While there is plenty of well-documented benefits to using a connection pooler, there are some arguments to be made against using one: Introducing a middleware in the communication inevitably introduces some latency. A middleware becomes a single point of failure. Should You Use a PostgreSQL Connection Pooler?

This may help tune your table level autovacuum settings appropriately. Tuning Autovacuum in PostgreSQL. How do we identify the tables that need their autovacuum settings tuned ? . In order to tune autovacuum for tables individually, you must know the number of inserts/deletes/updates on a table for an interval.

If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls. Our engineering teams tuned their services for performance after factoring in increased resource utilization due to tracing.

However, this strategy does not work for all databases. Passive instances across regions are also possible, though it is recommended to operate in the same region as the database host in order to keep the change capture latencies low. In the latter case, write traffic is blocked until the dump completes. Figure 4— Delta Connector.

Finally, not inlining resources has an added latency cost because the file needs to be requested. As such, a micro-optimization is, again, how you probably need to fine-tune things on a low level to really benefit from it. There is no need to change your bundling or inlining strategy, nor to consolidate or shard your server farm.
