MariaDB Error 1555: Cannot Write-Lock Log Table
Description
This error occurs when an operation attempts to acquire a write lock on a table that MariaDB identifies as a 'log table'. Log tables are typically designed for append-only or read-only access, prohibiting write-locking to maintain data integrity and performance for logging purposes.
Error Message
You can't write-lock a log table. Only read access is possible
Known Causes
4 known causesExplicit Write Lock Attempt
An SQL statement, such as `LOCK TABLES log_table WRITE`, was executed on a table that is designated as a log table, which inherently only permits read access.
Table Misconfiguration
A table intended for general data storage might be mistakenly configured or perceived by MariaDB as a special log table, leading to restricted write access.
Storage Engine Restriction
The underlying storage engine might impose inherent read-only or append-only restrictions on certain table types, preventing write locks on log-like tables.
Implicit Write Operation
An operation that implicitly requires a write lock (e.g., `INSERT`, `UPDATE`, `DELETE`) was attempted on a log table, triggering the write-lock restriction.
