You may need to reduce memtable and/or cache sizes.
Cassandra will now flush up to the two largest memtables to free up memory.
Adjust flush_largest_memtables_at threshold in cassandra.yaml if you don't want Cassandra to do this automatically
INFO 19:17:30,238 Unable to reduce heap usage since there are no dirty column families
当我减少flush_largest_memtables_at阈值时,没有任何变化,所以你可以帮我减少memtable或缓存大小,因为我不知道怎么做。
答案 0 :(得分:1)
在conf / cassandra-env.sh中增加MAX_HEAP_SIZE对我来说很有帮助。
