Decrease leveldb storage usage #1601

Open olehnikolaiev opened 1 year ago

olehnikolaiev commented 1 year ago

run the following test: add 100mb data to state - leveldb storage usage grows up to 250mb erase the data

leveldb storage usage is still ~200mb need to investigate the reason and fix it

@oleksandrSydorenkoJ to add more details and logs
