Common issues

How to reduce storage occupation

If the storage occupation of the bsc client increasing dramatically, you may consider increasing the TrieTimeout setting in config.toml.

What does TrieTimeout means?

The bsc client will keep MPT(Merkle Patricia Tree) in memory. Once the block processing time exceeds the TrieTimeout, the client will persis MPT into disk. If the client crash, it can recover from recent persisted MPT. Increasing the TrieTimeout setting will reduce storage occupation, in exchange, it will need more time to recover from a crash.

The default setting before release v1.1.1 is 100000000000, it will persist MPT about every 35 minutes.

We change the default setting to 2000000000000 in this release, it will persist MPT about every 12 hours.
