Readyset is a MySQL and Postgres wire-compatible caching layer that sits in front of existing databases to speed up queries and horizontally scale read throughput. Under the hood, ReadySet caches the results of cached select statements and incrementally updates these results over time as the underlying data changes.
mysql_async has a "statement cache" feature, which limits the number of
prepared statements that exist on a given connection at one time. This
is enabled by default with a value of 32. When the number of prepared
statement exceeds 32, a previously-created prepared statement is
deallocated, which results in errors when a client attempts to execute
it.
This commit disables this statement cache to ensure that we can support
an arbitrary number of prepared statements (as we do for Postgres).
Release-Note-Core: Fixed an issue where the number of prepared
statements for a MySQL connection was limited to 32
