* There is now experimental, optional support for large indexes (disabled by | |||||
* default). This optional support can be enabled via a few different means: | |||||
* <ul> | |||||
* <li>Setting the system property {@value #USE_BIG_INDEX_PROPERTY} to | |||||
* {@code "true"} will enable "large" index support accross the jvm</li> | |||||

* instance will enable "large" index support for all tables subsequently | |||||
* created from that instance</li> | |||||
* <li>Calling {@link #getTable(String,boolean)} can selectively | |||||
* enable/disable "large" index support on a per-table basis (overriding | |||||
* any Database or system property setting)</li> | |||||

<question>Why am I getting an UnsupportedOperationException (or | |||||
IOException) when updating an indexed table?</question> | |||||
<answer> | |||||
Previously index update support only handled tables with small numbers | |||||
of rows. When the index size limit was reached an | |||||
UnsupportedOperationException (or possibly an IOException) was thrown. | |||||
As of the 1.1.14 release, experimental, optional large index support | |||||
has been added. This support is disabled by default but can be | |||||
enabled via a few different means. Please see the <a href="apidocs/com/healthmarketscience/jackcess/Database.html">Database javadocs</a> | |||||
for details on enabling large index support. | |||||
