-------------------------------------------
Summary: Failed connecting to Avatica Server specified
EXPIRY_DURATION=0
Key: CALCITE-4178
URL: https://issues.apache.org/jira/browse/CALCITE-4178
Project: Calcite
Issue Type: Improvement
Components: avatica
Affects Versions: avatica-1.17.0
Reporter: Masayuki Takahashi
When setting JdbcMeta.ConnectionCacheSettings.EXPIRY_DURATION=0 to JdbcMeta, it
fails connecting Avatica Server at "connectionSync". Same for
JdbcMeta.ConnectionCacheSettings.MAX_CAPACITY=0.
It causes that these settings disable to cache connections and throwing the
exception.
