Currently, I am fetching all liquidity-related data from Raydium API. (https://api.raydium.io/v2/sdk/liquidity/mainnet.json)
And then matching with my desired token address to filter the right PoolKeys. But this process is taking too much time.

First of all, a newbie in Solana development speaking.

I want to study the leadership schedule switch between multiple nodes in a local cluster of test validators. Is this even possible? Solana noob – pardon my ignorance.
