Size-Capped Memory Tables with Configuration Settings

Why it matters

This feature introduces memory and row caps for <code>Memory</code> tables through the new settings <code>min_bytes_to_keep</code>, <code>max_bytes_to_keep</code>, <code>min_rows_to_keep</code>, and <code>max_rows_to_keep</code>. It helps manage resource consumption by controlling how much data is retained in memory tables, preventing unbounded growth and potential memory exhaustion.

How to use it

To enable size limits on <code>Memory</code> tables, configure the table-specific or global settings <code>min_bytes_to_keep</code>, <code>max_bytes_to_keep</code>, <code>min_rows_to_keep</code>, and <code>max_rows_to_keep</code>. These settings define minimum and maximum thresholds for memory size and row count, allowing you to fine-tune retention according to your workload requirements.
