We are using leveldb version 1.20. Ours is a java application which will do put and delete batch operations towards leveldb via jni. in one of our servers we have seen that manifest file size has been increased to 25GB. Can we know reason for this increase. Also if we execute repair db will our application be crashed due to large Manifest size. Do our application store that manifest file in memory and process the rdb operation? Or do we have any other impacts like extra RAM consumption when we execute rdb?
Please find below the settings of our leveldb and repair db:
#Bloom filter policy bit count for db
#Bloom filter policy bit count for repair db
Also whenever we restart our JVM, we will open a close the existing db and reopen new db. During that time if manifest file size is huge, Our the RSS of our application in top command is keep on growing and at one point application is crashing due to no physical memory. Why the entire Manifest file is getting loaded? Even though we have configured the Cache size as 3GB, why our RSS increasing beyond 10GB and application is crashing
