Project: The database is overwhelmingly write-driven (high-volume API request and ping logging). Years of growth and over-long retention have left it expensive to store and slow to query. Two issues dominate cost: a -4 TB request-log table whose space cannot be reclaimed by DELETE (InnoDB does not return it; OPTIMIZE TABLE would lock the table for an unpredictable time), and a high IOPS bill from running the write-heavy cluster on Aurora standard pricing. Required Skills: DBA with MySQL / Aurora MySQL (InnoDB) Knowledge of MySQL RANGE partitioning Percona toolkit AWS Aurora Node.js / GoLang (beneficial) This will be a 4 week contract, with the intended approach already known (can be provided), so requires an expert to validate this, harden it and execute it. If interested, please apply or contact Matt Randall ((url removed)) for more information. Spectrum IT Recr... Contract
