This is controlled via \texttt{tserver.wal.blocksize}. A basic recommendation is that when \texttt{tserver.walog.max.size} is larger than 2GB in size, set \texttt{tserver.wal.blocksize} -to 2GB. +to 2GB. Increasing the block size to a value larger than 2GB can result in decreased write +performance to the write-ahead log file which will slow ingest. \subsection{Cluster Specification}
