Goal Determine whether YugabyteDB provides a guaranteed upper bound on the time taken to elect a new tablet leader after a node failure, and how that bound is reflected in the system logs. Constraints The election timeout is a random value between raft_election_timeout_ms_min and raft_election_timeout_ms_max , configurable but not fully documented. Logs from
Goal Use YugabyteDB’s PostgreSQL‑compatible pg_stat_statements extension to surface the most expensive YSQL queries and verify whether the cost originates from local computation or distributed storage access before applying any index or flag changes. Constraints Statistics are per‑node, reset on restart, and add measurable overhead bounded by pg_stat_stateme
For a range-sharded YSQL table keyed on a monotonically increasing identifier, early write traffic concentrates on a small number of tablet leaders until tablet splitting engages. The design goal is to achieve even write distribution across nodes from table creation without incurring unnecessary per-tablet resource overhead. Two documented approaches address
Enforcing Uniform Credential Expiration Across YSQL and YCQL The goal is to implement a consistent least‑privilege policy that revokes user access automatically after a specified time, regardless of whether the client connects via YSQL (PostgreSQL‑compatible) or YCQL (Cassandra‑compatible). In YSQL, roles can be created with a VALID UNTIL timestamp, and auth
