Error processing table path with regex

Error message

Error processing table path with regex: {}

What it means

Logged by JdbcCatalogUtils.processRegexTablePath when matching a configured table path against its regex fails or the matched groups cannot be processed — the regex-style table name in the JDBC source config is the input at fault.

Solutions

Inspect the chained SQLException cause logged with the warning
Verify connectivity and credentials to the database used for metadata queries
Confirm the JDBC dialect/plugin supports the database and its metadata queries
Retry if the cause is transient, or remove the failing regex path from table config

Defensive patterns

Strategy: try-catch

Validate before calling

// Confirm connectivity and metadata access before job submission
try (Connection c = DriverManager.getConnection(url, user, pass)) {
    c.getMetaData().getTables(); // throws early if metadata queries fail
}

Try / catch

try {
    List<CatalogTable> tables = JdbcCatalogUtils.getTables(...);
} catch (SQLException e) {
    // cause chain carries the original metadata failure
    Throwable root = e.getCause();
    LOG.error("Regex table path discovery failed", root);
    // retry or abort depending on root cause (connectivity vs config)
}

Prevention

Pre-check DB connectivity and credentials before discovery
Verify the dialect supports the target database's metadata queries
Add retry for transient network errors during discovery

When it happens

Trigger: Any exception inside regex resolution — catalog getTables call fails (connection error, SQL error querying metadata), or building a JdbcSourceTable from a matched catalogTable throws; processRegexTablePath wraps it in "Failed to process regex table path: <path>".

Common situations: Database unreachable or credentials invalid when the catalog queries metadata; unsupported dialect for the URL; metadata query fails due to permissions; transient network failure during discovery.

Understand the failure class

Background: Database query failed: Internal Server Error 500s wrapping SQL, Prisma, and connection failures — what to check first — this error's family across 16 libraries.
