[GitHub] [iceberg] rdblue opened a new pull request #1203: Remove table cache expiration
rdblue opened a new pull request #1203:
URL: https://github.com/apache/iceberg/pull/1203
This removes table expiration from cache in `CachingCatalog`. As long as a reference to a table exists, the cache should continue to use that reference so that writes update the table for all queries. The cache still uses soft values, so once other references are removed it can be garbage collected if memory is needed.

@aokolnychyi, yes, that's what might happen. This would affect tables that are in logical plans that are cached or stored as temporary views.

Are we saying that we can hit a case when a table may be persisted as part of a logical plan in `tableRelationCache`, then it gets expired after 1 min from our catalog, then we have a write that loads a new table instead of refreshing the original one? And as a result, the table cached in `tableRelationCache` shows outdated results?
