pub enum ClientContext<BI> {
Disk,
InMemory(BI),
}Expand description
Backend type for the execution client.
The process of executing a block has been decoupled from the block import pipeline. There are two kinds of clients for executing the block:
-
Client using the disk backend. This is the default behaviour in Substrate. The state is maintained in the disk backend and pruned according to the parameters provided on startup.
-
Client using the in memory backend. This is specifically designated for fast block execution in the initial full sync stage, the in memory backend keeps the entire latest chain state in the memory for executing blocks, the previous states are not stored. The block executor using the in memory backend needs to import the block within the executor to update the in memory chain state.
